9 Tips for Better Trailer Maintenance
When talk turns to maintenance, it’s usually the tractor that gets all the attention. While today’s trailers are designed to last longer, they still need some TLC.

The following trailer maintenance tips can help ensure your trailers are always in top operating condition.

1. Check the air

Tires are a major expense, so they deserve your attention. “Proper tire air pressure is key to tire longevity,” says Mike Goor, president of Contract Leasing Corp., a trailer leasing, sales and service company. Since drivers are often too busy to check tires as they should, he recommends tire pressure monitoring or inflation systems.

Chris Steph, Stemco Intelligent Transportation Systems business leader, suggests these three simple checks:

• Verify that the system pressure is set correctly

• Check the auxiliary battery switch (ABS)/auxiliary power fuse

• Check the system shut-off valve position.

More specifically, check regulator pressure at least once a quarter and check the power fuse monthly, since the driver warning lamp will not illuminate without power. The system shut-off valve needs to be checked every time there is a visual inspection of the trailer.

If your tires are properly inflated but you’re still seeing tire wear, the problem is probably not with the tires, says Russ Franks, field service manager for Meritor. “Unusual tire wear is an indication you have something wrong with the undercarriage, suspension, shock absorbers or axle alignment.”

2. Inspect suspensions

Visually inspect suspensions looking for signs of irregular wear, tears or heat cracks on the air springs, advises Dave Vanette, new business development manager at Firestone Industrial […]
