Ford Brakes/Suspension :: 2002 2WD Explorer - Thumping Noise When Accelerate
Jul 2, 2011
I have a 2002 explorer 2wd. I am trying to find an answer for this thumping noise as I accelerate. My first thought was a tire. I took them to be checked and had one replaced but all are good and less than 5k miles on them. I feel it in the pedals and in the steering wheel. The repetitive sound increasing with speed. I have, in the last 2 weeks, changed front rotors and pads with no difference in sound but good brakes now. And today replaced the drivers side upper ball joint and the front ds wheel hub assy. And no difference. What may be the problem?

My brother has an 02 ford escape that he bought cheap because it needed a transmission. He just replaced the transmission in it as well as tie rod ends, front axles, axle bushings and seals. The front pads and rotors are new and the tires were just rotated. Now when you are going 15mph and up and are on the accelerator there is a severe shaking as you accelerate and a loud thumping noise. If you let off the accelerator it goes away. If you get it going fast enough it will shake so bad the mirrors will shake. He is a ford mechanic but said he is having a hard time pin pointing what it could be . He took me for a ride. He said he has had other mechanics look at it but they can't figure it out.

Im wanting to delete my abs brake system in my f150 2002 2wd all disc brakes.
I have to change the module with some kinda valve? and turn off the Abs in a tune?
I know the basics of a brake system, but im lost in the abs stuff.

This is on my 2002 Ford Excursion 4x4. I have replaced the brakes 2 times with the same results.
New: rotors, pads, calipers and grease the caliper slide pins so they are sliding properly. I have also replaced the slide pins the first time. I even lightly greased the ends of the brake pad back plates where they mount in the calipers/brake clips. There is always more brake dust on the left front wheel compared to the right front. The steering wheel turns to the left when I hit the brakes. I can't figure this out.
The one thing that seems strange is it was very difficult to get the pads and brake pad clips into the caliper. It almost seems like the pads are too tight into the clips/caliper. I am wondering if taking a little material off the ends of the brake pad back plate to allow better movement in the caliper/clips.
The left front is either grabbing too much or the right front is not grabbing enough.

I recently did a brake job on an 02 Explorer, consisted of new pads and rotors (Rear). The Slide pins were fine and the piston was not frozen in the calipers.
Shortly after the Explorer will occasionally make this "thump...thump....thump..." feeling/sound.
It is not vibration.... it feels more like passing over small bumps in the road.
It is most consistent from 30-50mph, but I have felt it from 20-65.
It is more prominent on decel, but you can feel it on accel as well.
It makes no difference if you touch the brakes or not, or if you push the clutch in and/or take it out of gear.
Speed does not seem to effect the timing of the "thumps" it appears to be the same from 20-60mph. I'm at a loss...

I have a 03 explorer with approx 160k, I am experiencing a thumping noise while driving. It gets worse on right turns and gets better on left turns. initially i thought LF wheel bearing so i ordered a hub assy and replaced LF. noise is still there. I guess, thumping noise caused by wheel bearings, i know its usually a grinding kind of whirring noise.
The noise doesn't seem to change with accel/decel so I don't think it is driveline related (diff, drive shaft etc.) should i bite the bullet and replace the rf as well??? I should also mention that there is also a shake in the steering wheel that seems to coincide with the thumping (i.e., my hand shakes along with the thumping, and the shake gets worse when the noise does)...

I have a 2002 for explorer 4wd 4.0 it won't accelerate. it's fine to 25, but it pings, and won't go over 40. I've changed to the plugs, wires, coil pack and fuel filter. I've also checked the fuel pressure, and it's 65psi. no codes are being set. I've been told plugged cat, but they're welded on, and no way to test them...

I purchased a 1992 F-250 last month. About a week ago I topped off all the fluids (including brake). I was driving it around the day after topping off the fluids and noticed that half the brake reservoir was empty. Topped it off again and did not notice much of a leak at all (I may have done something wrong, not sure what). Parked it and found a small leak in the rear passenger side brake bleeder/cylinder/line (couldn't tell exactly). Took apart the brake and found that the drum and shoes were bad, so Installed new drums, shoes, cylinders, and spring kits in both rear tires.
Started bleeding from the rear right (farthest) until no more bubbles. Went to the left and bled until no more bubbles..... decided to check the right and every time the brakes were pressed, i heard a bubbling/spitting noise (not sure exactly how to explain it) and more small bubbles came out. Went back to the left brake bled again, noticed a few bubbles, but was fine shortly after. What it might be? The brakes seem to be working ok for now though.
The right side brake (problem brake) has a newer line installed. The screw that connects the line to the cylinder seems like it is not in all the way, yet it is snug (I didn't cross threads when I installed it). I'm thinking that air may be being sucked in at the screw and eventually make it through the system... maybe not?

