Ford BU2Z-18V125-L
Shock Absorber, Rear

Starting the replacement process for rear shock absorbers on Ford axle-equipped Super Duty F-250 and F-350 vehicles requires vehicle elevation followed by rear axle usage of an appropriate jack. After supporting the vehicle and raising it, begin by unscrewing both retaining bolts of the shock absorber. The shock detachment on F-Super Duty requires removal of the upper mounting bracket nut. The shock absorber replacement process begins with Excursion vehicles by taking off their two upper mounting bolts. An installation of the new shock absorber requires following the removal procedure in reverse and only using brand-new fasteners. The installation of shock absorbers must include identical part numbers or equivalent versions because using substandard materials can create performance problems. Proper retention of these suspension fasteners depends on following specified torque values during every reassembly step. You should treat low-pressure gas shock absorbers carefully since they run on nitrogen gas because any attempt to open them, puncture them or apply heat will be dangerous.

All vehicles are equipped with gas-pressurized shock absorbers that will extend unassisted, so avoid applying heat or flame during removal or servicing.

Remove the lower retaining nut and bolt of the shock absorber.

Ensure that torque values are adhered to for proper retention.

Specified torque values must be adhered to during reassembly to ensure proper retention of these parts.

Remove the lower retaining nut and bolt of the shock absorber.

Reverse the removal procedure and use new fasteners with the same part number or an equivalent part.
