Ford F4MY-5310-C Spring - Front

You can Select Your Vehicle to check if F4MY-5310-C fits your vehicle.

The vehicle must be raised and supported on jackstands, wheels removed, stabilizer bar disconnected (pre-1992 models), shock absorber and center link disconnected. A suitable spring compressor is installed to compress the spring, and the inner end of the lower control arm is detached from the frame. The control arm is lowered slowly to remove the spring and compressor.

For installation, set the upper insulator on top of the spring, using tape if necessary, place the lower insulator on the lower suspension arm, and install the internal damper in the spring. Place the spring between the suspension arm and the frame, with the pigtail (end of the spring) on the lower suspension arm pointing toward the left side of the vehicle. Raise the lower suspension arm into position, install the pivot bolt and nut, and tighten the nut to the specified torque.

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.

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.