So I have this thumping noise, almost sounds like something is loose.The noise occurs for a few seconds when I accelerate from a dead stop and then goes away, it returns when I slow down and almost come to a complete stop.The noise also goes away when I put her into 4wd.The thump/rattle sounds like it is coming from the center counsel area and directly under the floor board in the driver seat.My car changes gears smoothly up and down while driving.
I was told it might be a transfer case problem and that it might need to be rebuilt, which makes me worry.

After I brake and partially release the brake pedal (not completely letting off) so I can cruise a little further, sometimes I have heard a quick three raps or thumps. Normal?

In the last month or so I'very had trouble with my 2002 Explorer having trouble accelerating. When I take off from a light it hesitates badly. It feels like it's got air in the tank. It does it every time I need to accelerate, including coming around turns. I'very put in fuel injector cleaner and it works fine for a little while, but then has the same issue. Yesterday morning it wouldn't turn over in the morning. I changed out the battery, but I had a similar issue of not turning over. It eventually did. I was wondering if the two might be related. Could it be a fuel pump or fuel pump relay?

yesterday i gave the 02 diesel a treat, 3 new calipers 4 new rotors, and semimetalic pads. the reason for only 3 calipers is the driver side was just replaced 2 months ago after it locked the wheel up on me. both rears were seized so i only had front brakes, and the passenger side front was leaking.
anyway, all new parts and the pedal is fantastic, besides the truck stopping again. this afternoon on the way home from the shop i stopped at a red light. breaks are rock solid. then all of a sudden, the pedal slowly sinks to the floor. but the brakes still hold. i get home and test them. again, pedal slowly sinks to the floor, but they hold. i am thinking still some air in the system, and park hte truck, with the intention of bleeding them again tomorrow.
i get out and see fluid all over the driveway. great. something in the front of the axle is leaking. the frame is drenched. whatever it is, is in front of the frame, on the engine side. what is in there, the ABS unit?

So lets see if I can put my issue into writing....
Have an 02 f250 v10, last summer replaced the steering gear box, havent had any issues til this spring.
Beginning of spring my ABS light came on during casual driving, wasn't to worried as the rear sensor often gets dirty and needs cleaned- cleaned the sensor and the light remained on this time.
While driving (and the light being on) I would at random get a very heavy vibration/shake from the front end and if I apply the brakes while that was happening the truck would pull real hard to the right, the shaking feels like a death rattle- like the ABS was firing and was using steroids, then it would go away. (the brakes would occasionally smoke a bit on the left front side afterwords)
So like that problem wasn't annoying enough, while trying to diagnose the problem the ABS light clicked off, and I wasn't able to recreate the vibration, but I noticed when I would apply the brakes, at say a stop sign, the brake would press in another inch or so (after already being stopped) and then I could hear a loud whine from under the hood.
The fun is these 2 problems seem to keep swapping positions- and I am at a loss of what could potentially be the cause- (I assumed the 2nd problem where after stopping the break pedal going soft another inch and the whine could of been air in the system- I bled the brakes and no change)...

I bought an 02 Explorer Sport 2wd back in December of '12. The vehicle actually runs pretty well. The thing I first noticed was the rear suspension seems to slam when going over bumps of almost any size or at any speed. Like if there's a sub-level manhole or something that just the passenger rear tire goes over it makes this terrible slam and sometimes shimmies (Spell check) to the sides like Inam losing control. I thought I would go ahead and change the shocks, did not make one bit of difference. I have looked up diagrams on the rear sus and everything seems to be there. Here's a picture just to kind of show what I have going on.

