The TORX bolt is a critical component that fastens the U-joint strap to the axle or transmission flange. If you hear metallic knocking, "clanking" or feel strong vibrations from the drivetrain, it may indicate a loose or broken bolt. Ignoring this problem leads to the U-joint bearing cap falling out, which results in its destruction and severe propshaft vibration. In an extreme case, the propshaft can detach, which can damage the gearbox and poses a serious safety risk.

The accuracy and quality of materials guarantee long and trouble-free use without the need for frequent replacement.
The bolt is fully adapted to work with original flanges and straps, ensuring a consistent and safe repair.
The GX-AFTER brand is a proven and safe alternative that offers quality comparable to original parts at a much better price.
Bolts and straps are single-use items. Always replace them as a complete kit to ensure even and secure clamping force.
Tighten the bolts to the manufacturer's recommended torque. Insufficient torque risks loosening, while excessive torque can cause the bolt to shear.
Before installing new bolts, clean the threaded holes in the flange from rust and dirt to ensure a correct torque reading.
A loose bolt is often caused by a worn U-joint. While replacing, inspect its condition and replace if necessary, lubricating with HYPTRON grease.
Answer: Yes, it's very likely. Loose bolts and straps cause the U-joint to run off-center, which generates huge vibrations. You should stop work immediately and carry out repairs.
Question: Why can't I reuse the old bolts?Answer: These bolts are designed to stretch slightly when torqued to specification, which ensures a secure connection. Once removed, they lose this property and reusing them risks them breaking or coming loose.
Question: What is the correct torque for these bolts?Answer: The tightening torque is critical and varies depending on the axle and machine type. It must be checked in the service manual. Incorrect torque is the most common cause of damage.
