Suspension Crossmember, Rear

The removal process of AWD rear suspension member starts by taking off rear wheels and the center exhaust pipe assembly. Begin by taking off the propeller assembly with center bearing shaft followed by dividing the left and right rear speed sensors after detaching their bolts. The next step is to remove nuts from the rear axle shafts before disconnecting the assemblies of No. 3 and No. 2 parking brake cables. The repair process starts by taking off No. 1 floor under cover and both rear strut rod assemblies and the rear height control sensor sub-assembly whenever HID headlights exist with the system. Hence remove both rear No. 2 suspension arm assemblies while moving on to separate the rear No. 1 suspension arm assemblies. The mechanic should drain differential oil followed by removing rear drive shaft assemblies with their attached snap rings from both sides. The procedure requires disconnecting the connectors then unclipping clamps on the frame wire and No. 3 floor wire. A jack equipped with three wooden blocks should support the rear suspension member while technicians remove four nuts, two bolts and two rear lower suspension member stopper retainers before lowering the member with caution to prevent damage. Start by discarding the rear No. 1 suspension arm assemblies followed by removing the rear differential carrier assembly with its differential support and finishing with the rear No. 1 and No. 2 differential mount cushions. To detach the rear suspension member body mounting front cushion on the LH side utilize Special Service Tool: 09830-10010 applying grease to the tool threads and tighten it gradually. Perform this sequence once again on the RH side. Special Service Tool: 09710-30050 allows removal of the rear mounting cushions after applying the same care as previous steps while the cushions should be removed when they reach 6 mm in projection. The procedure ends by taking out the hole plugs along with rear No. 2 body mounting bracket sub-assemblies from both sides and the stud bolts from each side.

The process to replace the rear suspension member for AWD begins by taking away the rear wheels and the center exhaust pipe assembly followed by removal of the propeller with center bearing shaft assembly. Start by dismounting both rear speed sensors after undoing their bolts and check for debris in their tips as well as installation openings. The repair process starts with removing both rear axle shaft nuts before separating the cable assemblies which contain No. 3 and No. 2 parking brake components. Proceed to eliminate the No. 1 floor under cover along with rear strut rod assemblies from both sides and the rear height control sensor sub-assembly when HID headlight system is present followed by removing the rear No. 2 suspension arm assemblies. Both sides require separation of their rear No. 1 suspension arm assemblies while operators drain differential oil and detach rear drive shaft assemblies with their snap rings. The procedure involves removing the No. 3 floor wire and the frame wire by both connector disconnection and clamp disengagement. A jack with three wooden blocks should support the rear suspension member before removing four nuts and the two bolts and two rear lower suspension member stopper retainers so that the member can be lowered with caution to prevent any damage. First disconnect rear upper suspension member stoppers then take away rear No. 1 suspension arm assemblies from both sides. You need Special Service Tool: 09830-10010 to eliminate the rear differential carrier assembly with differential support alongside the rear No. 1 and No. 2 differential mount cushions together with the rear suspension member body mounting front cushions from both sides. Apply grease on the threads before tightening each bolt gradually. To gain access to the rear suspension member body mounting rear cushions on both sides employ Special Service Tool: 09710-30050 according to the same safety measures. The hole plugs together with the rear No. 2 body mounting bracket sub-assemblies on both sides and the stud bolts on both sides need to be removed.

Install the rear strut rod assemblies for both sides, then install the rear height control sensor sub-assembly and the No. 3 parking brake cable assembly, tightening with specified torque values. Repeat the same procedure for the No. 2 parking brake cable assembly.

Finally, install the rear wheels with a torque of 103 Nm (1050 kgf-cm, 76 ft-lbf), stabilize the suspension, fully tighten the rear No. 2 suspension arm assemblies LH and RH, inspect and adjust the rear wheel alignment, check for the speed sensor signal, initialize the height control sensor signal if equipped with HID headlight system, and inspect and adjust the headlight aiming.
