When raising the suspension on a Patrol, it is often required to install offset castor bushes to correct the alignment. This is because raising the front suspension rotates the front diff forward. Installing these Drivetech 4x4, 2 degree castor bushes will rotate the diff back into alignment and correct the castor.
It is important to maintain the correct castor setting to ensure the vehicle track straight at high speed. Without them, the vehicle may wander and feel unstable.
