Symptoms
Camber you can't align out, odd tire wear or changed steering on a JK running 35s or bigger. Quadratec warns that heavy tires and hard use can bend the axle C's where the ball joints sit.
The fix, step by step
- Have the axle checked first: a bent C needs straightening or a replacement housing before any gusset goes on.
- On a straight axle, strip the paint and coatings where the gussets and truss go and tack them in place.
- Weld in short alternating beads to limit heat distortion, then let it cool and coat it.
- Many owners do it with the axle out of the Jeep, along with the ball joints.
