Engine Angle (Except LS)
WARNING:
On vehicles with electronic air suspension, suspension system MUST be disabled prior to hoisting or jacking. See DISABLING ELECTRONIC AIR SUSPENSION
under MAINTENANCE.
NOTE:
Ensure all engine and transmission mounts are in good condition before performing this procedure.
- Rotate drive shaft until transmission yoke ear is parallel to floor. Place protractor flush against ear on yoke. If slip yoke is not machined, place protractor or equivalent against bottom of starter. See Fig 1 . Measure and record reading. Subtract frame angle from obtained reading to attain engine angle.
- If engine angle is greater than specification by one degree or more, loosen but DO NOT remove engine and transmission mount fasteners. Tighten engine and transmission mount fasteners. Repeat step 1 . If angle is still out of specification, install shims under transmission mount and rear crossmember until correct angle is obtained.
