Suspension, Steering & Driveline Repair at Your Yard
Air bags, springs, u-joints, carrier bearings, wheel seals — the wear items that fail slowly, then all at once.
Suspension and driveline problems announce themselves: a lean at the fifth wheel, a clunk on take-off, a vibration at highway speed, a wheel seal weeping onto a brake drum. Catch them at your yard and they're maintenance; ignore them and they're a roadside call with cargo on the clock. Ronin Mechanical repairs both — at $130/hour, anywhere south of Duncan.
We service air-ride and spring suspensions on tractors and trailers, steering components, and the driveline from clutch to differential yoke: u-joints, carrier bearings, slip yokes, and the seals and bearings that keep wheels turning. Work happens where the truck is parked, with proper support equipment and torque specs — mobile doesn't mean approximate.
What we handle on-site
- Air suspension — bags, height control valves, leveling faults
- Spring, hanger and bushing replacement
- Shock absorber inspection and replacement
- Kingpins, tie rods and steering component wear
- U-joints, carrier bearings and driveline vibration diagnosis
- Wheel seals, hub service and bearing adjustment
- Fifth wheel inspection, adjustment and repairs
- Clutch adjustments and hydraulic clutch faults
Wear items on a schedule, not a surprise
Almost everything on this page is predictable wear. U-joints don't fail young, air bags crack visibly before they let go, and a kingpin telegraphs long before a steer tire scallops. That's why suspension and driveline checks are built into our preventive maintenance visits — the cheapest version of this work is the one you scheduled.

Suspension, Steering & Driveline — FAQs
My tractor is leaning to one side on air ride. Can I drive it?
A lean usually means a failed bag, a stuck or failed height control valve, or a leak on one circuit. Driving far on a collapsed bag risks driveline angles, tire wear and worse. If it's leaning in the yard, book a same-day-if-possible visit by text; if it dropped suddenly on the road, pull over somewhere safe and text 250-974-7899.
What does a driveline vibration at speed usually mean?
Most often a worn u-joint or carrier bearing, occasionally a slipped or out-of-phase driveline after other work. It's worth diagnosing quickly: a u-joint that lets go at highway speed does expensive collateral damage. We can usually confirm the source in one yard visit.
Do you do wheel seals and hub work on site?
Yes — leaking wheel seals are bread-and-butter yard work, along with bearing service and proper end-play adjustment. An oil-soaked brake shoe is an out-of-service defect waiting for a scale, so a weeping hub is worth a text sooner rather than later.
Can you adjust or repair a clutch at my yard?
Clutch adjustments, linkage and hydraulic issues are normal mobile work. Full clutch replacement is a big job that's possible at a well-equipped yard — we'll assess and quote the time honestly by text before committing either way.
