RAISING THE REAR OF THE
VEHICLE

1: Block the front wheel.

2: Place a jack at each corner of the rear frame or

use an overhead hoist with dual chains or straps

connected at the corners of the rear frame.

3: Raise the vehicle to the height required by the

procedure being performed.

4: Use jack stands if any part of your body must be

under the vehicle at any time or, if the vehicle

must remain suspended while unattended.

NEVER lift both rear wheels off of the ground using

a single lift point.
The vehicle shall ALWAYS be supported at three

points. When raising the rear wheels off of the

ground, the 3-points would be the front wheel and

2-points at the rear on the left and right side furthest

apart.
Failure to support the frame at three points may

result in tipping of the vehicle causing severe bodily

injury and/or property damage

WARNING

This section is one section of a complete service

manual. Before starting any procedure, read all

warnings and instructions that are located in the

Service Guidelines chapter.
