Procedure
- With the lock carrier installed, the engine is removed downward with the transmission and subframe.
- Install cable ties at the same locations when installing.
- Pay attention to the guidelines for clean working conditions. Refer to GUIDELINES FOR CLEAN WORKING CONDITIONS .
- All bolts on suspension components with bonded rubber bushings must be tightened in curb weight position (no load).
- Bonded rubber bushings have a limited range of rotation. Axle components with bonded rubber bushings must be brought into the position they will be in when driving before they are tightened (curb weight position). Otherwise, the bonded rubber bushing will be under stress, which will reduce the service life.
