I am getting a shutter on acceleration, I have read in another post it is because my truck is lifted and the previous owner did not do it correctly. So I am going back and fixing all the issues. From what I have read the shutter is because the drive shaft is no longer at the correct angle, so I need to shim it. From the other thread a poster stated that he "thought" that it need to be a 1/4 inch for every inch of lift. I measured the total lift of the blocks and it measures 5 inches. It looks like the PO stacked a 3" block under the factory 2" block (which I know if a no no and am going to fix that as well). Is 1/4 inch per the correct drop for the shim? So I should just find a machine shop and have them make me a 3/4" square block to put under the carrier bearing support?
I would put some traction bars on the truck also, anytime you have a lift you pretty much need to get traction bars.
That is going to be my fix for the stacked blocks. Going to invest in some 5" PMF traction blocks.
Thanks for the reply to my post. Just reading that the shim will only solve high speed vibration and not the vibration on acceleration. That is caused by axle wrap.
How and what kind of grease would one use? I crawled under and I did not see a grease fitting or anything. I could see the splines, just put some grease in there?

Thanks in advance
There is a black rubber boot covering the splines , just buy some metal replacement fasteners to replace the plastic ones holding it now, remove the boot and slather any type of high temp grease on it. Be very generous with the grease. You need to pull the spline out for the best results.
Oh!... I have that under there. I thought was I was looking for was inside the support on the left of the picture. Your looks like mine does. Perfect! Thanks again for the help. I will stop at the auto part store and pick some up.
