Ford - F150 :: 2002 - Rhythmic Shake Like Driving Over A Bump
May 24, 2016
I have a 2002 F150. Small V6 regular cab 8 foot bed 2 wheel drive.In the last couple of months it has developed a rhythmic shake that is more like driving over a bump. It is really quite similar to driving on a road where all the release joints have been recently tarred so you go over a slight bump every second or two. I actually tried to convince myself that is what it was for about a week. Seems to be coming from the front driver seat.I previously lived in Mexico and the pot holes there would occasionally shear the bolts right at the lug nuts. Not too different than a car that was damaged like that, but I checked the lug nuts and it seems ok.The bump does not transfer into the steering wheel.Being a 14 year old ford the motor doesn't idle as smooth as my wife's new Toyota, but not bad either. If I let off the gas the bump doesn't stop. I haven't changed into neutral while it is running to see if that stops it.Tie rod?Axle? What to check or if there is a picture of something I could post that might tell you what is wrong?Planned on a camping trip this weekend with my wife. She is going to be ticked if we have to cancel.

My wife and I have noticed that at right around 50 MPH we can feel a BUMP BUMP BUm that is very slight. It almost feels like you are driving over expansion joints on a concrete bridge or something just not as severe -- a more subdued BUMP. It doesn't matter if it's in Drive, Tip, or Sports mode it's still there. Mostly in 5th and 6th gears (which is right for the speed we're feeling this at). It feels too slow to be a tire problem so I'm thinking it might be drivetrain related. It doesn't do it everytime you get to 50 but at least once on the way to work you can feel it.
I'm also having a problem with a bad shimmy when we cut the steering wheel hard to make a turn from a complete stop. The whole car shakes until you get the wheel back to the center position it's like glass from then on. I was researching an earlier post and they suggested that uneven wheel pressures might be the cause for the second problen. They mentioned that it had to do with the AWD and differential sensing different wheel speeds from large differences in the air pressure. By the way we have a V8 w/ 19's and no Air Susp.

I just had vehicle inspected and replaced the wheel hub assemblies on the front Left and Right wheels in order to pass. Now while driving strong shaking occurs occasionally when over 60+ mph or at any time after a hit a bump in the road. have to slow down below 30 for it to stop.

I have an 09 F350 (116,000 miles) that I have only owned for about 3 months. I got it pretty cheap but it did have a front end issue. Drives fine most of the time but hit a bump just wrong at highway speed and it goes into a shake and wobble that feels like you just blew a front tire. Took it into my shop, not the dealer and was told I pretty much need a front end rebuild. Kinda what I figured I would hear.

About 3 weeks ago my truck decided not to start after having driven many miles. It has happened again after a day of driving with multiple stops. It cranks but doesn't turn over. Mechanic could find no code errors, there is no service engine light. Problem?

I've got serious shake going on in the right front. I ordered new wheel bearings but can't figure out how to replace them. Been working on tractors, trucks, boats my whole life and this is embarrassing. '82 F150 straight 6, 4wd, standard trans.

Bought an Ex last year with 200k miles on it. Started having issues this summer. First off, it will shake when pushing on the gas. If I let off the vibrating stops. Secondly, if I tromp on it, the speedometer drops for a second then comes back up and the "ABS" light comes on for that split second too. Thirdly, it will randomly die on me. This morning dropping off the kids at school, it died 3 times while backing up. Starts right up, but will just kill, no sputtering.
The Check engine was on, so I took it into Advance for a reading. Computer said there was an issue at the rear output sensor. So, I replaced the Speed Sensor on the rear differential last night. Take it for a test drive, and the check engine light is still on, but the Overdrive light on the shifter is flashing randomly.
Now, I assume the shaking and dying is Fuel related. I am ruling out the spark plugs as it idles fine (maybe I'm wrong). I purchased a fuel filter to replace that and hopefully it works.

As I'm driving down the highway my steering wheel tends to shake a little bit. My tires are fine but are offly loud . They are balanced and all but just sound loud u can hear them rolling inside the cab sounds maybe like if I had mud tires but I don't they are all terrains. . I was told maybe the bearings but I don't know.

The first time it happened, I wasn't monitoring any PIDs as I didn't have my phone with me. Not really sure if I hit a bump or anything, it just stalled. I pulled it off to the side and put it in park and started cranking. Turned over rapidly but wouldn't start. I started freaking out thinking what am I going to do? Shut the truck completely off and waited a couple minutes and then turned the key and it started right up. Drove to my destination and didn't have another issue.
I'm only driving my truck on weekends as I have a company van and I can't park my truck at the condo I'm living at right now. So sometimes it's a few weeks between drives. This has been the story of my truck use since I nought it 3 years ago. In fact I know my turbo is sticking as the most boost it builds is 20-22 psi. I probably have a sticking injector too, as it smokes unburnt fuel until warm.
So the last few weeks when driving, I've noticed that if I hit a big bump, occasionally it dies again. What I've discovered is that it won't start unless I shut the key off entirely. Meaning, if it stalls I put it in neutral as I coast, shut the key off as far as it will go and it will start up. If I just throw it in neutral and try to start, it won't.
Watching my Torque Pro display, I've noticed that it locks up (like normal when I shut the truck off w/o shutting the Torque app off). The display then has read lower voltages than normal for FMP, FLP, FVP (main, logic and vehicle? can't remember ). FMP is normally at 48.5v and the other 2 hover around 13.9v. The last time it stalled, I noticed 9.3v for FLP and FMP was 23.4. I'm not sure if this is what it shut off at or if I panicked and tried starting it w/o shutting the key off entirely. So please don't take those readings as gospel.
I scanned it for codes, but nothing popped up.

