Driveline vibration?

[GunMetalGrey]

Anyone else have vibrations in their driveline?
Mine seems to vibrate a bit in lower gears at high rpms, I think my csb may be slightly out of line, think that would do it?

worn U joints. Then may appear good but when they are under the load allow too much sloppiness

i too have these vibrations. like decent acceleration in 1st,2nd, maybe 3rd at like 2.5k rpm

None here. How much did you shim the motor?

[GunMetalGrey]

One washer on the passenger's side at this point, did it without the motor shimmed.
Going to straighten the csb tomorrow.

Last time when I would tighten the bolts for the csb it would twist the mount on me, would new washers take care of that? They have a bit of surface rust, so I feel like that is grabbing onto the mount plate of the bearing and twisting it when it gets tight.
Anyone else run into that problem?

Check if all the bolts on the rear end are properly tightened. Mine was vibrating like mad, turned out that one of the bolts that mounts diff to sub-frame was loose.

[GunMetalGrey]

Yeah, that was a plan as well.
It only takes one little thing to be loose for some vibrations lol.
I will work at it and keep you updated.

I'm getting some driveline vibration with a swap car that I built... Happens in first gear only from like 1.5k to 3k...

Car has an S50 mated to a getrag 260. It only happens when I accelerate from a start quickly... if I get moving slowly it doesn't really happen.

I get vibrations shifting down into 3rd (low DD rpms) and rarely down into 2nd.
No idea what it is.
