Truck & Trailer Alignment So Your Whole Rig Tracks Straight

Trailers don't steer, but their axles still need to be aligned. If a trailer's axles aren't square to the kingpin, the trailer pulls to one side, drags its tires sideways, and forces the tractor to compensate with constant steering corrections. Wetcreek Repair Solutions aligns trailer axles and checks how the full combination tracks for carriers and owner-operators throughout Joplin, MO.

Trailer and Combination Alignment Services

Trailer alignment starts at the kingpin, since that's the point the trailer pivots around. We measure each trailer axle against the kingpin to make sure it's square, then check that tandem axles are parallel to each other. Adjustments are made using the trailer's adjustable arms or hangers, and worn suspension parts are addressed so the settings hold. We also confirm that the trailer tracks in line behind the tractor once both units are aligned.

Trailer Repair and Alignment That Saves Tires on Both Units

A misaligned trailer wears out its own tires and also causes the tractor's steer and drive tires to wear unevenly as the driver fights to keep the rig straight. Our truck repair shop aligns tractors and trailers so both units work together rather than against each other. When worn bushings, damaged hangers, or slider problems are found, our trailer repair team fixes them before the alignment is set. Fleets include trailer alignment in their regular truck service in Joplin, MO to cut tire costs across the entire combination.

Frequently Asked Questions

  • Why do trailers need to be aligned if they don't steer?
    Trailer axles must be square to the kingpin and parallel to each other so the trailer follows the tractor straight. Misaligned axles cause the trailer to drag tires sideways, wearing them quickly and increasing fuel use.

  • What are signs my trailer is out of alignment?
    Look for a trailer that sits offset to one side when viewed in the mirrors on a straight road, uneven wear on trailer tires, or a tractor that pulls when hauling that trailer but not others.

  • Can trailer axles be adjusted?
    Many trailer suspensions have adjustable radius arms or eccentric bushings that allow axle alignment. On fixed designs, alignment corrections may require replacing or repositioning worn or damaged components.

  • Does a sliding tandem affect trailer alignment?
    Yes. Worn slider pins, damaged rails, or a slider that doesn't lock fully can let the axle assembly shift, throwing alignment off. These parts should be inspected as part of a trailer alignment.

  • How often should a trailer be aligned?
    Trailers should be aligned when installing new tires, after suspension or axle repairs, after hitting a curb or dock hard, or whenever irregular tire wear appears.
