Drivetrain & Differential Repair
From CV axles to differentials and transfer cases, we keep power getting to the ground, which matters when the roads turn to snow and mud.
Quick answer
What are signs of differential or drivetrain trouble?
Listen for whining that changes with speed, clunking when shifting or turning, vibration, or grease leaking from an axle. On 4x4s, trouble engaging four-wheel drive points to the transfer case. We diagnose the driveline and fix it before a small noise becomes a tow.
What's included
- Differential service and gear/bearing repair
- CV axle, U-joint, and driveshaft work
- Transfer case and 4WD diagnosis
- Fluid service for diffs and transfer cases

Built for the Yampa Valley
Four-wheel drive is not optional here, it is how you get to work and back. We keep ranch trucks and 4x4s pulling through snow, mud, and backcountry roads.

Frequently asked questions
Could be the transfer case, actuator, front axle engagement, or an electrical control issue. We diagnose the system to fix the real cause, not just reset a light.
Typically every 30,000 to 60,000 miles, sooner if you tow heavy or wade through water. We check it during service.
