Trailer Work, In the Yard or on the Shoulder

A trailer that will not roll costs more than it looks like it does, because it strands the tractor with it. Trailer work is field work more often than people expect, and it is a large part of what Rig Doctor does.

Suspension and running gear cover air bags, height control valves, shocks, hangers, u bolts, spring packs and the slider itself. Hub work covers seals, bearings, drums and the wheel end that has been running hot and telling nobody. A hub torn down on the ground under a trailer is a normal afternoon here, not an exception.

Lighting and air are the two items that turn a rolling trailer into a written violation. A chafed line against the frame, a corroded seven way, a marker that only lights in the dry. All of it gets repaired properly rather than taped over and handed back.

The mechanical odds and ends matter too. Landing gear that will not crank, a door that will not latch, a hung mud flap, a bracket sheared off after a tire came apart. Small parts, big delays, and every one of them is a field repair.