Just got a new to me 02 Limited v8 - 128k on the clock
Noticed today while at a stop light that when I depress the brake pedal (after being stopped) it makes a squishy sound - the pedal feels different, but I don't know if spongy/squishy is the right way to describe it, it just sounds like you stepped on a waterlogged sponge.
Now the brakes definitely don't feel as good as my XLT brakes (recently replaced it due to rod knock - 02 XLT v6). It still stops but seems like it requires more effort and almost fades a little. I initially chalked up the difference in performance to me putting new rotors/pads on the XLT - Thermo-quiet semi's with Raybestos rotors.
However it appears after some brief reading this could be the master cylinder on its way out....is that accurate? I planned on taking my pads/rotors off the XLT before I ship it to the junkyard (less than 3k on that setup), but if its the master cylinder, I'd like to do that while I'm doing all my other tune up stuff this weekend
I'm gonna put it on the lift this weekend and see if there's any brake fluid stains to see if air is getting into the system, but looking at the reservoir over the past week I haven't noticed really any decline in fluid level.

I have a 1997 F150, 4X4. My mechanic says its time for new brakes and was curious if it would be worth possibly converting from drum brakes to disc brakes??
My mechanic has quoted me $300 to do the rear brakes, would it be worth the extra money to convert??? I really don't care for drum brakes. I have done a search on the internet and every time it brings up the issue with the parking brake.

Have an 02 Explorer XLT that recently had its' ABS light intermittently come on. As well when the ABS light is off the brakes will pulsate when slowing.
Took to dealer they noted the following:
Rear sensor out .... ABS Control unit is out. Was shorted out due to Hydraulic Control Unit going out. Hydraulic control unit is obsolete at Ford.
Questions:
With all of this going on, how was I able to brake although not adequately?
Does the HCU control normal breaking too (without ABS)?
Immediately he says he would not put the money into it and wants to get me to someone to trade it in on another vehicle? While I understand the logic somewhat I do not being approached like this.
Can I get a better quote going to a mom and pop mechanic and getting second hand parts?
Is there a possibility to bypass/disconnect the ABS system and would it be recommended?
How to deal with? Vehicle is in great shape aside from mechanical issues creeping up and don't want to lay out the dough for a new vehicle.

My 02 Windstar has developed an intermittent thumping noise in the engine. A bit of history: She has been sitting for a few months because she was throwing a P303 code that I could not track down. Here in IL, you cannot renew your plates until you pass an emissions check, and you cannot pass the check if a code is stored.
Well, I got a warning ticket for expired plates, and I had my daughter's car as alternate transportation while she is in the Peace Corps, so I parked Mr. Breeze, intending to get to her on the weekend. Except for throwing the code and gas mileage being a bit down, she was running fine when I parked her.
Well, life happened, and I never seemed to be able to put the time aside, but now winter is coming and I don't want to subject her ride to the snow, so I made time and replaced the coil, plugs, and wires. But when I started her up, there is an intermittent thumping noise in the engine compartment.
I have double checked the wires, and I think I have them right. As I understand it, the right bank plug wires go on the coil towers 1,2,3. and the left bank wires go on the towers 6,5,4. Is that right?
I made a short video so you could hear it, but it is too big to upload, so here's a YouTube : [URL] .....

About 3 weeks ago, I noticed the SUV would occasional make a loud "CLICK" sound in the front steering area, usually if I made a fast turn motion (either left or right).
So today I put it up on a ramp and took a look and it's obvious there's a part in there that is coming loose. I don't know what the names of the stuff is in there, so I'm posting a photo with arrows & letters so people can tell me what's what, and also what to do.
I tried putting a vise grip on it and tightening it with a ratchet wrench on the top part (16mm), but the lower nut just spins. I decided to not go any further because I really don't know what that assembly is, what it does, if it's broke, etc.

I have a 06' Ranger 2WD with General Grabber tires that have about 30,000 miles on them and still show significant tread remaining.
Within the last 2 months, I have experienced excessive tire noise - like I am driving a Humvee or something. Also, when I turned right or left the tires would make even MORE noise - it seemed to be coming from the right front tire mostly. 2 weeks ago I had the tires rotated and the sound seems to have reduced while turning but I still have the howling Humvee noise while driving down the road. There is no vibration coming from the wheel, so I don't think it's a balancing issue. Could it be the bearings?
I also checked the PSI all around and one tire does have a slow leak but I try to keep to topped off.
