What Is Heavy Duty Truck Repair And Why Does Routine Maintenance Matter?
Heavy duty truck repair covers the work that keeps large commercial trucks and tow rigs operating safely and legally. Unlike standard auto repair, it involves frame-level repairs, heavy-duty axle and suspension systems, and specialized hydraulic and drivetrain components that most shops never touch.
At Quik Tow Repair, this is all we do. Whether you run one flatbed or a fleet of wreckers, routine maintenance and timely repairs are what keep downtime low, keep you compliant with FMCSA commercial vehicle regulations, and keep your revenue rolling. Our process is built around getting your truck diagnosed, quoted, and back on the road fast — with no surprises on the final bill.

Heavy Duty Truck Repair Services We Offer
Every repair listed below is performed in-house at our Pomona shop by technicians who work exclusively on heavy duty tow trucks and commercial rigs.
01Frame Repair & Straightening
Tow truck frames take punishment that standard commercial trucks never see — repeated heavy loads, winching stress, and off-road recoveries all take a toll. We repair bent, cracked, and twisted frames using professional frame straightening equipment specific to heavy commercial chassis.
- › Frame damage assessment
- › Hydraulic frame straightening
- › Frame crack welding & reinforcement
- › Post-repair alignment check
- › DOT compliance documentation
02Suspension System Repair
A failing suspension on a heavy duty tow truck doesn't just wear tires — it compromises the safety of every load you pick up. We rebuild and replace suspension components on all tow rig types including single axle, tandem axle, and tri-axle configurations.
- › Leaf spring replacement
- › Air bag suspension repair
- › Shock absorber replacement
- › U-bolt and spring hanger repair
- › Tandem axle suspension rebuild
03Axle & Drivetrain Repair
Axle failures on heavy tow rigs are expensive and dangerous. We service and repair drive axles, steer axles, and tandem axle setups on all tow truck configurations — from light-duty rollbacks to heavy rotators.
- › Drive axle repair & replacement
- › Steer axle service
- › Tandem axle repair
- › Differential repair
- › Axle seal replacement
04Wheel Alignment & Steering
Improper alignment on a heavy tow truck causes accelerated tire wear, handling problems, and puts stress on every steering component. We align tow trucks, wreckers, rollbacks, and semi trucks using precision alignment equipment calibrated for heavy commercial vehicles.
- › Front-end alignment
- › Semi truck wheel alignment
- › Thrust angle alignment
- › Steering gear adjustment
- › Tie rod and drag link service
05Chassis & Body Work
From cracked crossmembers to worn body mounts, chassis-level repairs on heavy tow trucks require the right equipment and the right experience. We handle all chassis work in-house — no outsourcing, no waiting for a third-party shop.
- › Crossmember repair & replacement
- › Body mount replacement
- › Subframe repair
- › Cab mount service
- › Rust repair and reinforcement
06DOT Compliance Repairs
A heavy duty tow truck that fails a DOT inspection is a truck that can't work. We identify compliance issues, perform the required repairs, and document everything you need to get back on the road legally and safely.
- › DOT pre-inspection assessment
- › Brake system inspection & repair
- › Lighting and electrical compliance
- › Steering and suspension compliance
- › Documentation and record-keeping
