AXLE SEALS REPLACED

The most common job in our bays.

A leaking axle seal is the first sign your differential fluid is contaminating your brake pads. We replace it before you lose both.

Dana 30, Dana 35, Dana 44 — we stock every seal on the shelf. Same-day turnaround, no appointment required for seal-only jobs.

FRONT-END DIAGNOSIS
98.6%
FIRST-FIX RATE · DEATH WOBBLE

We diagnose by feel before we plug in a scanner.

Death wobble is never one part. It's a system failure — track bar, ball joints, tie rods, caster angle, tire balance. We inspect all of it under load.

Physical inspection under load before any scan tool. We find the root cause, not the symptom. 98.6% of death wobble jobs leave fixed on the first visit.

AVERAGE TURNAROUND · LIFT KIT INSTALL

In at 8am. Trail-ready by noon.

A proper lift is alignment, caster correction, brake line relocation, and a test drive — not just bolting on springs. We do it right the first time.

Full lift kit install including alignment on our in-house Hunter alignment rack. Caster correction, brake lines, extended sway bar links — complete job, not a partial.
