Keeping Semi-Trailers Rolling in Oregon—Parts and Service Checklist

Between the steep grades of I-5 near Grants Pass, the wet winters, and the constant wear from long hauls, having the right parts on hand isn’t optional—it’s essential. At Great Western Trailer’s Grants Pass, OR location, we make it our mission to keep trailers road-ready with the parts and support that drivers and fleets need. 

Here’s a practical checklist of parts every Oregon hauler should keep an eye on:

1. Brakes, Tires, and Hubs – Your braking system is your first line of defense on Oregon’s mountain passes. Regularly inspect drums, shoes, and hubs for wear, and don’t ignore the signs of uneven tire wear—it often points to an underlying issue in alignment or hubs. At our Grants Pass branch, we carry replacement brakes, hubs, and trailer tires built for long hauls and mixed terrain. 
2. Toolboxes – Toolboxes protect your straps, chains, and personal gear from Oregon’s rain and road grime. They’re also a simple upgrade that saves headaches on the road. 
3. Cargo Control – Troopers watch for load securement compliance, and fines can be steep if cargo isn’t properly tied down. Having the right cargo control parts ensures you’re not only safe, but also compliant.
4. Dunnage Racks  – Keeping lumber dunnage or blocks off the trailer deck makes life easier, prevents lost materials, and speeds up load changes. If you’re frequently moving flatbed loads through Grants Pass, a reliable dunnage rack saves time and space.
5. Loading Ramps – Heavy equipment and uneven loading areas are common in Oregon’s logging and construction sectors. Sturdy ramps are essential for safe, efficient loading—especially for owner-operators who handle freight without dock access. 
6. Lift Gates – For fleets delivering to tight city stops in Medford, Eugene, or Portland, lift gates are the unsung heroes of efficiency. Regular maintenance of hydraulics and power units keeps deliveries moving without downtime. 
7. Curtain Vans & Roll Tarps – Curtain vans and roll tarp systems shield cargo from rain, snow, and road spray—keeping loads intact and customers happy. 
8. Suspension and Axles – Rough highways and heavy loads put a lot of strain on trailer suspension systems. Staying ahead on bushings, springs, and axle components helps avoid roadside breakdowns, especially on the long stretches between Grants Pass and Portland. 
9. Trailer Body Parts – Doors, panels, and flooring take constant abuse. Replacing worn body parts not only extends the life of your trailer but also helps keep CSA scores in check.
10. Electrical & Lights – Clear visibility is a must on Oregon highways. DOT-approved lights, wiring harnesses, and connectors ensure your trailer is compliant and visible in rain, fog, and snow.
