A Few Notes on the 66-77 Bronco Close Ratio V8 Power Steering Conversion Kit
Phasing keeps the forks of the yokes closest to each other in line and parallel to the center line of the shaft to avoid binding.
Always use the minimum angle when designing your system.
Never weld a universal joint. Welding reduces the strength of the metal and can belt the needle bearing seal.
Set screws are supplied on all splined and dd u joints.
Universal joint warranty disclaimer
Due to the performance and the custom use of this product, Tom’s Bronco Parts makes no
warranty expressed or implied, oral or written to the purchaser, regarding safety, fit, merchantability or length of service.
We do not recommend this product be welded. Welding can reduce the strength, the metal and/or melt the needle bearing seal. The installer of this product understands that choosing to weld the material is at your own risk.
Important: Buffing creates a very attractive finish in a matter of minutes. However, it is very important that the caps not be buffed on or near. The seal cannot be heated by the buffing or it will destroy the joint.
