So, I read most of the threads about driveline angles... I SHOULD be vibe free. I have had 3 other jeeps with similar lifts I put together without vibes.
So...
I have an 05 TJ with the NSG 6 speed
OME HD lift
Extended LCAs (Synergy)
Adjustable UCAs (Synergy)
1” MML/BL
Rear Axle pointed up 9 degrees
Transfer case pointed down 9 degrees
Stock Driveshaft is 18 degrees
Everything tells me that this should be just fine, but getting that nice high frequency buzz around 60mph.
ODDLY, only while accelerating and coasting, deceleration seems to be good.
Rear bushings are super tight DDB (polyurethane), so I didn’t feel the need to adjust for axle movement when engine torque is applied ...
The only thing I suspect is that the working angle of 9 degrees is excessive, the TEXTBOOK answer is 3 degrees, but is 9 degrees working angle TOO MUCH ???
Thanks!
