

Be careful not to damage the ball joint boot when installing the knuckle.  



Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of 
the ball joint pin, the connecting hole, and the threaded section and mating surface of the castle nut. 



Torque the castle nut to the lower torque specification, then tighten it only far enough to align the 
slot with the ball joint pin hole. Do not align the castle nut by loosening it.  



Before installing the wheel, clean the mating surfaces of the brake disc/drum and the inside of the 
wheel.  



Check the wheel alignment, and adjust it if necessary (see WHEEL ALIGNMENT ).
