Freightliner & Western Star Repair Jerome, Idaho

Cascadias, Western Stars, and the Detroit engines in them

The Cascadia is the most common fleet truck on I-84, and we see plenty of them. We service Detroit Diesel DD13 and DD15 engines along with the rest of the truck: diagnostics for check engine lights, aftertreatment and regen problems, derates, cooling systems, fuel systems, and electrical faults.

Western Star owners get the same coverage — vocational or highway, we work on the chassis, brakes, air system, suspension, and driveline just like the engine. Fleet or owner-operator, one truck or twenty, the process is the same: diagnose, quote, fix. The price we quote is the price you pay.

What tends to go wrong

Across the industry, emissions-era Detroit-powered trucks share the usual modern headaches: DPF plugging from idle-heavy duty cycles, aftertreatment sensor faults, and derates that show up mid-load. Add Magic Valley winters — black ice, drifting snow, gelled fuel in cold snaps — and batteries, air dryers, and brake systems earn their keep.

We state problems the way we find them. No scare lists, no invented failures — just what the codes, the pressures, and the wear actually show.

Fleet-friendly shop, roadside backup

Fleets like our hours: 7 AM to 10 PM, every day, so trucks get fixed around dispatch schedules instead of against them. Our Jerome bays sit minutes off I-84 exit 168, and our mobile trucks cover every exit from Bliss to Declo with a flat call-out fee stated before we roll.

A local answers the phone. If you run multiple Cascadias through the corridor, save our number — one call handles a breakdown at exit 173 the same as a scheduled brake job.

DOT annuals for tractors and trailers

Every tractor and every trailer needs its own annual inspection. We do both in one visit, performed by qualified inspectors per FMCSA 49 CFR 396.19, and keep the reports for 14 months — handy for fleets tracking paperwork across several units.
