Steps
Raise the vehicle and remove the wheel
Loosen the wheel and axle nuts on the ground, then raise and support the truck securely. Remove the wheel and keep the hub hardware organized.
Remove the brake rotor and secure the caliper
Remove the caliper and bracket, supporting them without straining the brake hose. Remove the rotor and keep the ABS wiring clear of the suspension work.
Move the axle and control arm
Support the knuckle and disconnect the axle and required control arm joints using approved separators. Place a drain pan under the differential if the axle must be withdrawn, and protect the CV joints and seals from dirt or impact.
Remove the old strut assembly
Disconnect the sway bar link and strut fasteners, then support the knuckle so it cannot fall. Remove the strut mount nuts and lower the assembly out of the wheel well without stretching brake or ABS wiring.
Install the replacement strut assembly
Use a complete preassembled strut if you do not have professional spring-compression equipment. Guide the assembly into place, start the upper mount nuts, and secure the lower mount and sway bar link to specification.
Reinstall the axle and control arm
Reconnect the control arm and axle, making sure the axle is fully seated and its seal is undamaged. Restore brake and ABS harness brackets, then tighten suspension and axle fasteners to the vehicle specifications.
Reinstall the rotor and caliper
Fit the rotor, caliper bracket, pads, and caliper, tightening all fasteners to specification. Route the brake hose and ABS wire through their retainers with enough clearance for steering and suspension travel.
Install the wheel and verify
Reinstall the wheel and torque its nuts and axle fastener to specification. Pump the brake pedal until firm, check for fluid leaks, and have alignment checked before a cautious road test.
Check your vehicle’s repair manual for exact specifications and fit.
