Installed lift
So me and a friend mechanic installed my lift today and now when i take off there is a vibration .. only for a few seconds then it gos away so i think i need to buy some of those wedges to correct the pinion angle. Does anyone no the stock pinion angle ?

Block wedges are helpfull only if your pinion angles are off.
If your angles to eachother are complementary, then you shoudln't have to change ..
wait hes got a split..
yea, if you lift with a dual drive shaft (whateverthosedumbthingsarecalledihavn'thadenoughc offeetothinkstrait) Then you need to move the carrier down, like beggs suggested, because the angle is greater then 180 total.
I think its 180 for the carrier setup..

If you had the blocks that are thicker on one side you don't need the shims, they are angled blocks. And yes, the thicker side goes towards the rear of the truck. Has the truck been aligned yet? That is something to have done first too before you go buying new parts. Just my $.02

no it hasn't been aligned yet mabey tommorow .but if i have to put some shims between the rear springs and the axle then i would have to re-align it so i might weight to get the vibration dealt with first ... tjbeggs would shimming the carrier bearing help ? cause if the pinion angles wrong doesn't it have to be fixed ? or can shimming the carrier bearing cure the vibration ? if i shim it should i just put washer between the carrier bearing and were it mounts ?

Well i guess what i meant to ask also was are you sure it's coming from the drive line? I have had front ends so out of wack after a lift that they cause a vibration when going slow or starting off. What kit did you buy? If it has the angled rear blocks don't shim it more, if the driveshaft is the problem, drop the carrier bearing like everyone is saying.

You need to adjust the carrier if you add a lift.
changing your pinion angle might cause more problems if your carrier is misplaced.
Pinion angle shoudln't be much of an issue. Adjusting the pinion angle to much causes it to not lubricate properly.
A carrier drive shaft setup has to have a certian setup in the angles, otherwise it vibrates.
lowering the carrier will adjust the pinion Ujoint angle.
Your actually going to have to phsyically lower the carrier a bit.
SRQ SCION, if he lifted, he screwed up his 2 piece drive shaft's complementary angles, so he is going to have some noise and shudder.
But yes, you are correct, a lift will make it easier for things to shudder.
Does anyone know the 2 piece drive shaft angle total? is it 180?
one piece is complementary angles, and 2 piece yes, is 180.
complementary will equal 90.

I don't worry about measuring angles. just drop the carrier bearing a half inch and see what happens.
to masterc16 it would be best to use something solid like a peice of flat stock. washers will work for temporary diagnostic work. then jsut get the same thickness flat stock with holes drilled in it.

ok guys i got it to an anligment shop, casters out, cambers out both side ....but they say mabey when the springs wear in abit the camber will be better .As for caster there thinking about shiming front springs . And for the vibration im going to drop the carrier tonight .. i'll let you know what happeneds with that ... I must say im not very happy with lifting my truck , Its a rough counrty lift ..has anyone used this lift or any other 4inch lift and had these problems ?

does the kit use drop brackets for the pivots of the front axle? if it didn't it should have! and if it didn't you will need to get some. the caster is adjustable with the camber bushings. they are actually camber/caster bushings.
