Subframe support bushings

Note:

• The front cross member support bushings of the subframe are guides.
• Make sure the support bushings are oriented correctly when installing.

1. Remove the subframe (see chapter "Engine - mechanical part").



2. In two places on the upper surface of the subframe cross beams and the upper surface of the corresponding support bushings there are marks (in the form of arrows) indicating the installation direction.

3. When installing the support bushings into the inner tubes of the front subframe cross member, align the direction of the arrow on the bushing with the direction of the arrow on the subframe cross member.

Note: Before installation, check that the arrow on the support sleeve is parallel to the arrow on the subframe crossmember. Make sure that the direction of the arrow on the installed support sleeve deviates no more than ±3 degrees from the direction of the arrow on the subframe crossmember.

4. The subframe is installed in the reverse order of removal.
