Frame & Body Work

We can service all your bodywork needs for trailers, like replacing fenders, jacks, side panels, decking, ramp gates, tires/wheels, tarps, and much more. For whatever issue you're having, we will be sure to do our best to get you taken care of the right way!

Preventative Maintenance

1. Wheels and Tires:
   1. Tires can be an easy-to-spot wear item to keep in mind during routine maintenance. Check tread depth and balding, wear, broken belts, and look for signs of dry rotting to make sure that your tires are up to date and safe for the road.
2. Bearing Repacks are an effective time to fully inspect and change out small items that could have a big impact on towing safety. Since the hubs fully removed, this allows for easier access to inspect brakes, drums, spindles, and even some suspension components such as leaf springs and shackles straps.
   1. A key indicator that a trailer should have the bearings inspected, repacked, or replaced is if the trailer tire rocks back and forth when pushed on. Any wiggle room in the hub allows for more wear and tear on the bearings and races, potentially allowing grooves to form on the axle spindle if not addressed correctly.
3. Grease Points:
   1. Most trailers will have multiple grease points for moving components. Lighter utility, car hauler, or enclosed trailers will typically have just a few grease points for ramp doors, toolbox hinges, jacks, and other gate/door openings.
   2. Heavier dump trailers, powertail deckovers, or tilting equipment trailers will have larger cylinders that will require a more thorough inspection and greasing process to ensure that the main moving components are operating as they should be.
4. Our two store locations offer a full DOT inspection for any commercial vehicle or trailer. We can quote out any small or large repair that may be recommended or required to keep everything up-to-date and roadworthy.
