Support Bearings
WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
Directly after the Polhem joints are the propeller shaft's support bearings, which are the single-row, permanently-lubricated groove ball bearing type. They are fitted in rubber bushings which in turn are fitted in brackets.
The brackets are bolted to the underside of the vehicle and their position is very precisely measured during vehicle manufacture. If the support bearing brackets are fitted incorrectly then vibration will occur.
