I have noticed a bit of a clunk as my 300D changes gears.

I recently bought new aftermarket (GSM) axles. Had to make a mod of the axle to hub sleeves/bolts because the aftermarket splines must have fitted differently. Thought clunk might have been these splines, so today checked the tension on the M8 hub bolts. But they checked out at 30NM torque and seemed fully inserted.

I jacked wheels fully off ground and rotated wheel back and forth. There is quite a bit of slack without the driveshaft moving.

Car has done 450k+ km. Is it normal for the diff to have that sort of lash (about 1 1/2- 2" at tire surface.)
