General information
1. These bearings do not require attention often, however, a damaged or broken bearing must be replaced immediately. Otherwise, the loads occurring in the power transmission may cause damage or wear.
2. The supports can be removed and installed separately. However, if several supports need to be disassembled, such as when removing the power unit, then such a removal and installation procedure must be performed in a strict sequence.
3. During installation, the weight of the power unit must not be transferred to the supports until all of them are correctly aligned. Install the Ford special device in place of the front support and tighten the fasteners of the power unit support to the required torque in the sequence specified in paragraphs 49-50, paragraph 4, chapter 2B.
Inspection
4. When inspecting, the power unit must be slightly raised so that its weight is not transferred to the supports.
5. Raise the front of the car and place it on supports. Place the jack under the pallet and, placing a wooden pad between it and the jack head, support the power unit to hang it.
Warning: If the engine is supported only by a jack, you must not work under it!
6. Inspect the bearings for cracks in the rubber, hardening, or separation of the rubber from the metal part. Sometimes the rubber will crack right under the center.
7. Check the possibility of relative displacement of the bracket of each support and the power unit or body. To do this, move the supports with a power screwdriver or lever. If the displacement is noticeable, lower the engine and check the tightening (with a torque wrench) of the support fasteners.
Replacement
Note: The following assumes that the engine is supported by a jack (as described above).
Front support (roll limiter)
8. Remove the resonator support bracket bolts from the front crossmember of the engine compartment. Loosen the two clamp screws securing the resonator to the air flow meter and prechamber hoses. Then move the resonator away from the thermostat housing (see Chapter 4). Remove the afterburner filter housing bolts from the support bracket. Then remove the bolts/nuts securing the support to the subframe. Remove the central bolt and remove the support. Note the position of the wiring connector bracket. If necessary, the support bracket can be removed from the transmission by unscrewing its bolts (see Fig. 23.8).

9. When installing, tighten the support mounting bolts to the transmission securely, and then install the support and the wiring connector bracket. First, tighten the support mounting bolts and nuts to the required torque (in two stages). Then tighten the support center bolt to the required torque.
Right support
10. Unscrew the nuts and remove the bracket, taking into account which of the nuts are self-locking (they should always be replaced after unscrewing). Unscrew the bolts securing the support to the body (see Fig. 23.10).

4. Body
11. If a hydraulic support is installed, the bracket is secured with five nuts. The support can be recognized by its shape. It should never deviate from the vertical by more than 5° (see Fig. 23.11). On models produced since 05.1998, the cross bracket is not installed, and one of the body bracket mounting bolts also secures the cooling system hose bracket (see Fig. 23.11, b).

12. When installing, replace the self-locking nuts and tighten the fasteners to the required torque. When tightening the nuts, first tighten the four nuts securing the bracket to the engine, then lower the power unit onto its supports with a lifting mechanism. When tightening the remaining two nuts, the support should not swing (see Fig. 23.12).
Left support
13. Disconnect the two wiring connectors, disconnect the vacuum hose (if equipped), disconnect the crankcase ventilation hose from the cylinder head cover and remove the air cleaner assembly together with the air flow meter, resonator and pre-chamber (Chapter 4).
14. Remove the three nuts to release the support from the transmission, then remove the support bolts from the body (see Fig. 23.14). Note that the nuts are self-locking and should always be replaced after being removed. Remove the central bolt to disassemble the support and replace the components if necessary.

15. When installing, replace the self-locking nuts. When tightening the nuts, do not allow the support to swing (see Fig. 23.15). Tighten all fasteners to the required torque.
Rear support (roll limiter)
16. On models with automatic transmission, a separate damper may be installed under the subframe, the bolts of which must be unscrewed to access the support fasteners (see Fig. 23.16).
17. Remove the support bolts from the subframe. Then remove the central support bolt. If necessary, remove the support bracket bolts from the transmission (see Fig. 22.17, a, b).
18. When installing, tighten the support bracket mounting bolts to the transmission securely. And then install the support. First, tighten the support mounting bolts to the subframe (in two stages to the required torque). Then tighten the center support bolt to the required torque.
