ok went for test drive today.

Pulled away from the house and up the street...reached 45mph, alls smooth.

Then i put on the brakes, felt like it was binding/catching. Vibrating the stick shift like crazy, not popping out of gear though.

My thoughts...my pinion angle is too low now. When the vehicle slows/brakes the pinion turns down causing binding.

Anyones thoughts.

To recap, i've got 3/4 in trans case drop and no shims. I'm thinking i should have slowed my roll a little bit and waited on ya'lls response, i think i'll be dropping the rear u-bolts again to replace the shims.

Ok y'alls turn.

Thanks!!

Agreed. When troubleshooting you never change more than one variable at a time.

yoke still looks like not in far enough. maybe put tape around it where it meets the TC then pull it out to see just how much of it is going in.

Ok, so can someone help out a rookie here. How does a mml help to correct the rear driveshaft angle? Wouldn't that just raise the t-case also?

Okay with the 3 degree shams in place it is significantly better. However on very hard braking I still get the heavy rattle or binding. Do I need bigger shims? Can I stack shims?

If you got that much play you need to double check how tight you got your ubolts. Spring under should not rotate too much if everything is fastened down all the way. Vibrations should mainly happen under power.

They're torqued to 90 ft/lb as per the Rancho u bolt instructions. I'm just speculating as to what is going on.

What I know.
With a 3/4 trans case drop and no shims I have a nice ride with no vibes. On braking I have quiet a racket. Stick bounces all over place but not out of gear.

With a 3/4 trans case drop and 3 degree shims I have a nice ride with no vibes. On light branding nothing, on heavy braking I get the racket again, not nearly as bad.

I'm currently running it with no shocks as I will need to measure and order new ones. I don't think that has anything to do with it but figured I'd make it known

Ubolts are torqued first to 60 ft/lbs then 75 then 90.

I'm thinking ill try lowering the tc a bit more to see If that changes anything.

I know I have a tc drop from a 4" lift kit and it is 1.5" drop. Kit also came with 3 degree shims. That was a rough country lift. So maybe 3/4 just isn't enough.

agreed. judging by pics the pinion doesnt look too bad. T-case still looks steep. measurements would help.
