Service Procedure
CAUTION:MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON HOIST. TO HELP AVOID PERSONAL INJURY, PROVIDE ADDITIONAL SUPPORT TO THE OPPOSITE END OF THE VEHICLE THAT COMPONENTS WILL BE REMOVED FROM.
1. Raise vehicle on a hoist.
2. Remove right front wheel and tire assembly.
3. Remove right upper wheelhouse panel.
4. Lower vehicle enough to allow underhood access to engine mount.
5. Remove two engine mount-to-midrail bracket nuts.
6. Place a floor jack under engine oil pan (use a block of wood between oil pan and jack). Raise powertrain just enough to unload the mount to gain access to the fasteners. (Engine is raised enough when there is clearance between the mount and midrail bracket.)
7. Remove the three engine mount-to-front cover nuts and discard.
8. Remove engine mount.
NOTICE:
If the engine mount front cover stud turns or comes out during nut removal, the stud must be fully installed prior to installing the mount and/or nut. Damage to the front cover may occur if the stud is driven with the nut and does not sufficiently engage the front cover threads. Refer to step 9 for correct engine mount front cover stud(s) installation. If stud(s) did not come loose continue with motor mount bracket service procedure, step 11.
IMPORTANT:
Loctite 242(R) or equivalent is not required on studs during installation.
9. If nut and stud was removed as one unit, the old nut must be removed from the stud and the nut discarded.
10. Re-install stud(s).
Torque:
Engine Mount Stud: 10 N.m (89 in-lbs)
11. From engine side of bracket, remove four bracket-to-midrail fasteners.
12. From wheelhouse side of bracket, remove three bracket-to-midrail fasteners and remove bracket, discard old bracket.
13. Obtain new replacement engine mount bracket.
14. Position bracket to midrail.
15. Hand start all seven fasteners. (Four fasteners attach from engine side of bracket, and three fasteners attach from wheelhouse side of bracket.)
16. Tighten all fasteners, a crowfoot wrench may be necessary.
Torque:
Midrail Bracket Fasteners: 32 N.m (24 ft-lbs)
IMPORTANT:
Install ground strap to stud on intake manifold side before installing new nut.
17. Position engine mount to front cover and install new nuts.
Torque:
Engine Mount-to-Front Cover
Nuts: 50 N.m (37 ft-lbs)
NOTICE:
When lowering the powertrain, it will be necessary to guide the mount over the midrail bracket studs to prevent damage to the stud threads.
18. Lower powertrain completely.
19. Install new engine mount-to-midrail bracket nuts.
Torque:
Engine Mount-to-Midrail Bracket
Nuts: 50 N.m (37 ft-lbs)
CAUTION:
MAKE SURE VEHICLE IS PROPERLY SUPPORTED AND SQUARELY POSITIONED ON HOIST. TO HELP AVOID PERSONAL INJURY, PROVIDE ADDITIONAL SUPPORT TO THE OPPOSITE END OF THE VEHICLE THAT COMPONENTS WILL BE REMOVED FROM.
20. Raise vehicle on a hoist.
21. Loosen the two engine strut bracket-to-frame fasteners to remove any fore/aft preload from the engine strut.
22. Tighten engine strut bracket-to-frame nuts.
Torque:
Engine Strut Bracket-to-Frame
Nuts: 50 N.m (37 ft-lbs)
23. Install upper wheelhouse panel.
NOTICE:
Before installing wheels, remove rust or corrosion from wheel mounting surfaces and brake rotors/drums. Failure to do so can cause wheel nuts to loosen in service.
24. Position right front wheel and tire assembly onto hub.
25. Install wheel nuts and tighten in a crisscross pattern. Repeat tightening pattern to ensure torque is correct.
Torque:
Wheel Nuts: 140 N.m (103 ft-lbs)
26. Lower vehicle from hoist.
27. Affix Campaign Completion Label on a clean and dry surface of radiator core support, in an area clearly visible when hood is raised. (For more information, refer to "CAMPAIGN COMPLETION LABEL" in this bulletin.)
