Diagnosis first
We scan, test, and listen before we quote. A misdiagnosis costs you more than the repair. We take the time to find the actual fault, not the most likely one.
Wrench Socket Fixture is a small independent shop. We take on diagnostics, mechanical repair, and pre-purchase inspections. No upsells, no service packages, no waiting-room TV.

We do a lot of these. The $145 flat fee covers 90 minutes of actual inspection time, a written report, and a...

Dale Merritt opened Wrench Socket Fixture in 2014 after eleven years working the line at a dealership group in the midwest. The dealership years were useful. He learned to read wiring diagrams fast, to work on several platforms, and to spot the difference between a real fault and a warranty claim someone was fishing for. What he didn't love was the flat-rate pressure, the upsell quotas, and the way a car could pass through four sets of hands without any one person knowing the whole story. He left in the spring of 2014 and opened this shop with a used lift, a Snap-on scan tool he'd been paying off for two years, and a small client list from people who'd followed him out.
The first two years were tight. He took on anything that came through the door, including a stretch in late 2015 where he was doing a lot of fleet work for a local delivery company, which paid steadily but wasn't the kind of diagnostic work he wanted to build around. By 2017 the shop had found its footing. Word spread through a few local car forums and a neighborhood Facebook group, and the work shifted toward the kind of jobs he actually wanted: intermittent faults, pre-purchase inspections, second opinions on dealer estimates. He added a Pico oscilloscope in 2018 and started doing more electrical diagnosis, which is now a significant part of the workload.
Reading it for the engineering logic, not the nostalgia. Surprisingly useful on first principles.
We're a small shop. Call ahead before dropping by. Walk-ins are welcome but scheduled drop-offs get priority.

Dale handles the estimate, the repair, and the handover conversation. You talk to the person who touched your car, not a service writer reading notes.
We tell you the brand, the part number, and where it came from. OEM where it matters, quality aftermarket where it doesn't. You can look it up.
Nothing gets done without a written estimate you've approved. If we find something extra mid-job, we stop and call. No surprise invoices.
Labor is quoted by the job, not by the hour with a running clock. You know the number before we start.
Dale Merritt spent eleven years as a line technician at a dealership group before opening Wrench Socket Fixture in 2014. He trained through a community college automotive program and holds ASE certifications in engine performance and electrical systems. The dealership work gave him range across platforms and a fast hand with wiring diagrams, but the upsell culture wore him down. He left with a used lift and a scan tool he'd been paying off for two years. Outside the shop he reads a lot of automotive engineering history and takes long drives on two-lane roads when the weather allows. He is currently working through a backlog of ALLDATA service bulletins for late-model European platforms.
