it is like i have super swampers under my truck now? it is pretty loud. and the front right side tire does not spin very well whe i pick it up? and that side gets pretty hot?

you think it is a wheel bearing?

 

[AllStarPSD]

jack up the front end ... grab each tire at 12 and 6 and push/pull back and forth. if you can move it, you have problems.

[joedirt]

if it moves at all....its a costly part...front hub assy..stealer wants close to $450

i just got done doing mine

 

[firemedic8104]

All seals, studs, lug studs and bearing assembly about $275 from powerstrokeshop.com

 

[iwantaturbo]

no movement at all from eather side when i grab and pull or jurk on them when they are on the jack?

i have aftermarket sloted roters and i dont think they are warped? but it is the wersted when i hit the brakes and turn. teh side that drags more than the other side dose not get easy then hard like if a rotor was warped?

 

[iwantaturbo]

anyone

Yep, get yourself a Hub Assy and the inner and outter O-Ring seals. One is Yellow and the other is Black. You can only get the seals from a Ford.

did you ever fix your problem? My 99 started this th other day, Im thinking maybe its the 4x4 hubs?

[iwantaturbo]

nope can't pin it down!!!!! i don't think it is the hubs they work great when the wheel is off the ground, lock and unlock as they should

 

[FLpowerstroke]

Well I figured out what mine was. The spindle/axle bearings took a dive on mine then took out the hub. You can tell if you grab ahold of the u-joint knuckle behind the hub and try to shake it. Mine moves all over the place, maybe 1/2" of play. Might want to check this on yours. Good luck & I hope this is not your problem too.

[iwantaturbo]

just went and checked and thats not it!!!! both sides on mine are good and tight? i have no idea? im going to put defrnet tires on it tonight and see if that is it?

 

[iwantaturbo]

ok did some more testing today. took tires off the front and put difrent ones on. no change????? i have one warped rotor but it is very slight and could not be doing this!!!!!

it only does it when i slow down from 20 to 0 and it sounds like a speaker sweep. it starts hi and gets very low and louder!!!!

it does it in nutral or in gear. it does it with the brakes or with out????

it also does it in 4 wheel drive?
what can it be?

 

[Oneof6]

Just because it SOUNDS like it is coming from the front doesn't mean that it is. The scenario you describe can also be differential carrier bearings in the differential and other things not in the front. 106

 

[iwantaturbo]

lifted up the back every thing seams smoth back there ujoints good and both tires spin as they should? how would i know if it was in the rear end if it feels ok?

i need to get this truck back but it is not driveble like this!!!

I have the same problem from my driver side front tire. It's slightly quieter when I let off the gas, but still there. I'll be taking off the tire/wheel to see what's up, but I'm suspecting wheel bearing. My problem occurs whether in neutral (coasting), and at all speeds and in 4wd, or not. I desribe the noise as "growling" or "rumbling". /ubbthreads/images/graemlins/shrug.gif

 

[iwantaturbo]

i can only hear mine from 30mph to 4 mph when stoping? not crusing or speeding up?

First I would eliminate the front. Take a test ride on a smooth road. Lock the hubs in, if the noise goes away or changes greatly then it is the spindle beairng in the front hub. If the doesn't do anything then next jack up one front side at a time, remove the wheel and brake caliper. That should let it roll without any brake drag. Put the rotor and wheel back on thighten it up with a few lug nuts. Roll it it should roll smoothly with no grinding or noise. Take the wheel and pull in in opposite directions at 0 and 180 degrees, top and bottom. There should be no discernable movement in the bearing. Check both sides. If it is not there then it is likely the U-jonts in the drive shaft, drive shaft hanger bearing or a rear differential part. To diagnose rear differential problems is tricky but here is what they sound like, and sometimes it SEEMS like the sound is coming from the front.

1. A whirring or gringding noise at all seeds is most likely a bad pinion bearing or one with loose preload.

2. Howl or whine during acceleration is usually caused by improper gear set up.

3. Rumbling or whirring at speed over 20 mph or so, seems to go away at highway speeds, is usually differential carrier bearings.

I went through a time with my truck when I changed hub both front assemblies chasing a problem, wasn't it. It was the pinion and carrier bearings in the rear differential. Let the dealer (mistake) rebuild it and they messed it up, lassted 18K. When it did it a second time the sound again seemed like it was coming from the front, might just be the internal accoustics of a crew cab. Anyway, this time I went into the rear differential myself, very bad drivers side carrier bearing, pitted pinion bearing races from the shavings, broken differential shim. I think that they broke the shim getting the preload and either didn't know it or said the heck with it. I am finsihing up the rebuild today.

[iwantaturbo]

so you think i should take off the cover and inspect the rear end?

 

[Oneof6]

Sorry about the late return, I am working out in the garage today. It never hurts to look in the rear end, well not more than the cost of the lube you have to drain. IMO eliminate the front end by something other than sound first. Then go to the rear end. 106

 

[Roadfrog]

This was my exact diagnosis today. I just returned from the dealer after chasing a front end noise thinking it was a hub assy. NOPE! It's the rear diff and it needs a set of carrier and pinion bearings. The head mecahnic and a few others all swore it was coming from the front too. So, ONEOF6: Any tips to share with me!? /ubbthreads/images/graemlins/frown.gif
I'll be tackling this job soon.
