Differential Leak and Axle Seal Repair
Differential Repair — Cheyenne, WY
Differential leaks come from a few usual suspects: the pinion seal up front, axle shaft seals at the wheel ends, and the cover gasket. An axle seal leak is the sneaky-dangerous one — gear oil runs onto the rear brakes, and oil-soaked shoes or pads stop dramatically worse than dry ones. Wet streaks on the inside of a rear wheel deserve prompt attention.
TDC replaces seals properly, which includes finding out why they failed: a worn bearing letting the axle shaft wobble will destroy new seals as fast as you install them. The vent gets checked too — a plugged axle vent builds pressure that pushes oil past healthy seals.
