Re-position Propeller Shaft





23. If applicable remove four nuts and remove the tunnel brace (see Figure 18).





24. Apply an index (line up) mark across the propeller shaft and differential pinion flange for correct re-assembly (see Figure 19a).

25. Remove four nuts and bolts and carefully re-position the propeller shaft down and to one side. Use a piece of wire to support the propeller shaft to avoid excessive tension on the propeller shaft center bearing (see Figure 19b).

Disconnect Parking Brake Cables

26. Disconnect the parking brake cables as follows:





a. Remove the nuts that hold the parking brake cable brackets to the rear suspension member (see Figure 20).





b. Remove the cables from the metal support brackets (see Figure 21).

c. Remove the nuts that hold the parking brake cables to the vehicle body (see Figure 22).





d. Disconnect the cables from the front equalizer (see Figure 22).

Disconnect ABS Harness Connector/Remove Tie Wrap





27. Disconnect the ABS harness connector (see Figure 23a). Then remove the tie wrap from the suspension member using a pair of needle-nose pliers (see Figure 23b).

^ If you accidentally break the tie wrap install a new one at re-assembly. The tie wrap part number is 24225-89960.

Disconnect Shock Absorber From Knuckle





28. Place a support jack under the rear lower link. Then remove the bolt that holds the shock absorber to the knuckle (see Figure 24).





NOTE:
Do NOT disconnect the shock absorber from the body at the top of the wheel well.





29. Place an index mark across the bushing and cross bar for proper re-assembly (see Figure 26).

Install Jack Adapter Tool # J-47441-A to Differential

NOTE:
For G35 Sedan only the four main suspension member nuts must be lowered before installing the Jack adaptor. This will allow the jack adaptor to clear the spare tire wheel-well.

Rear Suspension Member Nuts

a. Support the suspension member with a jack stand near the left rear nut.





b. Lower the nut until only 1 or 2 threads are showing below the nut (see Figure 26a).

c. Lower the jack stand.

d. Perform a, b, and c above for the right rear nut.

CAUTION:
Do not completely remove the nuts.

Front Suspension Member Nuts

a. Support the suspension member with a jack stand near the left front nut.





b. Lower the nut to about the middle of its travel (see Figure 26b).

c. Lower the jack stand.

d. Perform a, b, and c above for the right front nut.

CAUTION:
Do not completely remove the nuts.

30. Install the jack adapter tool # J-47441-A to the differential pinion flange and suspension member as follows:





a. Install part "A" of the adapter tool onto the pinion flange. Make sure both pins on the tool are inserted into the pinion flange bolt holes (see Figure 27).





b. Slide part "B" of the adapter tool over the rear of part "A". Then insert the locator pins at the upper corners of the tool into the rear suspension member (see Figure 28).

Remove Rear Suspension Member





31. Use bolts to attach a transmission jack to the adapter tool (see Figure 29).





32. Place an additional support jack under the front suspension member to help stabilize the vehicle on the lift (see Figure 30).





33. Place an index mark across the coil spring and upper spring seat for proper re-installation (see Figure 31).

34. Place a support jack under the rear suspension member.





^ Then remove the bolts and nuts that hold the suspension member stay brackets (both passenger and driver's side brackets). See Figure 32.

^ Slowly lower the support jack and remove the stay brackets.

NOTE:
The larger nuts hold the suspension member.





35. Remove the bolts and nuts and remove the rear stay bracket (see Figure 33).





36. Carefully lower the suspension member (see Figure 34) and place it in a safe location away from "traffic".

Install Fuel Hoses

CAUTION:
Make sure the fuel tank is less than 114 full before you perform this procedure.





37. Remove three nuts and remove the evaporative canister shield (see Figure 35).





38. Remove and replace the four fuel hoses (provided in the kit). See Figure 36.

^ Replace hoses one at a time making sure they are correctly positioned and secured.

^ Tighten the fuel filler hose clamps so that the distance between the bolt head and metal plate is set to the proper dimension (see Figure 36).

33. Re-install all components in the reverse order of removal making sure of the following:





A. Make sure the additional support jack under the center of the front suspension member is in place and contacting the front suspension member. (see Figure 36A)





B. Raise the rear suspension assembly on the studs until approximately 1.0 inch/ 25.4 mm of the rear stud and approximately 1.25 inch /31.7 mm of the front stud is sticking through the mount.





C. Use a single nut on each side to hold the front suspension stay bracket in place.





D. Use a single nut on each side to hold the rear suspension bracket in place.





E. Use a support jack to raise one corner of the rear suspension assembly until the bushing assembly is flush to the body. Tighten the nut until the nut contacts the bushing inner sleeve.

F. Repeat the same procedure on the other side.





G. Use a support jack to raise one corner of the front suspension assembly until the assembly is flush to the body. Tighten the nut until the nut contacts the bushing inner sleeve.

H. Repeat the same procedure on the other side.

I. Torque the front and rear suspension mounting nuts to 110 Nm (11 kg-m 81 ft.lb.)

NOTE:
For removing the jack adaptor on a G35 sedan reverse the order of installation.








^ All highlighted suspension fasteners are tightened to the proper torque specification (see Figures 37 and 38).

^ All index marks that you made earlier are lined up.

^ Use new nuts/bolts (provided in the kit) for securing the propeller shaft to the differential pinion flange. Tighten the nuts to: 73.5 Nm (7.5 kg-m 54 ft-lb).

^ Use a new gasket (see Parts Information) between the front and center exhaust tubes.

40. Re-connect the negative battery cable.

41. Re-program all radio station pre-sets.
