Symptoms
Snapped rear axle-flange studs.
The fix, step by step
- The usual cause is a warped axle flange face from hammering on the shaft to free the cone washers.
- That loads one stud at a time until they break.
- Free the cone washers by tapping the stud ends with a brass drift, or use a small screwdriver in the washer slot.
- Have a warped flange refaced on a lathe so it sits square.
- Upgrading from 8 mm to 10 mm studs at the same time is a common choice.
