Ok... so I lubed the crap out of my slip yolk and that seems to have made it much quieter? Did not hear it at all last night and this morning when I went to the store. Just one small one once. So still seems to be there.
All u-joints are very tight. No play with eachother. I can push the drive shaft up and kind of wiggle it around a little in the carrier bearing. 1/4" or so. From my research that seems normal?
My shocks are bad though. The bottom mount bushings are torn. The drivers side is worse and the shock isnt really centered in the mount anymore. Not sure thats what could be causing the noise, but it sure is time to replace! 160k on them.
Everything else bushing wise looked real good, no play in anything as far as I could tell.
Here is the drivers side bottom shock mount...
Not as bad, but still has a tear.
Going to pick up some 5100 Adjustable shocks here soon..
