Detailed Description

This Dorman leaf spring axle U-bolt kit is built to clamp the leaf spring assembly securely to the axle housing, helping maintain proper rear suspension location and clamping force. The 5/8 in fine-thread design, 13.5 in inside length, and 3.625 in inside width make it a direct-fit style solution for applications that match these dimensions, including rear suspension service on Ford F-150, Ford F-250, Ford F-250 HD, Ford F-350, and Ford F-350 Super Duty models listed in the fitment data. Dorman 929-769 is a practical choice when replacing worn, stretched, or corroded axle U-bolts during leaf spring service.

What It Helps Fix

• Loose leaf spring-to-axle clamping
• Corroded or fatigued U-bolts
• Rear suspension noise from worn mounting hardware
• Improper axle retention after leaf spring service
• Fitment issues when replacing damaged round-bend U-bolt hardware

Installation Notes and Tips

Verify leaf spring dimensions, axle tube size, thread diameter, and inside width before ordering. Match the rear application and note the round bend fitment details shown for the listed Ford trucks. Replace suspension hardware in pairs or as required by the service procedure, and torque fasteners to the vehicle manufacturer’s specification after the vehicle is at ride height.
