Ford 4F2Z-5310-BA
Coil Spring, Front

To maintain coil springs start by removing shock absorbers and assembly units. Create index marks to use later on both the mount and spring and shock absorber unit. You need to use a proper spring compressor to compress the spring after which you can remove the shock absorber shaft nut by placing a suitable pass-through socket wrench onto the strut shaft nut followed by a 10-mm 6 point deep well socket on top of the strut shaft. Take out the strut shaft with the nut fixed in place before tightening it to 90 Nm (66 ft. lbs.). Verify the new spring part number with data from the vehicle certification label spring code by converting it to the appropriate part number through Vehicle/Application and ID. The front end alignment must be checked during reassembly as technicians need to apply specified torque values for critical suspension fasteners to ensure retention. All fasteners require parts with identical numbers or equivalent parts to prevent performance problems.

Position it on the rear axle assembly and press it into place, ensuring it is correctly seated.

The vehicle should be in NEUTRAL and positioned on a hoist.

Remove the shock absorber lower bolt and nut, noting that the spring insulators may come out with the spring during removal.

Do not allow it to hang from the flexible hose; instead, provide suitable support to avoid damaging the parking brake cable.

Overextension of the tripod CV joint can lead to internal part separation and axle shaft failure.

Tighten them to 35 Nm (26 ft. lbs.).

Ensure the part number is correct.
