2009 w900l vibration

I've saw u joints being match marked so they are put back the exact way they came off, to prevent possible vibrations.

 

Your angles from factory are as follows... 2 degree engine slant, 3.5 degee forward axle, 9.5 degree rear axle. All angles are in reference to frame angle. Engine/ trans angle is easiest to measure on oil pan or PTO cover. Axles are measured on housing between center section and brake spider. The angles you are trying cancel each other out under 1 degree. Your current numbers give you 1deg @ tranny, 1.0 deg @ center bearing and 0 deg @ power divider. Your two angles are 1 deg different and causing angles not to cancel each other. Try moving front axle to factory specs.

 

Oh man.

I give up.

 

3.5 on intermediate drive, 9.5 on rear drive. That is with air ride @ proper ride height.

 

When I looked up your truck, I noticed you have the AG460 so your ride height is 10.5". Also check your spacers on front upper torque rod, should be 8MM on your truck. Sometimes guys replace the rods and don't mark and put spacers back in proper place. Back ones are 13MM. Included manual so you can check ride height.

 

You can spec them that way so you have more suspension travel. This thing was speced for getting off road some with 4.11 gears and 11r24.5 tires. What was your ride height @?
