Mini Suspension Knuckle Joint
If your suspension has dropped suddenly, or you have loud squeaking noise during suspension movement, then these knuckles are one of the first things you should check. If left unchecked, the knuckle can wear through the nylon cup, into the suspension arm, and ruin the casting that supports the knuckle joint.
Fits front and rear except later cars 1990 onwards that had a built in spacer for extra ride height clearance at the front
