Ford 6W7Z-5560-B
Coil Spring, Purple, Rear

A vehicle must be in NEUTRAL gear positioned on a hoist before starting rear coil spring removal or replacement operations. After disassembly of stabilizer bar links through their bushings and nuts you can free the stabilizer bar from its position on those links by rotating it away from the links. Use appropriate jack supports to secure the rear axle before removing lateral arm frame attachments with their corresponding bolts and nuts along with their replacement fasteners. The vehicle contains shock absorbers with pressure-filled gas that expands automatically without manual intervention; therefore avoid using heat or flame on them. The shock absorbers need their nuts and bolts removed to disconnect from the axle before discarding the old fasteners. Lower down the jack or jack stands carefully while removing the springs together with their spring insulators. Check the mounting brackets of the spring insulators and replace them with new ones if needed. Set the spring insulators on top of the vehicle springs then position them correctly inside the vehicle before lowering the axle with the jack holds. After raising the axle using the jack stands or jack, attach the shock absorbers to the axle using new bolts and nuts while inserting the bolts through the inboard side followed by a 90 Nm (66 lb-ft) nut torque. Install fresh bolts along with nuts between the lateral arms and frame while keeping them loose for now. Fire up the jacks until the axle reaches its appropriate position and follow by tightening both lateral arm-to-frame bolts to 90 Nm torque (66 lb-ft torque). Lower down the axle then remove both the jack and jack stands. Wrap up stabilizer bar installation by placing it on stabilizer bar links then inserting bushings before torquing nuts to 20 Nm (15 lb-ft). Repower the vehicle after installing the system when it includes a fire suppression system.

Install the new upper ball joint nut and tighten it to 150 Nm (111 lb-ft).

Do not remove the center nut that holds the upper spring mount in place, as this will release spring tension.
