I'm lifted at 5"s I have an sye with a grand cherokee front cv shaft in the rear.
My opinion angle is perfrct with 4 degree shims...however even with my tcase drop in I still get very little vibes...if I take the tcase drop out they get much worse. The ujoints and centering ball on the shaft seem to be in good shape. And I still get vibes without my front shaft in..
What do I do? I'm thinking of brining the shaft to a shop and having them check it out and rebalance it.

Don't waste your time with a shop, align it yourself with a tape measure and a pipe wrench. 1/16" total difference between front of the tire and rear. Look up how to do an alignment, it's quite simple.

Then don't lift it 5" til you can afford to do it right. Be patient and save up and get the parts to do it once and correct. You may not get vibes (though at that height it's highly unlikely) but if you get too much down travel and your rear shaft falls off it's gonna suck.

Im worried about the same thing I need 5in lift up front to get mine level. Then again may go with a 5.5" set up and just add a shackle to the back for the extra half inch

Alright lets bring back the topic of tire pressure... we just got new wheels and a pair of new tires. I asked the guy what psi he was going to put in em. He said about 45, to which my dad agreed.
From what I understand, and have read on here, is that you'll want to run less pressure than reccommended in the door because they are larger tires. My dad's arguement was that in order to get the larger tire to behave the way the smaller tire does you need to run a higher than stated pressure to make up for the difference in volume. He also said that a larger tire at the same pressure as a smaller tire will flex and distort more going around turns, thus you need more pressure.
My thinking was this: the psi on the inside of the door is for a set tire size, thus a specific amount of air and pressure at each tire to support the weight of the vehicle. Because the size of the tire increases, a smaller psi is needed to achieve the same amount of air used to support the weight of the vehicle.
Thoughts? Links? Science?
