NOTE:

If a bonded rubber bushing is faulty, then the bonded rubber bushing on the opposite side must also be replaced.

Check the other bushings before replacing a faulty bonded rubber bushing.

If cracks, oil leaks or other damage is visible, this bonded rubber bushing must also be replaced.

Two different front bonded rubber bushings were installed during production, a conventional bushing and a hydraulic bushing, refer to BONDED RUBBER BUSHING .

-- Place the vehicle on a hoist.

-- Remove the wheels.

-- Remove the coil springs, refer to COIL SPRING, REMOVING AND INSTALLING .

NOTE:

In order to replace the rubber bonded bushing, the subframe must be lowered either at the front or at the rear. It is not necessary to remove the subframe.

Lower the subframe alternating between the front and rear. This avoid having to perform an axle alignment.

Do not lower the subframe more than 4 cm.

Identify mounting location to subframe before removing the bonded rubber bushing.

Replace the front bonded rubber bushing or the front hydraulic bonded rubber bushing.
