Symptoms
Wander, a steering wheel that won't center, clunks over bumps and uneven tire wear. Lifted trucks and cranked torsion bars make it worse: one owner says parts wore out 'five times faster'.
The fix, step by step
- Separate the tie-rod ends, pitman arm and idler arm with a puller, count the turns on the tie-rod sleeves to keep a rough toe setting, and replace the worn parts.
- Owners recommend heavier tie rods and an idler and pitman support kit if you run 37s.
- Grease every fitting afterwards.
- The idler support's fitting can't be reached without removing it, so a grease-relocation kit helps.
- Get the truck aligned.
