Measure the fleet once, then measure the outliers
Most fleets align reactively, one truck at a time, after something has already been paid for. A better pattern exists and it costs less than people assume.
Measure every unit once over a period that suits you, and write the figures down. That is the sweep. What it produces is not a list of repairs; it is a baseline, and the baseline is what makes every later measurement meaningful.
After that, the fleet divides itself. Units that were within specification get measured again on an interval or when something happens to them. Units that were out get corrected and then watched, because a truck that goes out of alignment twice is telling you about a worn component rather than about alignment.
The sweep is also the only reliable way to find the units nobody was going to report. A truck can be well out and still drive acceptably, and drivers adapt to a pull within days.
What gets measured
Steer axle angles, drive axle alignment, and the relationship between them. The last of those produces a truck running slightly crabbed down the road, which costs fuel as well as rubber and generates no complaint from anyone.
Where the measurement points at a worn or bent component rather than an adjustment, you get told. Aligning around a worn part produces work that undoes itself, which is how a fleet ends up believing alignment does not hold.
The trailer is the other variable
A trailer that tracks crooked drags whatever is pulling it, and in a fleet that swaps trailers it spreads that wear across several tractors. Trailer alignment is offered here, and a sweep that covers tractors but not trailers leaves the most confusing cause in place.
What a correction protects
Steer tire life, fuel, and the casing. A steer scrubbed on one shoulder will not pass at the retread plant on this site, so an alignment problem costs the tire and its retread value together.
About this store
The Denver store runs seventeen services, carries all nine Purcell tire categories, and is managed by Jake Perry. Colorado Springs and Loveland also align heavy trucks; Craig does not.
