Check the rear axle nuts. If loose plan to replace the wheel flange and possibly the stub axle.

Dennis,

Subject: 1988 vanagon noise

New cv joints installed
Mechanical thumping in rear passenger side when only turning right while accelerating around a corner
The faster I drive the noise increases the same
If I coast around a corner no noise
No rear end noise when the van is just started only after it starts to warm.
If testing the van in a Walmart parking lot by slowly driving in circles no noise
I took everything out of my Westy that could rattle
Any thoughts?
Losing my mine in Vermont
