Ford F-150 - 1997-2003 :: 2002 - Grinding Noise From Front Differential
Oct 31, 2013
I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad, what it is. I am very mechanically inclined but cannot figure it out.
Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around....

For starters I have a 1999 F-250 5.4l changed all 4 ball joints about 15,000 miles ago. I have been hearing a grinding noise coming from the front end for the last month only when I turn left and at slow speeds. I was servicing the TC so I threw it in 4 wheel to check it and it wouldn't engage until I started moving. When it did engage it was a bad grinding/ clunking sound coming from maybe the differential.

As I was laying under my truck today I noticed a drip under the front differential, it looks like the cover is leaking by the factory RTV gasket. This is the 00' F150. How hard is it to remove these things? It looks like the front cover mount makes it difficult....

I bought my current truck this past December (2002 SCREW Lariat FX4) and recently had my first reason to engage 4WD. I noticed a rumbling noise at speed (35-40mph.) After searching this forum, I checked the heat shield near the front drive shaft, and it is not rubbing. Everything looks to be in good working order. The sound is coming from somewhere in the front driveline, not the transfer case, as it the sound continues after the t-case is switched to 2wd, before the center disconnect disengages.
Checked the front diff fluid and it is topped-off. The drive shaft has some significant surface rust, so it could be the u-joints, but it's a pretty straight shot from the t-case to the front diff, so I don't think the sound is coming from there. Where the noise is coming from? CV joints in the half shafts, perhaps? Truck has 106K miles on it, and is in immaculate condition. I doubt it's ever seen any serious 4WD duty, but it did spend it's first two years in the Detroit area, so it may have seen some winter highway use. My last truck was an '01 4x4, and it was always whisper quiet in 4WD.

2002 Screw 4X4 with 5.4 ... Truck has 180K miles.
Howl / Growl noise we think from the front. Both front wheel bearings have been changed without improvement. A rotational issue as it only does it when moving and still does it if you put it in neutral and let it coast.
2 WD or 4 WD does not seem to make much difference. Been checking and testing everything without success. Drive shafts and u-joints are tight etc.
How to test it? It was my truck and is my son's truck now. They have run it on a hoist and tried to determine where the sound comes from. Going to try that again but it might be different when the wheels are not on the ground and there is no weight on things.

I just came back from a long trip and during the 400 miles drive I started to hear noise coming from my differential - kind of like a constant high gear loud noise. I will hear this noise when I start to accelerate and it will only gets louder and louder as I go faster and faster. I had a pinion seal leaked fixed last week and I checked the fluid and it is full.

I have some pretty bad grinding/growling in the front of my 2005 Explorer XLT 4-door. It is ABSOLUTELY NOT a wheel bearing. The noise seems to be coming from the front left wheel, and you can feel it when turning the hub by hand. I've changed that hub twice now (took a chance that the first one was defective), but neither made any difference. Both were torqued to 184 FtLbs per spec.
I took the outboard end of the left front cv shaft out of the hub and turned it by hand, and something at the inboard end felt crunchy. So then I pulled the shaft out and checked it over, and both sets of splines and CV joints are good. Axle shaft bearing in the differential looks good too---rolls well and no visible damage to the rollers. I'm thinking that it's got to be something in the front differential like a carrier bearing. The odd thing is that when I drove it with my Chassis Ear tool hooked up underneath, the noise was picked up at the left front knuckle, with nothing really audible from three different points on the differential case. I'm stumped on this.
Is there any safe way to drive the vehicle with the front CV shafts pulled? I'd like to isolate the front diff to be sure it's the source of the noise.
The noise does quiet way down in right turns, but the FR hub bearing was pretty quiet with the Chassis Ear hooked up. The noise starts at 20mph and dissipates above 45mph. Not like what the bad bearings on my Escape did...those just kept getting louder.
Are these Explorers known for front diff weaknesses? How can I find out what gear ratio I have, in case I decide to replace the whole unit (a used one is half the price or less than the rebuild quote I was given by a local shop).

2002 F150 XLT Supercrew 4x4 5.4L V-8, non-7700 payload
Was feeling a little grinding in the front end a couple weeks ago. Turned out to be simple, brake pads were low, and the wear indicator was causing the mild vibration (though no noise). Replaced the pads, all was good.
Then in the middle of a 50 mile drive around the area, the ABS light comes on. Found the front right sensor was bad. Replacement. Put it on, ABS light went off, all is good. Drove probably 30 miles over the course of the next day, then light came back on. Tested the same sensor, and get no resistance. So the new one is bad.

