I went to take off my sway bar today and I found a bunch of splattered grease on and around my driver side CV joint where it meets the diff.
After wiping it all off, I checked the CV boot for tears or cracks and found none. Then I checked the shaft. I found I was able to move the shaft about an 1/8", side to side, from where it meets with the differential.
The pass. side does not move. So I am assuming the grease is coming from that gap where the CV shaft meets the diff.
This is on a 09 DCSB with a 6" Fabtech lift.
I had sort of the same issue with the carrier bearing, where the nut had backed off after the lift and it shredded the bearings. But they don't mess with the shafts when doing the lift right? They did re-gear, so was there disassembly with that?
What do the internals look like? Is there a nut in there that may have come loose?
I'll have to take it to the dealership on Wednesday unless I can find a fix here.
