Hmm.. you still have this problem ?
Please refer the manual, step 3.1 :
The G22 bolt is too tall.
So the E12 bolt (the 2pcs in front) on the step 3.3 cannot keep the upper diff cover in tight condition, the 2 bolt hitting each other(G22 vs E12).
Pls check the diff assembly (mounted in the car) if you can move the diff up and down a bit, most likely you have this problem. Worn out U13 bearing could make that condition also.
Worn outdrive only make it worse.
Lower the G22 bolt 1mm, .5mm should enough.
Replace 802305 + 802306, or use the old one but find a M3x0.5
Hand Tap, re-thread the hole.
The problem will gone !
