I am having noticeable shudder during light or hard acceleration from a stop AND vibration from the rear end when making a turn (only) from a stop, but not going straight.
Here is the question I need to ask,I changed my rear end fluid back in november and am reading alot of people having the same problem.Would changing the fluid have something to do with my problem,were they suppose to add something to it.some guy's are saying to put in a friction modifier is that a temporary fix.

Thanks

PS: I accidently put this under INTERIOR.PS: I accidently put this under INTERIOR.

 

If it is a Limited Slip differential, unless the fluid already has friction modifier, then you need to add it. If you don't add it, the clutches will chatter instead of slip like they are designed to.

 

Yes it is a limited Slip differential,I had it done at jiffy lube and I don't no if they put it in or not.Monday I will go back and ask them.Thanks
