🔧 Tech Notes
Sold as a pair (2 caps) – four required per vehicle (two per side)
To Access the kingpin bearing race for removal, you will need to hammer out the existing grease caps that sit on the underside of the race. Doing that will cause damage to the existing cap and will then require new ones to be fitted.
❓PLEASE READ!!!
- NOTE THE DIRECTION OF THE PREVIOUS GREASE CAP FOR CORRECT FITTING.
🧰 Why Replace These?
Many Patrol swivel hub kits omit these caps, yet they are essential for sealing the hub cavity. Reusing old caps can lead to oil leaks and premature bearing failure. These quality units ensure:
Correct press-fit tolerance
Long-term sealing integrity
Reliable protection from contamination
