Drivetrain and Suspension Scope
Whether you are rebuilding the Vari-Lok differential or replacing control arms, this manual outlines the exact factory specifications for the WJ platform. Content spans comprehensive wheel alignment data, including caster, camber, and toe specifications for standard and Up-Country suspensions. It also details hub and bearing service alongside steering linkage adjustments. Proper workshop maintenance requires strictly adhering to factory safety protocols, particularly when handling high-tension coil springs or compressed suspension bushings.
Technical Data and Specifications
Skip the guesswork. You get precise fluid capacities, such as 5.7 liters of engine oil for the 4.0L and 4.7L blocks, while the 2.7L diesel requires 6.5 liters. Need transmission fill volumes? The 545RFE automatic takes 5.2 liters for 2WD and 6.2 liters for 4WD models.
This factory workshop documentation provides rigorous torque charts. Front shock absorber lower nuts require exactly 28 N·m (250 in. lbs.), and front axle stabilizer bar retainer bolts are specified at 92 N·m (68 ft. lbs.). You will also find strict assembly tolerances, like the required 0.13–0.20 mm (0.005–0.008 in.) rear axle ring gear backlash.
