Im getting worried because my rear axle looks tipped pretty good at dead on. Want the lube to be able to get to the pinion bearing assembly. Its now started leaking out of the rubber drain plug since ive tipped it so much. But man do i absolutely love the clearance and look of not seeing the drop bars there. It also puts the shifter back in the stock location so you can fit a drink in the front cup holder without nailing your fingers on it while shifting into 2nd. Maybe i will try tipping it a tad more sometime.
interesting! have you ruled out that it isn't your front shaft causing vibs?
also, i know on my rear drive shaft, (coast driveline)that there are specific little slots where my u-joint is located and if they don't mesh properly, it would for sure have caused vibrations...
