Vp currie axle diff grinding while setting up

I had the same problem, and I thought it was because of the gripfab locker. After some trial and error it wound up being the bearing tabs in the housing. I ground a very little off both sides and it was good to go. Now I dont have to mess with sanding bearings.
 
while i dont question that removing some of the tab material works, it seems like it would move the diff a little bit from the axle centerline...

right? the diff fits and spins freely with the axle shafts without a pinion installed iirc.

Yeah, that's what I can't quite wrap my head around. Without a pinion mine spun completely free.. With pinion installed it practically locks it up solid when you tighten locker bearing caps. The only logical thing I get is the pinion is too far in the housing and needs some more play in the housing so we can shim it closer ourselves.
 
Call vp, I had the same problem, they'll take good care of you

You don't want to shim the pinion closer it will bind things more. You need to sand down the inner pinion bushing/bearing like Harley said. Basically you have zero or negative backlash and it will get worse as you drive the Wraith just like in 1:1.

You misunderstood what I said. I was talking hypothetically if VP changed the inner bearing seat for the pinion so it wouldn't be so tight. THEN, the end user (us) could shim the pinion for proper mesh instead of having to sand bearings/bushings just to keep the assembly from binding.
