rear axle noise

[towingnut]

i get a slipping feel and noise in the rearend of my 1999 dodge ram 4x4. I have removed the inspection plate and didnt see anything wrong. I refilled the rear end and put 1 bottle of the lsd additive . its not as bad but its still there. it mainly makes this noise and feeling when i am turning and in a bind turning in the woods.can somebody please tell me what i need to check and be looking for. thanx lee

I am having similar issues and am afraid I'm going to lose the rear end soon. How did you go about filling it?

[towingnut]

i just drained and cleaned the casing then added the lsd additve the filled withfresh gear oil

Thanks, Nut. I guess that's my real question here. I'm not much of a mechanic. Is there a drain plug on the differential and where do I put new grease in at? I really don't want to drop the pumpkin cover.

Thanks for the help!!

To Drain it you need to drop the pumpkin cover, also a good idea as you an check for metal filings and look for slop in the gears.

just a guess but have you checked out your wheel bearings?

[dennyge]

Good idea. Let me give you all some more information as to what I am experiencing and what I have done.

I have a hum coming from what I am fairly confidant is the rear end. I took the truck in and had an additive added to the differential (a Wynns product designed to quiet the rear end) and still have the hum. What confuses me is that the hum is only there when I have the accelerator depressed. When I let up on it and coast, the hum goes away. I assume the differential is still moving while coasting which should produce the sound still.

I am really lost on this, so any help would be much appreciated.

If its humming without acceleration, then it may be coming from your tranny or torque converter vs your rear end.

just had that problem well it was the fucking drive shaft off balance and u joints plus carrier bearing . plus the god damm drum breaks . i rebuilt the entire rear end plus every sensor in the tranny and intake and that never solved the problem until i got the drive shaft rebalanced. mopars are like high maintance women they need attention all the time or they give you problem just like a chick !!
