Ok,
1)
I check the rear diff. It will "spin" free: applying force in one wheel, and with other wheel "locked" and reverse.
Using a jack, manually spinning the "joint" (where the rear prop connects)in differential, both wheels move, if I block one wheel, the other continue the movement....
I think the rear diff is ok, right?
2)
Do the same in front, same results
3)
Try explaining to my friend (where the RR is, and who is helping me), the VCU "test", we try in the gearbox, locking one "shaft" and we apply force in the opposite "shaft"......... we can slowly move....but with some "force". we try in another direction, same thing.
(here came the photo that I took).
Remember, if I "spin" one "shaft" the other will spin freely.
What you guys think, about all that have tested.
Do I have or not a VCU problem???
Or it´s not conclusive??
What I sould do / test now, to check why my rear wheels did not "spin" in the mot?
Thanks
