Removal and installation the front suspension strut assembly (BMW 5 Series E28)

Removal

Although strut assemblies do not always fail at the same time, replace the left and right struts in pairs to prevent possible handling or ride problems.

1. Loosen, but do not remove, the front wheel mounting bolts.

2. Jack up the front of the vehicle and securely place it on axle supports.

3. Remove the front wheel.

4. Disconnect all brake hoses and electrical wires leading to the suspension strut housing.

5. Disconnect the electrical connectors from the ABS system, if equipped.

6. If you are removing the left strut, disconnect the electrical connector from the brake pad wear sensor.

7. Loosen the ABS wheel sensor mounting bolt, if present. Remove the brake disc (see chapter Brake system).



8. Give these three bolts (indicated by arrows), and remove the brake mechanism splash guard.

9. Disconnect the stabilizer bar link from the strut housing (see section Removal and installation the front stabilizer).

10. Loosen the bolts securing the pivot arm to the strut body.

11. Pull out the bottom of the strut housing enough to allow access to the end of the pivot arm.

12. Support the strut and loosen the three mounting nuts at the top of the strut located inside the engine compartment, then remove the strut.





13. Remove the strut assembly. If the strut needs to be replaced (or shock absorber cartridge), see Section Replacing a strut or shock absorber/coil spring.

Installation

Install in reverse order. Make sure the tab on the pivot arm aligns with the recess in the rack housing.

BMW recommends using a special thread lubricant on the pivot arm mounting bolts. For all models, tighten the fasteners to the specified torque.

After completing the work, check the front wheel alignment angles at the dealer service department or auto repair shop and adjust them if necessary.
