2008 t4r V8 idle speed

[swegen]

Idle is ~ 800 in N goes to ~650 in D
So brake must be held on to keep from running away!
When coming to stop , brake ON till stop , release brake pedal, CLUNK !
I believe it's a drive shaft spline that is under torque load until brake is released and then splines can slip back to "at rest" position.
So is IDLE too high? Or something defective in axle location links? Or motor mount? Or?
How to lower idle? What is idle spec?
Any ideas?

Idle is normal, lube the zerks on the driveshafts.

I think I read that somewhere before. Gonna do the shocks/springs this coming weekend at which time I will also do first grease oil filter and tire rotation. Any grease preference for splines? BTW how many zerks?

Normal automotive grease is completely acceptable - I use M1. There are 8 total zerks. Each u-joint has two of then.
