GRINDING NOISE FROM REAR!

[specTAKular]

I have been experiencing a slight, but very noticeable, grinding noise from my passenger side rear. It only occurs when going from a standstill when the car is under load (i.e. my 260 lb. buddy or heavier) on the passenger side. I have had the differential fluid changed and gears were fine. Seems to be something more like a bearing.

Anyone else have a similar issue or can help me out with this?
Thanks in advace!

Had the same problem, couldnt narrow it down. Had the entie rear end replaced. It went away. But that was under warranty so didnt care about the cost. Maybe a wheel bearing / axle bearing?

Maybe a wheel bearing / axle bearing?

+1 Agreed.

Thanks guys, i'll look into that.
Do you know how difficult of a job this would be to swap out? Are there any 'special' tools needed?

It's kind of tricky. You have to pull all of the brake hardware off, unbolt the brackets, drain the differential and remove the cover, push axles in and remove c-clips, remove axles, then remove bearings with a slide hammer and rear axle bearing removal tool. If you're brave, you can tap the bearings in like I did with a big 4x4 hub nut socket and a rubber mallot, or get one of those bearing/race installer kits. You'll know if it's a bearing, if you raise up the back of the car, and the tire has alot of movement front to back and up and down. I believe it might be something else though. Are you lowered at all, and do you have steeper gears installed?

No, not lowered at all and gears are stock. Had a mech. mention that there may be something grinding on the drivetrain so i'm going to try and jack it up to take a look under there in the next couple days.

any other possible thoughts are welcomed!
