This video demonstrates me rotating a wheel/axle back and forth. It almost bounces when changing direction by hand.
I have recently swapped over to an m98 t2 differential in my 2004 is300. Along with this, I replaced the stock diff bushings with superpro polyurethane. The issue at hand is that upon changing from acceleration to coasting there is a thud coming from the rear end and can be felt dependent on how smooth I transition between coast and drive. I believe this is caused by an excessive amount of backlash. I have checked the U joints and drive shaft, the pinion gear seems fine as well, with little to no play there.
Any suggestions or resources on how to solve an issue like this would be greatly appreciated.
