Our 4×4 Repair Services

We offer a full suite of 4×4 repair and maintenance services designed specifically for trucks, Jeeps, and SUVs that see daily miles, rugged trails, big tires, and lifted suspension.

Suspension & Steering Repair

Your suspension absorbs impact, controls articulation, and keeps your tires in contact with the terrain. We diagnose and repair:

  • Worn shocks and struts
  • Ball joint and control arm wear
  • Track bar and sway bar link replacement
  • Steering gear box play, tie rod and drag link wear

Our crew ensures your lifting components work together, restoring smooth performance and predictable handling.


Diagnostics & Check Engine Repair

Modern 4×4 vehicles have complex computers and sensor systems that require precise diagnostics. Our technicians use advanced tools like Snap-On and OEM-grade scan tools to accurately diagnose:

  • Check Engine warnings
  • ABS and traction control faults
  • Active safety sensor calibrations
  • Transmission electronic codes

We pinpoint the real issue — not just the symptom — and communicate repair options with clarity and honesty.


Drivetrain, Transmission & Differential Service

Power delivery meets the pavement — or dirt — through your drivetrain. Whether it’s a leaking axle seal, differential noise, or transmission shifting issues, our team evaluates and repairs:

  • Differential rebuilds and seal replacement
  • Transfer case service
  • Driveshaft balancing and U-joint replacement
  • Clutch and transmission repairs

We help keep your 4×4 running smooth from transfer case to wheel hubs.


Brake System Inspection & Repair

Off-road driving, heavy loads, and mountain terrain place additional demands on your braking system. We handle:

  • Pad and rotor replacement
  • Caliper diagnosis and service
  • Parking brake inspection
  • Brake system flushing and fluid exchange
  • Brake upgrades to support other modification or driving habits (and locale...like I-70 and canyon roads)

You’ll feel confident stopping — whether you’re descending a mountain trail or navigating city traffic.


Alignment After Suspension & Lift Work

Once you install a lift kit or new suspension components, your alignment must be recalibrated. REV Outfitters offers precision 4×4 alignment services that correct toe, camber, and caster to optimize tire life, steering stability, and handling — even on lifted vehicles.


The REV Outfitters Difference

What sets our 4×4 repair shop in Colorado apart is our commitment to system-level expertise, honesty, and customer education. When you bring your vehicle to us, you’ll experience:

Transparent Communication

We explain issues in plain language, show inspection photos, and offer clear repair options — no guesswork, no pressure.

Skilled Technicians with Off-Road Passion

Our team doesn’t just fix vehicles — we build and drive them. That’s real world insight you won’t find at a typical repair shop.

Advanced Diagnostic Tools

We invest in professional-grade equipment designed to support complex 4×4 systems and modern vehicle computers.

Warranty Backed Service

Many of our repairs and replacements come with confidence-building warranties — because quality service should endure the miles.


Common Signs You Need 4×4 Repair

If you’ve noticed any of the following, it’s time for a professional evaluation:

  • Steering feels “loose” or wanders
  • Uneven or rapid tire wear
  • Strange noises under acceleration
  • ABS or traction lights stay on
  • Clunks or grinding over bumps
  • Vibration or shudder at highway speeds

Ignoring symptoms often leads to larger, more expensive problems down the road — especially on modified 4×4 rigs.


Our 4x4 repair shop techs in Johnstown and Boulder Colorado are highly trained to address customization and common issues like:

  • Mall crawler to rock crawler customization - we love it when our customers want to invest in their adventure and freedom!  We want to make you feel great and personalize your jeep so that it is unique to you and who you are.
  • Death wobble and steering wander - if you have experienced death wobble you know what it is and you never want to experience it again.   We guarantee that we will fix the issue.  See our death wobble blog for what death wobble is.
  • 4x4 Alignment - from stock to adjustable control arms and other major modifications. We rock with alignments!
  • Diagnostics - The dreaded check engine light or your jeep just isn't running like you think it should….we have the technology and skill to address your issues.
