Differential Re-Gearing
Differential Repair — Cheyenne, WY
Put 35s or 37s on a truck and you've effectively changed its axle ratio — the engine lugs below its powerband, the transmission hunts on the highway, towing suffers and so does fuel economy. Re-gearing swaps the ring and pinion to a ratio that puts the drivetrain back where the factory intended, or optimizes it for how you actually use the truck.
Trevor sets up gears the right way: proper pinion depth, bearing preload, backlash to spec, and a verified contact pattern before the cover goes on. Both axles on a 4x4 get matched ratios, and it's the natural time to add a locker if traction is on the wish list.
What's Included
- Ratio selection matched to tire size and use
- Front and rear re-gears on 4x4s, ratios matched
- Pinion depth, preload and backlash set to spec
- Contact pattern verified before reassembly
- Locker installation at the same time saves money
Axle Work Done to Spec
- Diagnose by ear and evidence
Howl, whine, clunk or vibration gets road-verified, then confirmed by inspecting the gears, pattern and bearings.
- Measure everything
Backlash, preload, and pattern — differential setup is measurement work, not assembly work.
- Quality parts
Gears, bearings and install kits from names that hold up under load.
- Pattern-check and test
The final gear pattern gets verified and the truck road-tested before delivery.
