Differential Repair in Cheyenne, Wyoming
Honesty & Quality
Differential and axle work is a specialty of its own — setting up a ring and pinion takes patience, precision measurement, and experience reading a gear pattern, which is why plenty of general shops won't touch it. TDC Automotive does it all: diagnosis, fluid service, leak and seal repair, full rebuilds, re-gearing, and air locker installation.
Whether it's a howl that grows with speed, a clunk on throttle changes, a leaking axle seal soaking your brakes, or the wrong gearing strangling a truck on 37s, the differential work here is measured, set up to spec, and pattern-checked before it goes back on the road.

Differential Diagnostics
Differential problems talk to you: a howl or whine that changes between acceleration and coast points at the ring and pinion, a growl that follows road speed suggests carrier bearings, a clunk when you get on or off the throttle means excessive backlash or worn spider gears, and vibration under load can be pinion bearings or a U-joint pretending to be an axle problem..

Gear oil is the only thing standing between your ring and pinion and a very expensive noise, and towing runs axle temperatures high enough to break fluid down well before the odometer says it's time.
Learn more →Differential Re-Gearing
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.
Learn more →Differential Rebuild
A differential rebuild replaces everything that wears — carrier and pinion bearings, seals, and the ring and pinion or spider gears when they're damaged — and returns the axle to factory-spec quiet and strength.
Learn more →Differential Leaks & Axle Seals
Differential leaks come from a few usual suspects: the pinion seal up front, axle shaft seals at the wheel ends, and the cover gasket.
Learn more →Air Locker Installation
An air locker gives you a true selectable locking differential — open and streetable on the highway, then 100% locked at the flip of a switch when you're in snow, mud, or off-camber ranch two-track where one spinning tire means walking.

- 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.
