Steering Knuckles
Repairing worn wheel bearings has traditionally been a tough job, requiring a hydraulic press and lots of patience. That’s why Dorman developed exclusive loaded knuckles that come pre-pressed and ready for installation right out of the box, eliminating the hassle that used to come with these repairs. Dorman also offers bare knuckles, without any additional equipment, for knuckles bent in collisions.
