With the MA70 Supra being a 30 year old car it's a good idea to replace all worn suspension joints especially if upgrades have been made to other suspension components. The Supra's Rear Knuckle Bearing performs the important function of misalignment at the Rear Lower Control Arm Outboard Mounting Point due to Toe changes in the Rear Suspension. 

We've designed our Rear Knuckle Bearings to be easy to install and rebuildable on the car.
