Steps
Support the vehicle and axle
If lifting the vehicle, support the frame securely on jack stands. Place a floor jack beneath the axle to support it before disconnecting the shock.
Remove the old shock
Remove the lower shock nut and bolt, then remove the upper mounting bolt. Withdraw the bolts and lower the shock out of its mounts.
Install the replacement shock
Position the new shock and start the upper bolt by hand. Align the lower mount, install its bolt and nut, and snug both connections without forcing the bushings out of alignment.
Settle the suspension and tighten
Lower the axle and vehicle as appropriate, then start the engine and allow the air suspension to inflate. Confirm the ride height returns to normal and tighten both shock fasteners to the vehicle's specification.
Check your vehicle’s repair manual for exact specifications and fit.
