    I need to shim my rear like 6 more degrees to have the perfect driveline angle. Right now I have 4 degree shims. I have read that someone took blocks and had them cut to the desired angle. Could I stack shims? I think to have the spring perches welded would cost too much money. I think the small amount of vibration is the reason why my t-case started leaking out the rear seal.

    Dont stack shims!!!!! They will walk out from under each other. Have you considered doing a shackle flip and throwing the blocks away? That would help your pinion angle alot. 10 degrees of shim sounds like an awful lot I have a 6" lift any only had 3 degree shims in it. You could also ask a machine shop to make you some shims cut to your specs.

    I thought I was wrong once,
    but I was mistaken

    No, I have 6 inch rear springs. I was referring to cutting a block down to act as a shim. i will ask a machine shop when i get a chance. yeah, it is weird i still am getting some vibration ( though not much ).

    Before spending the money, drop you transfer case down one inch and see if it goes away. If so then spend the money, you might find out it is something else causing it.

    Already did that. dropped it one inch. I mean it is barely noticeable but still there. maybe a 6 degree shim would do...

    The reason I believe he needs that much angle is that he is trying to rotate the pinion back up for his new c/v shaft and not down for a regular shaft. You are right about the shackle flip and 2" to 3" springs would probably help get him close enough to just use a small degree shim if any with the c/v shaft. Just my $.02

    See Ya,
