Knuckle Joint - Suspension (Front to 1990 & All Rear)
Knuckle Joint - Suspension (Front to 1990 & All Rear)
Suspension knuckle joint that fits the front of all models up to 1990 and the rear of all models. They are complete with the knuckle, nylon cup 21A423 and rubber boot 21A425.
If your suspension has dropped suddenly or you have loud squeaking or knocking noise during suspension movement, then these knuckles are one of the first things to check. If left unchecked, the knuckle can wear through the nylon cup into the suspension arm and ruin the casting that supports it. Much cheaper to replace than changing the arms.
