Why a tractor goes out of alignment
Alignment on a heavy unit is not one adjustment. It is the relationship between the steer axle, the drive axles and the frame, and it moves: a curb strike, a deep pothole, worn bushings, a trailer pulling against the tractor, or simply high mileage on rough road.
The truck rarely announces it. What shows up instead is tire wear, and by the time a driver notices the truck pulling, a set of steer tires has usually paid for the alignment several times over.
What the Idaho Falls store looks at
This is a commercial location, so heavy units are the work rather than a sideline. An alignment here covers the steer axle angles, drive axle thrust, and how the whole unit tracks down the road. Where the wear pattern points at something else, the store will say so: alignment does not fix a bent component or a worn bushing, and fitting a new set of tires over an unresolved problem is how fleets buy the same tires twice.
Store manager Bill Goode's team also handles trailer alignment in Idaho Falls, which matters because a trailer that tracks crooked drags the tractor's tires sideways for every mile it is pulled. Aligning the tractor and leaving the trailer is half a job.
When to book one
- A new set of steer tires is going on. Align before fitting, not after.
- Steer tires are wearing on one shoulder, or feathering across the tread.
- The truck pulls, or the steering wheel sits off center on a straight road.
- The unit has hit something hard, or has been in service long enough that nobody remembers the last alignment.
- Tires are being pulled early across the fleet and nobody can say why.
What else this store does
Idaho Falls Commercial runs seven services: 24-hour roadside assistance, fleet services, heavy-duty truck alignment, trailer alignment, retreading, tire and wheel balancing and wheel refurbishing. All nine Purcell tire categories are carried, so a unit can be aligned and shod in the same visit.
Car and light truck repair is not done here. That work goes to the Purcell consumer store at 595 East Anderson, elsewhere in Idaho Falls.
