Limited slip diff - concern or not?
My 06 XK Limited has the QDII with Electronic Limited Slip Diff (ELSD). Only had it about one month now and I am trying to understand if it is operating correctly or not. I have owned multiple Jeeps before with true lockers (ARB, etc) as well as a Grand Cherokee with the QDII and Vari-Lock diff's so I understand lockers and what they feel like in different situations. However, my XK ELSD is not acting like I would expect.
When I first got my XK, the clutch plates in the front diff would chatter a lot when making a sharp turn on dry surfaces when I first started driving it each day or after it had sat for awhile during the day. Once it had warmed up, there was significantly less chatter on a sharp turn and no feedback in normal street driving. I had no info on what the PO had done to service the diff's so I did not know how many miles were on the fluid nor if he had added any of the added lubricant that should be used in this type of diff. I suspected that the chatter was due lack of the lubricant additive or excessive mileage on the fluids so I change the fluids in both diff's and included the extra lubricant. That was about 200 miles ago. Since then, I have seen a slight reduction in the chatter but not as much as I would have expected. Currently, I still get some front diff chatter on sharp turns when diffs are cold but it quickly dies down as it warms up but never totally goes away.
Can I expect an improvement with more miles or is this this normal for the ELSD?
