Is your carrier bearing shimmed properly?

[SynysterHD]

I have the same problem. My carrier bearing is shimmed very close to perfect, but I was told that my problem may go away with one more shim.??? I was also told that a one piece drive shaft will knock out that problem... I'm gonna try the shim first cause its WAY cheaper! I priced a one piece shaft @ around $400...

its dropped about 2.5" i have had no problems at all until today when i put a new carrier bearing on it.

Yeah replaced them a bout 6 months ago. i took the bracket loose and it doesn't seem to slide very easy and was hard to get it centered back up to bolt it back up. kept wanting to go to the side

one more question. do the 1st and 2nd part of the drive shaft need to be at the same angle? because from what i can tell they're in line with each other almost looks like a one piece.

It dosen't matter as long as the angles cancel each other out. You would need a protractor to check them all.

[JD_MILLS]

can you go a little more in depth with that? and i dont get how putting a new bearing in can cause that.

Maybe your old bearing was letting the propshaft sag and the driveline angle was correct. Now your new bearing picked up the shaft a bit, causing your issue.
