Product Overview
This Dorman 929-801 leaf spring axle U-bolt kit is built for rear suspension service where the leaf spring pack must be clamped securely to the axle housing. The steel U-bolts, fine threads, and standard replacement dimensions make it a direct service part for Ford F-150 rear suspension repairs and Lincoln Mark LT rear axle mounting applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Loose or weakened leaf spring-to-axle clamping
- Corrosion-related U-bolt replacement during suspension repair
- Rear suspension noise caused by worn mounting hardware
- Loss of proper axle-to-spring retention after service work
- Fitment issues when replacing damaged square-bend U-bolts on Ford F-150 or Lincoln Mark LT
Installation Notes
Verify leaf spring dimensions, inside length, inside width, thread diameter, and thread length before installation. Confirm rear square-bend application details for the specific Ford F-150 or Lincoln Mark LT model year. Replace hardware in accordance with the vehicle service procedure and torque specifications.
Quality Assurance
