Terrible noise after SYE

[tompatjr]

Well, Yesterday I took off my Degree Shims and went for a test to the Freeway and the Vid is almost gone, I can barely feel it now.
I'm thinking about turning the blocks that I have backwards to point the pinion even lower.
Opinions?
Ahh, Thanks for the great advice guys

Experiment some with it to fine tune it would be a good idea. You'll get it right, soon. More importantly you know the cause of the vibration.

 

[O.D.]

I have a RE 4.5" lift no shims, sye and no problems.

Are you running stock shackle too then? If not then you must mention that as extanded shackles rotate the pinion up.

I don't have 4.5" of lift, I have 6". And I do have extended shackles, I have the RE 1.5" ones.

it looks like you pinion is to high. Your pinion angle should be within 3 degrees of your driveshaft angle. you might get away with maybe a 2 degree shim.

I'm going to install my blocks looking back. The blocks that I have have a little degree, wich is keeping the pinion a little too high. I'm going to try this and see what happens.

I bought the 3" RE lift, their SYE hack n tap, and their DS. Had similar problem until having the shaft balanced and checked for runout. It was pretty far off (both parameters) and vibes were reduced to a minimum after the work.

Relifted (that a word?) to 4.5" and am getting the Woods DS and yolk type SYE. Am thinking I won't have to get balance and runout corrected on the Woods shaft.

My problem wasn't the DS not balanced, I removed the degree shims and the vib is almost gone, I can barely feel it at 75+Mph wich is a speed that I don't normally drive at.
