Driveline vibes after zero rate install

[BEEBOB]

Just install rear zero rate from ORD. Pinion looks to be even with transfer case. Looks like maybe more drive shaft is hanging out of transfer case. How much shaft should be in the transfer case. Gonna pull shaft tomorrow and check u joints.
Don't really want to drop transfer case, but will if that's the fix.
What have you guys ran into. Did not think a 1 inch lift would do this.

Yes a have searched,

Thank you

Shim the pinion about 1* below directly at the tcase output.

Also it would help to know what you're working on and how much lift it already had prior to adding the zero rate.

Yep, one inch lift won't affect anything if it is stock height. But if it is not, I am inclined to think that it is extended too far out.

Added zero rate to stock 87 k5 to level it out

 

[BEEBOB]

I installed the zero rate in center pin hole(no axle movement) should I have moved the axle forward 1 inch?

 

[Stomis]

You should not have an issue from that. Something was wrong else where that the small amount of lift exaggerated.

Found it guys. The rear ujoints were toast. Pretty sure it's supposed to have needle bearings instead of dust.
Thanks for y
The fast responses.

LOL! Needle bearings are overrated

Yeah less friction equals more horsepower right.