My friends truck is having a problem, and I haven't found any info on the specific issue. when you shift from P to D and accelerate, there's a slight grinding clatter in the tranny i think, bump it to 2 and the noise is completely gone! pull it to 1, and there she is again, also in reverse it does this, speed is not a factor, only the specific gears. i had read a thread which mentioned a "sun gear", and also that 1st and R are on the same bands?
I believe it was for a manual tranny that I had read about, but what this could be?! he's got a slight drag on the rear brakes, i assume it's his E-brake, could that have caused a transmission failure? We've removed the driveshaft and checked u-joints and all, nothing there, but when the truck reverses on the ground, you can watch the driveshaft bounce like it's binding. We grease the slip joint while we had it off, and we were able to spin the rear wheels by turning driveshaft w no problem while off the ground.

I'm trying to find out why my truck has a grinding noise on the passenger side when my truck first starts driving for the first 1/4 mile. It stops after that or when I apply the brakes. Do I have a brake sticking or something more serious?

I just had a new clutch installed and now I am have a grinding noise when putting it into 1st gear and when I change from granny to first it will grind also. I did not have this issue before having the clutch replaced. I have also just had a new hydraulic clutch kit installed.......

I recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.
Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.
I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.

I have a '96 jeep grand charokee Laredo with what I've been told is a bad differential. The bearings and gears are all shot, but can't afford to get a new one. I have taken off the front driveshaft to try and make it drivable again, but it is still making the grinding noise it was before. As well as catching real bad. Just wondering if I need to bother with it, or even attempt anything further.

My truck has been doing great over here in Germany, and I want it to stay that way lol. I know the snow is fast approaching here and figured I should test my 4x4(I usually do monthly anyway). After switching to 4-high and making the first turn in the open parking lot, I heard a lot of popping and grinding from the front end. I straightened the wheel and out and the grinding /popping continued.
I stopped, got out of the truck to try and lock the hubs to see if that would fix the issue. turns out the passenger side hub is locked up tight. I couldnt move it by hand and wasnt about to attempt to move it with added leverage.
What this could be? maybe a collapsed vacuum hose? but then I should still be able to manually turn my I hubs I would think.

I have a 2003 f150 4X4. Whenever I go around a round about slowly, the truck sort of grind under the frame and shakes a little bit like I am in 4 wheel drive.

1997 4.6L.. Have an intermittent grinding / dragging noise coming from the pulley (?timing) area that I'm trying to pin down. Both the alternator and tensioner were replaced prior to the noise starting. The ac compressor and the power steering pump are original. The fan clutch was replaced about 4 years ago and the water pump 8 years ago. Timing chain / guides / tensioner are all original.
I don't notice any of the common ps pump indicators (whine increase when steering) but noticed the fluid level was down slightly and that the pulley seems to have some inward - outward play with the belt off. I also don't have any other engine symptoms like rough idle or any codes being triggered. How to isolate the culprit?

I may, or may not have had to jump a curb at 40 mph to avoid rear ending another car. Truck is a 2003 F-150, single cab stx package, 4.2ltr. Long story short, no damage to my passenger side front tire or rim that I can see, but I do have a horrible grinding noise when I turn the wheel either direction. The truck still turns properly, power steering fluid is level. What should I start replacing first?! She's got about 90k miles on it, I'm sure a lot of the suspension parts are due, just need to know where to start!

I have a 2000 F150, 94k miles, manual transmission, 2WD
About 6 months ago a slight squeaking sound started when only backing up. Now its progressed to a sort of grinding metal on metal sound with regular driving as well as in reverse. I can hear it the most when its in gear and I take my foot off the gas. I changed the breaks, checked the wheel bearings, did a clutch test, and the u joints look fine. Something weird happened yesterday, while raining out, it didn't make a peep. My drive shaft and u joints have a layer of rust on them...could that be a cause of the noise, and it went away when wet?

I bought this van (1995 chevy van 20) last year and the rear end made some sounds but not as bad as its now.
So, after buying it I decided to open up the rear end and inspect for any damage to suggest it needs repairs. No signs of metal chips, nicks, or any wear on the bearings and gears. After a while of driving it I decided to remove the carriage and pinion from the rear end to give it a close inspection. After doing this and finding no clear sign of war or damage, i decided to replace the carriage barrings to see if that made a difference. After placing the new bearings back on the carriage, pinion back into the rear differential, and trying to do it all by myself, i lost the marks i had placed on the carriage bolts and clamps since I had little time to get it back together.
After that I had no other choice but to place the clamps bolts where i could estimate they belong. I was done, then drove it and some of the noise went away but a grinding sound on decelerating emerged. Well, now that sound is gotten worst and its more like a grinding sound. I can assume that not placing back the bolts and carriage clamps back changed the position of the carriage relative to where it was, but am not 100% sure. how can I correct the positioning of the carriage? if that is not the issue what test can i perform to find the culprit?
