Precision Auto Service in Chula Vista has operated from 619 K Street since 1994, staffing ASE-certified technicians who diagnose and repair both foreign and domestic vehicles. Wheel-alignment work on the shop's computerized rack corrects camber, caster, and toe settings to OEM specifications — a calibration step that pairs naturally with tire mounting at American Tire Depot when customers swap seasonal or worn rubber. The service menu covers brake-pad and rotor replacement, engine tune-ups with spark-plug and ignition-coil swaps, cooling-system flushes, and AC recharge using R-134a or R-1234yf refrigerant depending on model year. Scan-tool diagnostics read OBD-II fault codes across engine, transmission, ABS, and airbag modules, isolating misfires, oxygen-sensor faults, and evaporative-system leaks before authorizing parts. Collision-related suspension geometry issues that surface after fender or quarter-panel repair route through the alignment bay following body work at shops such as Pacific Star Auto on Jacqua Street. Technicians verify brake-rotor runout with a dial indicator at a maximum tolerance of 0.002 inches before resurfacing on a Ammco or Pro-Cut on-car lathe to restore pedal feel.
