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
Dorman supplies standard replacement suspension hardware built to match the listed application details for proper service fitment.
