Symptoms
A clunk from the rear under heavy load, such as towing up a hill, and a wandering feel in corners if the crack has grown.
The fix, step by step
- Unsealed's order: have the crack professionally welded, add chassis bracing straight away from someone who's very good with a MIG, then fit the GVM upgrade the truck should have had in the first place.
- After that, check the area at every service.
Tools & part numbers
- Welder and grinder (or a fab shop)
- bracing plates
- GVM-rated springs.
