Just installed a 3 inch lift from toytec and now have a vibration at all speeds. Seems to be coming from driveshaft. U-Joints are good but was wondering if there is a kit to lower center bearing to reduce driveshaft angle on my 99 Tacoma 4x4. Any help would be greatly appreciated.

 

What kind of 3" lift?

:wabbit2:

 

could be your cv's. did you install the 1'' drop on the front diff? if your vibration is from the cv's then the drop spacers will help. did you get the front end aligned after the lift?

 

Sorry it took so long for the reply.

I put on the front spacers with the diff. drop kit, add-a-leaf in the rear with extended rear shocks. New front struts. Vibration was like I was riding on railroad tracks. I did some research and foud out the angle of the driveshaft might me the issue. I fabbed some spacers and this helped some but not completely. I just replaced the carrier bearing and this helped a little more. Is there a specific width of spacer I should be using? All u-joints are good. I have varied the spacers with some luck.

 

Measure the angles and you'll know for sure:

As noted, you are looking at approx. 1* of shim per inch of lift, but best to measure and find out the exact number.

And generally shimming the center support bearing is not the way to go as while you are improving the angle at the back of the CSB, you are making the angle at the front worse.

 

Excellent.

This is what I am looking for! Thank you. You are dead on with the measurements as well. 3* will take care of it. I will let you know how this works when I get them in there.
