Dorman 686-423 Front Left Loaded Knuckle
Features:
- Saves hours – eliminates the possibility of extended time spent wrestling with individual corroded components
- Simpler solution – no need for hydraulic press to perform complete bearing repair, making replacement faster and more predictable for both professionals and DIYers
- Quality engineering – designed in the United States and backed by a century of automotive aftermarket experience
Fixing a worn wheel bearing would traditionally require a difficult procedure using a hydraulic press, or purchasing multiple components. This Dorman OE FIX loaded knuckle includes all critical components already assembled for a fast, simple, safe install. For repair shops, that makes it less likely that you will have a vehicle stuck in the service bay. For vehicle owners, that makes this formerly complex job requiring special equipment much easier.
