Heavy-duty tires are too expensive to use as an alignment gauge. If your steers are feathered, your drives are scrubbing, or the truck is dog-tracking down the 401, the geometry is wrong — and you are paying for it in rubber, fuel, and driver fatigue. KG Truck Services performs precision wheel alignment in Mississauga on tractors and trailers: steer axles, drive axles, and trailer axles, including multi-axle setups that a passenger-car rack cannot even see.
What we measure and why it matters
Alignment on a truck is not “set the toe and send it.” We measure toe, camber, and caster on the steer axle, then we look at thrust angle and axle parallelism on the drives. A tractor can have a perfect steer alignment and still eat tires if a drive axle is not square to the frame. Trailers need the same honesty: tandem and spread axles that are not parallel will scrub every kilometre. We use dedicated heavy-duty alignment equipment, not a passenger-car machine with the arms extended and a hope.
Symptoms we hear every week: the truck pulls left under braking, the steering wheel is off-centre on a straight highway, the driver is fighting a wander, or one steer is worn on the inside while the other looks new. Those are alignment and suspension problems until proven otherwise. Worn kingpins, loose tie-rod ends, collapsed spring pins, and a bent radius rod will not hold an alignment. We inspect those components first. Setting toe on worn parts is a temporary correction that lasts until the next pothole.
Alignment after repairs, not just when tires die
Get an alignment after spring or kingpin work, after a curb or collision, after differential or axle housing work, and whenever you mount a new set of steers. New tires on a crooked axle are a short-term cosmetic fix. Fleets that align on a schedule — not only when a driver complains — spend less on rubber and get more miles per gallon because the truck is not dragging itself sideways. That is not marketing math. Scrub is load. Load is fuel.
We align Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, Western Star, and the trailers they pull. Lift-axle configurations, pusher axles, and tag axles are part of the conversation; they have to be set in the position you actually run. Tell us how the truck lives — highway, city, dump, or mixed — so we set caster and toe for that use instead of a generic spec that fights the driver.
Same shop as brakes, diffs, and inspections
If we find a tire that is already to the cords, a leaking hub, or a brake that is dragging, we can repair it here. Alignment is often booked with a DriveON safety inspection or a DOT-style check so the truck leaves legal and tracking. If the truck cannot come in, some measurements and worn-component checks can start as a mobile visit, but a full alignment belongs on the rack.
Book a heavy-duty alignment at 6771 Columbus Road, Mississauga. Bring the tractor, and bring the trailer if that is where the wear is. Call (905) 564-0880 with the make, axle configuration, and what the tires are doing. We would rather correct the geometry once than sell you another set of steers in four months.
