axle bearings, need help

If you are running stock brakes, a stock housing and stock axles with (MO-400/ST-400) SNAP-RING style Green bearings, you do NOT need to remove the thrust block.

If you are using first generation (RP-400/Mopar Performance) Green bearings with the crimped-on retainer, you must remove the thrust block.

In addition, poorly designed rear disc brake kits such as Wilwood require thrust block removal.
