Axle Boy has fully trained and equipped four wheel drive specialist that use the latest techniques and equipment to accurately and effectively diagnose siuations like this failed control module in a Ford Explorer. This vehicle also received an overhaul to the rear 8.8 IRS axle and limited slip assembly.

The Eaton Posi LSD is the perfect way to control traction in street rods, light duty pickups and all types of tarmac running race cars. The Eaton Posi LSD prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel.