I have a 92 ford f150 that ran great up until I was driving the other day and my trucks engine just shut off, like i turned the key off. It wouldn't restart. Towed it home, let it sit, and tried again..cranks fine, still wont start. replaced the coil.. Cranked it for about 5 min off and on and it barely started.. Let it run for about 5 min and shut it off, wouldn't restart. Replaced the icm....and again, cranked until it barely started, then it wouldn't restart. Today I replaced the ignition switch, and the cap n rotor. Now It'll crank for days..but still not starting. I have 40 lbs fuel pressure at the rail, plugs, wires ,all new. new fuel pumps also....

About 4-5 weeks ago my 2002 F-250 7.3 just died with no warning after coming off the highway and since then it hesitates/dies when hitting a bump or while applying pedal with the A/C on. The code that keeps popping up is the P0344 "CPS" and the code for back pressure sensor... I have replaced the CPS twice "making sure the 1st one was not bad", the back pressure sensor and the tube the goes the manifold, and fuel filter and still having problems... I didn't know if there could be a fuel pump issue or something else?

The best that I can describe what it feels like is at around 30 to 40 mph it shakes like your going over the side shoulder little pumps with both wheels. Only at those speeds... I all ready changed struts, tires, rack in pinion, upper and lower ball joints and tie rods. I have not change the tie rods that go up and down from struts to spindle its like 6" long or so can that be it? Or CV shaft?...

Last night while driving home in the rain, I cleared the windows with the wipers, and lowered the rear passenger window so that my dog could have air. I then proceeded to drive. I then lowered and raised my drivers side window and the passenger window to clear them of rain drops so that I would have an unobstructed view. I turned off the wipers, as it was only misting and then closed the rear passenger window. About 3 minutes later, I wanted to wipe off the windshield again, however, the wipers would not come on. I then played with the window buttons trying to open them, but they would not open, and the interior lights would not come on. However, the doors would lock and unlock. I thought for a second, maybe the anti-theft system engaged somehow. By this time I was sitting at an intersection - at a red light, waiting to turn left. I shut the car off, to see if something in the vehicles' computer system needed to reset itself. I waited a couple of seconds, and then restarted the engine.
By this time, the light had turned green, however, I could not get the car to switch from park to drive. I tried numerous times, but to no avail, the vehicle was stuck in park. To make a long story short, a while later after the police came, one of the officers googled the problem for a 2002 Ford F-150 truck on his car computer. He found that the vechicle had to be turned off to where the dashboard lights were on, foot pressed on the brake, and only then could the gear be switched into neutral in order to be started. Only after going through this routine was I able to shift the vehicle into drive. This is the first time this problem has ever occured. The vehicle has138,500 miles.

I've had my mechanic work on this issue (the engine misses), and for the past few months thought the issue was resolved.... Truck is 27 years old and has only 75K actual miles. Here's what I have done.
Installed rebuilt carburetor - 2009New plugs, wires, distributor cap and rotor - 2010Adjusted carburetor, timing, and choke - Feb 2012
I normally drive it every couple days, yet during last winter it set up for a couple weeks with 10% ethanol fuel. In early spring, the engine started missing while driving (about 1/3 of the time). After taking to the shop a couple times, my mechanic basically gave up. I believe it's time for a new mechanic. I may also give up and just get a newer truck, but not quite ready yet.
I suspected water in the tank, knowing that ethanol can attract moisture, so i ran the tank dry then bought 5 gallons ethanol free fuel (i live in the country where we can still find it). Engine started, ran great for a few months, and i thought i had solved the problem...until yesterday, when the engine started doing the same thing again just as it did when the problem originally started.

First issue I noticed was the brake pedal/steering vibrating - my assumption was "warped" rotors (I use warped in quotations so that this does not turn into a discussion on whether or not rotors can warp.) I checked the front and the rotors and pads seem fairly new, the back pads were pretty much gone so I replaced those. Reduced the problem somewhat. Yes I still need to do the rotors but would rear rotors that are warped cause that much shaking?
Next issue I had noticed was that for a while that the car would shake somewhat when accelerating usually going up hills or when the car is under strain. Then I noticed that when I had the car fully loaded with passengers it would shake fairly noticeably when accelerating every time.
I thought the problem may be worn plugs since it seemed to come from the engine, well after 2 days and many hours of work not the problem.
By the way I bought the car only a few months ago and have very few service records so not too sure what has or has not been done. The lady did keep up with the maintenance though.

Ford dealership is having problems with heater core repair. 2002 Ford F150 Supercrew. Problem is antifreeze (or early on just smell) in the cabin. 4 heater core replacements in 2 years. A hose (?) replaced. Electrolysis kit replaced. 4th heater core replacment finished yesterday. I know that I need to let the dripped antifreeze work out of the system, but I am smelling mild antifreeze this AM. Usually gets worse over 2-3 days then I have to take it in. What might be being missed here?

I have a 02 f150 4x4 5.4 135 k the transmission will not shift into drive unless you rev it up to about 1500 rpm and when it shifts it goes in very hard but when you get moving it seems to work ok but every time you stop or slow way down it does the same thing. It works fine in reverse and the oil and filter is good. I am thinking TC but i dont know ...

Was looking for some advice on what my problem may be. I just replaced the slave cylinder on my 02 f150 4.2 and two days after I changed it on my way home from work my truck jerked when I was about to turn into my driveway. Then when I stopped I put it in neutral snd it started rattling really bad it stopped when I pushed the clutch in And when i let out it started again. It sounds really bad and im hoping its something I can fix my self and not terminal.

Once I had driven for about 15 minutes and the truck set for about 5 minutes. Then it would not start. Another time, I drove for about 20 minutes and it cut off while driving in a parking lot. I have had 2 different shops take a look at it and they cannot duplicate the problem. They have run a bunch of diagnostics and tried their selves but it always starts for them.
