East County Alignment & Brake in Santee has anchored the Woodside Avenue industrial corridor since 1978, building one of Southern California's largest independent suspension-specialty operations. Four-wheel computerized alignment corrections measure camber, caster, and toe angles to manufacturer spec on everything from sedans to Class A motorhomes, with complementary mechanical repair available next door at Rose Automotive Repair. The RV program addresses Ford F53, E450, and Freightliner P4XL motorhome chassis along with fifth-wheel trailer axle geometry, covering platforms that few independent alignment facilities in East County San Diego can service. Brake work spans hydraulic-line fabrication, rotor resurfacing, drum machining, and ABS module diagnostics for both air-brake commercial vehicles and hydraulic passenger systems. Suspension upgrades include coilover conversions, leaf-spring re-arching, and leveling-kit installations for off-road truck builds, a segment of the East County market also served on the powersports side by Full Throttle Power Sports on Mission Gorge Road. Highest-tier services include thrust-angle and geometric-centerline alignment protocols for Class A motorhomes exceeding 40 feet, using extended-bay rack systems and heavy-duty turnplates rated above 10,000 lb per axle.
