What Is Tow Truck Hydraulic System Repair And Why Does It Matter?
The hydraulic system is the powerhouse behind everything a tow truck does — raising and lowering the bed, operating the boom, driving the winch, and controlling every piece of moving equipment on the rig. When the hydraulic system fails, the truck stops working. Not slows down. Stops. A hydraulic failure on a job means a stranded truck, a stranded customer, and lost revenue for every hour it takes to get the rig back in service.
Tow truck hydraulic systems are more complex than the hydraulic systems on most other commercial vehicles. They run at higher pressures, through more components, and under more demanding duty cycles. The pump, the cylinders, the PTO, the control valves, and the winch all work together as a system — and a failure in any one component affects everything downstream. At Quik Tow Repair, hydraulic system repair is one of our core specialties. We work exclusively on tow trucks and understand how these systems are configured on every major tow rig type — and we test every repair against the operating pressures outlined in Parker Hannifin hydraulic system guidelines.
We repair and rebuild entire hydraulic systems in-house at our Pomona shop — from a single leaking line to a full system rebuild. Every repair starts with a proper system diagnosis so we identify the actual root cause, not just the visible symptom. You get a written estimate before we start and a road-tested truck when we're done.

Hydraulic System Repair Services We Offer
Every hydraulic repair is performed in-house at our Pomona shop. We cover the full system — not just the visible failure point.
01Full Hydraulic System Diagnosis
Most hydraulic failures have an underlying cause that isn't the obvious symptom. A leaking cylinder might be caused by excessive system pressure. A slow bed might be a worn pump or a restricted valve. We diagnose the full system before recommending any repair — so you fix the actual problem, not just the part that shows it.
- › Full system pressure test
- › Flow and leakage diagnosis
- › Component-by-component assessment
- › Written diagnosis report
- › Root cause identification before estimate
02Hydraulic Pump Repair & Rebuild
The hydraulic pump is the heart of the system. A worn or failing pump causes slow operation across every hydraulic function — slow bed, weak boom, sluggish winch. We inspect, repair, and rebuild hydraulic pumps on all tow truck configurations, replacing worn components and verifying output pressure after rebuild.
- › Pump pressure and flow testing
- › Internal wear inspection
- › Pump rebuild and component replacement
- › Seal and gasket replacement
- › Post-rebuild pressure verification
03Hydraulic Line & Fitting Repair
Leaking hydraulic lines and fittings are the most common hydraulic issue on working tow trucks. High-pressure hydraulic fluid leaks are a fire hazard, an environmental issue, and a safety problem. We replace hydraulic lines, fittings, and hoses with components rated for the operating pressure of your specific system.
- › High-pressure line replacement
- › Fitting and coupling replacement
- › Hose fabrication to spec
- › Full system pressure test after repair
- › Leak-free verification before release
04Hydraulic Fluid Service
Contaminated or degraded hydraulic fluid is one of the most common causes of premature pump and cylinder failure on tow trucks. We flush, filter, and refill hydraulic systems with the correct fluid type and viscosity for your truck and operating environment.
- › Fluid condition assessment
- › Full system flush
- › Filter replacement
- › Correct fluid spec refill
- › Contamination source identification
05Hydraulic Reservoir & Cooler Service
A cracked or corroded reservoir contaminates the entire system. A blocked cooler causes fluid overheating, which degrades seals and accelerates wear across every hydraulic component. We inspect, clean, repair, and replace reservoirs and coolers as part of complete hydraulic system service.
- › Reservoir inspection and cleaning
- › Crack and corrosion repair
- › Cooler flush and blockage clearing
- › Cooler replacement if needed
- › Temperature verification after service
06Full Hydraulic System Rebuild
High-mileage tow trucks that have run hard for years often need a complete hydraulic system rebuild. A full rebuild restores full system pressure, response time, and operating capacity.
- › Complete system inspection and documentation
- › Pump, cylinders, valves, and lines rebuilt
- › All seals and wear items replaced
- › Full pressure and flow testing
- › Fleet rebuild scheduling available
Why SoCal Towing Companies Choose Quik Tow Repair For Hydraulic Work
Full System Approach
We diagnose the full hydraulic system before recommending repairs. We don't replace the obvious part and send you on your way — we find the root cause so the same problem doesn't come back in 30 days.
Tow Truck Specialists
We work exclusively on tow trucks. Tow truck hydraulic systems run at different pressures and duty cycles than most commercial equipment. Our technicians know the specific configurations of flatbeds, wreckers, rollbacks, and integrated units.
In-House Repair
All hydraulic repairs happen in our Pomona shop — pump rebuilds, line fabrication, cylinder work, valve service. No outsourcing, no waiting for a third-party hydraulic shop.
Fast Turnaround
A hydraulic failure stops your truck completely. We prioritize hydraulic repairs and give you a clear timeline at the estimate. Most hydraulic repairs are completed in 1–3 business days.
Written Documentation
Every hydraulic repair comes with a written diagnosis report and service documentation. Useful for fleet records, insurance purposes, and verifying the repair was performed correctly.
Fleet Accounts
Fleet operators with 2+ trucks get priority scheduling on hydraulic repairs, proactive hydraulic inspection programs, and volume pricing across all hydraulic services.
How Hydraulic System Repair Works At Our Shop
From your first call to a fully operational hydraulic system — here is exactly what to expect.
Call 888-628-4008 or submit our form. Tell us what the hydraulic system is doing — slow operation, no movement, a leak, or a complete failure. We confirm availability and call you back same day.
We connect your truck to our hydraulic diagnostic equipment and test the full system — pressure, flow, and component condition. You receive a written diagnosis before any repair begins, covering what's wrong, what caused it, and what we recommend.
No work starts without your written approval of the estimate. We repair the full system — not just the visible failure — and update you at key milestones. No additional work without your go-ahead.
After repair we run the full hydraulic system through all functions under load conditions. Every cylinder, the boom, the winch, the bed — all tested before we call you. You leave with a truck that works, documented and verified.

What SoCal Towing Companies Say About Our Hydraulic Work
"My rollback bed stopped lifting mid-shift. Called Quik Tow at 7am, had the truck assessed by 9, quote by 10:30, repaired by end of day. Turned out to be a valve issue causing backpressure on the cylinder. They found the actual cause, not just the symptom. Back on the road same day."
"We run 7 trucks and set up a hydraulic inspection program with Quik Tow. They check the full system on each truck every 6 months. Caught a pump that was about to fail on our main wrecker before it took the truck out of service. Preventive maintenance through them has saved us thousands."
"Had a hydraulic leak on my integrated unit that two shops said needed a full system replacement. Quik Tow diagnosed it as a failed high-pressure line and a worn pump seal. Fixed both, flushed the system, pressure tested everything. Half the cost of what the other shops quoted."
