Mercury F8AZ-5560-CA Spring - Rear

You can Select Your Vehicle to check if F8AZ-5560-CA fits your vehicle.

Loosen the wheel lug nuts, raise the rear of the vehicle and support it securely on jackstands placed under the frame. Remove the wheel and block the front wheels. Remove the rear stabilizer bar. Support the rear axle assembly with a jack placed under the axle housing. Position a safety chain through one of the spring coils and around a convenient frame member. This will prevent the spring from flying out before it's fully extended. Unsnap the right parking brake cable clip from the right upper suspension arm. Disconnect the lower studs of the two rear shock absorbers from their mounting brackets on the axle tube. Detach the height sensor connector link from the upper control arm. On 1998 and later models, the lateral arms that are part of the Watts linkage must be disconnected at the chassis ends. Slowly lower the jack until the spring is fully extended. Remove the safety chain, coil spring and insulators from between the suspension arm and the spring upper seat. Set the upper insulator on top of the spring, using tape to hold it in place, if necessary. Place the spring between its seat on the axle tube and the frame seat, so that the pigtail (the lower end of the spring) is pointing toward the left side of the vehicle. Raise the axle assembly with the floor jack and insert the studs on the lower ends of the shocks into their holes in the brackets on the axle tubes. Install the stud retaining nuts, but don't fully tighten them yet. Snap the right parking brake cable into the upper suspension arm retainer. Install the rear stabilizer bar. Connect the height sensor connector link to the upper control arm. Remove the jackstands and lower the vehicle. Before attempting to drive a vehicle equipped with air suspension, turn the air suspension switch to On, start the engine and allow the compressor to inflate the air suspension springs (they deflate automatically when the rear of the vehicle is raised).

This procedure specifically applies to 2002 and earlier models. Coil spring removal and installation on 2003 and later models are combined with shock absorber replacement.
