I recently lifted my truck more, and now have a vibe from about 4-9mph when accelerating. Or even slightly rolling at those speeds and in reverse. I have Bilstein 5100's all around, the fronts are set at 2.5" and I have the rear Toyota TSB, and then the 1.5" Toytec AAL for the TSB. How can I eliminate this vibe? When I put it into 4Hi, the vibe is gone, so is it a rear driveshaft problem? Would the carrier bearing drop kit and/or axle shims(what degree?) work? Or could I just take it to a dealer an see if they will do a driveshaft TSB that I think I read about.
My rear wheel well is 39" from the ground(in the center) and the front is about 37". Could I get the toytec 3/4" lift spacers on top of the front 5100's to make it more level, and would that help the vibe or worsen it or do nothing? Because I want the front lifted like one more inch, but also wanna eliminate these vibes.
Thanks in advance
