anyone got an idea of how to fix the driveline vibration that occurs now that ive lifted my tacoma 3"....Its not really bad but definately noticable and I dont want to mess up other things from vibrations.

its a spacer front with an aal rear.

??? thanks jamie

The only option is to run a diff drop spacer.

Well, you could grease the zerks in your drive shaft and u-joints and see if that works. Did you get it aligned after your spacer installation? Check the torque on your lugs, should be about 85 ft/lbs.

I'm assuming jmansouri has 4WD. You, humanoid, have 2WD. 4WD vehicles have axles in the front that when lifted near 3" will cause vibration due to the angles of the axle shafts. The only way to compensate this (without doing an $1,100 manual hub conversion) is using my previous suggestion.

I have had an alignment and my tires are balanced, lugs tight. does the front driveshaft spin all the time? I thought it didnt spin when not in 4 wheel. I did install the diff drop in the front so I thought it would be ok. Someone recommended rear axle shims - 3 degrees. I will it try and report back. thanks!

I'd lean towards the rear pinion angle, and there fore the universal joint, as the problem. Tapered shims between the spring and the axle perches should help cure the vibration and as a side benefit, it will free up some drag on your drive train. A u-joint running at an extreme angle will soak up power and slow you down.
