Jeep Suspension Repair & Service
Coil Spring, Control Arm, Track Bar & Complete Suspension Service for Wrangler, Gladiator & Cherokee Platforms
MST Motorsports provides professional Jeep suspension repair, lift installation and geometry correction in Washington, Utah, serving St George and Southern Utah. Our factory-trained, certified technicians bring more than 80 years of combined experience to solid-axle Wrangler and Gladiator suspension, and qualifying automotive repairs are backed by our 36-month/36,000-mile nationwide warranty on parts and labor.
The trails at Sand Hollow, Hurricane Cliffs and the surrounding desert load Jeep suspension components hard, and worn control arm bushings, track bar play and death wobble are the results we see most. We diagnose and repair those, and the axle, transfer case and steering intervals Jeep publishes for the Wrangler are set out in our Jeep Wrangler maintenance schedule.
We install and service Jeep suspension and armor components from EVO Manufacturing and GenRight Offroad alongside the Teraflex, Synergy, Metalcloak and Rock Krawler parts already common on lifted Wranglers and Gladiators in Washington County.
Coil Springs & Lift Kit Service
Coil springs set a Jeep's ride height, articulation and load capacity, and factory springs sag over time on Jeeps carrying bumpers, winches and armor. Sagging springs reduce ground clearance and articulation on Sand Hollow ledges and rock.
We install coil springs and complete lift kit systems from Teraflex, Rough Country and other manufacturers. Control arm geometry, track bar alignment, brake line clearance, bump stop adjustment and post-installation alignment are all handled as part of the job, so the lifted Jeep handles predictably on-road and off.
Control Arms & Track Bar Service
Control arms locate the axles on a Jeep solid axle suspension and the track bar centers them under the vehicle, so their condition determines handling, alignment retention and death wobble behavior. Trail use at Sand Hollow accelerates bushing wear on both.
We install adjustable control arms so caster and pinion angle can be corrected on a lifted Jeep, where factory arms leave angles that affect steering, drivability and driveline vibration. We also inspect, repair and replace track bars, including heavy-duty replacements for lifted applications, because a worn track bar bushing or a bent track bar is one of the most common triggers for death wobble.
Death Wobble Diagnosis & Repair
Death wobble is an oscillation of the front axle at highway speed, triggered by a bump, and it comes from play or wear across the front-end system rather than from one component. A steering stabilizer damps the motion, so the worn component itself is what gets repaired.
Our technicians inspect every front-end component — track bar and bushings, tie rod ends, drag link, ball joints, wheel bearings, unit bearings, control arm bushings and steering box — and replace what is worn. We then verify alignment and steering geometry so the repair holds.
Sway Bars & Stabilization Systems
Sway bars control body roll during cornering and lane changes, and on trail-capable Jeeps the disconnect system lets the axles articulate freely off-road and reconnects for on-road stability. Manual quick-disconnect links and electronic disconnect systems both need periodic service.
We service sway bar links, bushings, electronic disconnect motors and the sway bars themselves, and install extended links on lifted Jeeps to suit the added suspension travel. Correct sway bar function matters most on a lifted Jeep with a higher center of gravity.
Solid Axle Alignment & Caster Correction
Solid axle alignment on a Jeep Wrangler (JK, JL) and Gladiator (JT) adjusts toe at the tie rod and caster through control arm length, because camber is set by the axle housing itself. That is what separates it from independent suspension alignment.
Lifting a Jeep changes the angle of every control arm and reduces caster, which shows up as poor steering return and instability at highway speed. We align lifted Jeeps with adjustable control arms from Teraflex, Synergy, Metalcloak and Rock Krawler by setting caster for the lift height and then toe. Cherokee (XJ) uses the same solid-axle approach, while Cherokee (KL) and Grand Cherokee (WK2, WL) use independent front suspension and follow lifted-truck alignment principles, and every Jeep alignment runs on our Hunter Hawkeye Elite.
Post-Trail Alignment Check
An alignment check after hard trail use keeps tire wear and steering feel from drifting, because rock crawling loads steering and suspension components far harder than highway miles do. For Jeeps that run Sand Hollow and other Southern Utah trails regularly, we recommend a check every 5,000 to 10,000 miles or after any significant impact.
A post-trail alignment starts with a front-end inspection of tie rod ends, drag link, track bar, ball joints and wheel bearings. Components that measure within specification are aligned; a bent or worn part is repaired first so the alignment holds.
The rear axle is part of the same check, because its position sets thrust angle — the direction the rear axle pushes relative to the vehicle centerline. A rear axle out of position wears the rear tires unevenly and affects stability, so it is measured and adjusted alongside the front.
Frequently Asked Questions
What causes Jeep death wobble?
Death wobble usually traces to worn or loose front-end components — most often the track bar and its bushings, tie rod ends, ball joints or wheel bearings. Lifted Jeeps are more susceptible because the modified geometry loads those components harder. Our technicians inspect every front-end component to identify and correct the cause.
How often should Jeep suspension be inspected?
For Jeeps used off-road in Southern Utah, we recommend suspension inspection every 15,000–25,000 miles. Jeeps that regularly run trails at Sand Hollow or in the red rock areas should be inspected more frequently. Key items include control arm bushings, track bar condition, ball joints, and coil spring condition.
Can you install a lift kit on my Jeep?
Yes. We install lift kits from Teraflex, Rough Country and other manufacturers. The installation includes correct control arm geometry, track bar adjustment or replacement, brake line extension verification, driveshaft angle check and post-installation alignment.
Do you service Jeep sway bar disconnects?
Yes. Electronic and manual sway bar disconnect systems are common on Wranglers and Gladiators. We service, repair, and install sway bar disconnect systems and verify proper operation both connected and disconnected. Proper sway bar function is critical for on-road stability.
How is Jeep alignment different from regular alignment?
Jeep Wranglers and Gladiators use solid front and rear axles — unlike most modern vehicles with independent suspension. Solid axle alignment adjusts toe and caster through the control arms and track bar, not through camber bolts or adjustable strut mounts. This requires different knowledge and approach than standard passenger car alignment.
Can you align a lifted Jeep with adjustable control arms?
Yes. We commonly align Jeeps with aftermarket adjustable control arms from Teraflex, Synergy, Metalcloak, Rock Krawler, and others. These adjustable arms allow us to correct caster after lifting — something that isn't possible with factory fixed-length arms on significant lifts.
My Jeep pulls to one side after wheeling. Do I need an alignment?
Possibly, but pulling after off-road use can also indicate a bent tie rod, shifted track bar, worn ball joint, or damaged steering component. We inspect the front end before aligning so any adjustment corrects the real issue rather than covering a damaged component. If components are damaged, we repair those first.
What Jeep models do you service?
We service all Jeep models including Wrangler (JK, JL), Gladiator (JT), Cherokee (XJ, KL), Grand Cherokee (WJ, WK, WK2, WL), and classic CJ platforms. Our technicians understand the unique suspension architecture of each platform.
