Vibrations continue
 
I've got some wicked howling vibrations forming lately.

My SOA has a super shorty JB Conversions SYE, a CV driveshaft, 1" Lifted motor mounts, 1.5" T-Case drop. Even after all of this, just driving down the road, it howls. The faster I go, the worse the vibration. Almost no vibration at idle (a bit in the dash, but nothing serious) but as soon as I start rolling, it starts.

What can I do to fix this? Shave the CV joint a bit to allow more travel? Move my axle back 6" using XJ springs? I really thought I'd be past all of this with all I've put into it.

I would guess either you have bad u joints or the angle is wrong on your rear end.one of my yj's has a soa and other than angling the rear end the only mod is 1 1/4 inch transfer case drop.it has no vibration

harley - I'm using brand new spicer greasable joints. They look like they're in good space. The rearend is angled to point directly at the SYE and it has an anti-wrap bar to keep it from pulling upward.

I think I'm gonna throw my gopro under the Jeep and take a few laps to see if I can see what is binding up.

that's one of those things I just have to tinker with..might try getting an angled shim and trying it both ways to see if it makes a difference
