whats up w/ my lsd?

[stumble_t]

I'd like to bump this for a few added ?'s

I've got the same problem. Heavy chatter/wheel hop from the Right side only, in RH turns where I'm breaking traction. CSB is newer <2yrs old. New Diff oil + modifier.

Possibly the friction plates shot on that side? I'm going to give it the torque test as soon as I get a chance.

Any insight is appreciated.

6 month bump......
csb bearing was effed, mechanic wasn't confident on driveshaft either....call to wholesaleimportparts later= feel like a new car.

[FetusGoulash]

are the friction modifiers necessary w/ 75w90? or are they present already/

Just look for a gear oil that specifies to be used in LSD rear ends. There are plenty out there to use

Not to take this topic off track, but I was looking at a couple threads about this same issue and some people were suggesting it could be the CSB. Either way Im getting under the car tomorrow to investigate

RedLine 75w90 includes friction modifiers, Redline 75w90NS does not. I don't know about Royal Purple.

i have Royal Purple 75W-90 gear oil in mine. No problems what so ever. 2.93 LSD

75w90

[raafhimself]

alright.... redline 75W90 or 75W140???

[nando]

you can buy limited slip additive from redline. Somewhere I saw how much you're supposed to put in if it's been filled with straight gear oil.

Is it different when you are turning vs going straight?

makes no difference

do you have an LSD additive in your diff oil? they will chatter if you put in straight diff oil with no friction modifiers.

thats what im leaning towards, had a mechanic swap the diff for me, not sure what they put in, i wanted a second opinion before i put in some redline

Wheel hop? How old is your shocks?

or weight pulling that side down and causing rubbage
