If you go straight its fine...

If you turn it and lock it in a parking lot it makes noise. On regular high speed it makes no noise? Is this just the LSD maybe? Im picking up a rear diff for an awesome price but need to know this first.

 

How much noise are your talking about? A LSD doing its thing shouldn't make overly obtrusive noise. If it does, this is usually a sign that the wrong fluid has been used and the health and condition of the LSD may be compromised.

 

i also get a sound from the rear when moving from a dead stop with the steering fullly turned. i just purchased the car a few weeks ago and its CPO...should i take it in?

 

If you've got coverage, why not? May as well be safe than sorry. Can't really tell if you've got a problem over the net.

 

i dont have warranty sooo help meeee

 

Like I first stated, the LSD could be going. It shouldn't be making any sort of obtrusive noises during the "figure 8" test. Can't really help you as I can't hear what you hear.
What kind of fluid have you been running in the thing? You didn't comment on this, so not much more can be said.

 

I have the same noise [when the steering is turned] and there is a distinct couple of clicks - it almost seems like the rear end is slipping - before it sorts out.

I have a 05 with around 8,600 miles, and have had it since new.

I do not drive agressively.

 

With the Torsen differential there is a gear displacement that locks the rearend up and that can make a little noise when being activated. You may hear this.

 

Its just the LSD groan. All diffs do it....its just doing its job.

It should be a low pitch sound....like .....grrrrroooooooaannn.

If it is, its normal.

 

thanks!
