2006 SV6
I have a 2006 SV6 sedan which has done 80,000kms. For the past few months there has been an intermittent clunk when you slow down at intersections, put the foot down and in reverse. The clunk can be 1-3 clunks and it sounds like it is coming from the diff area. The car has been to 2 respected mechanics who say it is OK. Any suggestions??

This question has been answered in a thread somewhere here very recently. It is the differential engagement in drive (dull thud at slow walking pace) and not something to worry about, nor is it "excessive wear".

VZ diffs are **** and renowned for backlash.

I rebuilt mine at 100,000 because it got that bad and it was much better afterwards.

VY has the same problem. I started a thread on it a year or two ago. It's known as cyclic diff knock and is caused by some play in the diff. Can be repaired by replacing some curclips or something?? Mine has done it for two to three years now and doesn't bother me, very common. Mine would especially do it at roundabouts when I would back off on the throttle then accelerate. I've since learned to simply drive "easier" and avoid the knock occuring most of the time.

I have a VR auto and it does the same thing, seeing as the VR and VZ are totally different cars , would it be the same problem?
