Repair Procedure 1

This procedure corrects Symptom/Condition 1 & 2 by adjusting the right and front engine mounts.

1. Verify the front driveshaft lengths (engine centering) are within specification. Measure the length from the inner edge of the outboard boot to the inner edge of the inboard boot on both driveshafts (Refer to Figure 5). This measurement must be taken at the bottom (six o'clock position) of the driveshafts while the vehicle is in a normal parked, front wheels straight ahead position.





Driveshaft Length Specifications:

2. Remove the load on the engine mounts by carefully supporting the engine and transmission with a floor jack.

3. Loosen the 2 bolts attaching the right engine mount insulator to the frame rail.

4. Loosen the screw and 2 nuts attaching the front engine mount bracket to the front lower crossmember.

5. If the driveshaft lengths are within specification, skip to step 6. Otherwise, loosen the left engine mount through bolt so it is still engaged in the threads weld nut of the rail bracket. Pry the engine right or left as required to achieve the proper driveshaft lengths. Make sure the left engine mount two piece gold color slider tube moves in relation to the aluminum core for the adjustment to be effective.





6. Position the right engine mount insulator so an outboard gap "A" of .020 in. (0.5 mm) is achieved between the outboard snubber of the insulator and the yoke bracket (Refer to Figure 6). Torque the 2 right engine mount insulator attaching bolts to 50 ft.lbs. (68 N-m).





7. Position the front engine mount isolator to achieve a minimum clearance of 0.3 in. (7 mm) on the drivers side and 0.5 in. (12 mm) on the passengers side between the isolator and the engine bracket (Refer to Figure 7).

NOTE:
IT MAY NECESSARY TO LENGTHEN THE SLOTS IN THE FRONT MOUNT ISOLATOR BY 0.1 in. (2 mm) TO ACHIEVE PROPER CLEARANCE. THE SLOTS CAN BE LENGTHENED, IF NECESSARY, BY USING A RAT TAIL FILE.

Torque the screw and 2 nuts attaching the front engine mount isolator to the lower front crossmember to 40 ft.lbs. (54 N-m).

8. If driveshaft length adjustment was required, torque the left engine mount through bolt to 55 ft.lbs. (75 N-m) and recheck driveshaft lengths.

9. Apply touch up paint to any bare metal spots.
