   If there is not a good location for the GE-8001  Dial Indicator Set (2) pointer to contact the steering gear housing, install a large worm gear hose clamp (1) to the steering gear housing, and align the clamp so that the screw can be a location for the GE-8001  Dial Indicator Set pointer to contact.

6. Install the GE-8001  Dial Indicator Set (2) between the inner tie rod and the steering gear housing or the worm gear clamp (1) in such a way as to measure the lash between the inner tie rod and the steering gear housing. The lash between the inner tie rod and the steering gear housing is equal to the lash between the inner tie rod and the inner tie rod housing because the inner tie rod housing is inside the steering gear housing during this procedure.

   NOTE:

   Grasping the tire at the 3 o'clock (2) and 9 o'clock (1) positions, gently push in on one side of the tire in order to remove any lash.

8. Zero the GE-8001  Dial Indicator Set.
9. On the same side of the tire previously pushed in, gently pull out and measure the lash.
10. Record the measurement shown on the GE-8001  Dial Indicator Set.
