      Because the nut has its own stopper, do not turn the nut. Loosen the bolt with the nut secured.

  5. REMOVE FRONT LOWER NO. 1 SUSPENSION ARM SUB-ASSEMBLY RH

    Tech Tips

    Perform the same procedure as for the LH side.

  6. REMOVE FRONT NO. 2 SUSPENSION MEMBER DYNAMIC DAMPER (for 2GR-FKS 2WD)


    1. B007Z4J

      Remove the 2 bolts and front No. 2 suspension member dynamic damper from the front frame assembly.

  7. REMOVE FRONT SUSPENSION MEMBER DUMPER PLATE (except 2GR-FKS AWD)


    1. B007YD9

      Remove the 2 nuts and front suspension member damper plate from the front suspension member dynamic damper.

  8. REMOVE FRONT SUSPENSION MEMBER DYNAMIC DAMPER (except 2GR-FKS AWD)


    1. B007XNZ

      Remove the 3 bolts and front suspension member dynamic damper from the front frame assembly.

  9. REMOVE FRONT SUSPENSION MEMBER BODY MOUNTING FRONT STOPPER


    1. Remove the 2 front suspension member body mounting front stoppers from the front frame assembly.

  10. REMOVE FRONT SUSPENSION MEMBER BODY MOUNTING REAR STOPPER


    1. Remove the 2 front suspension member body mounting rear stoppers from the front frame assembly.

  11. REMOVE FRONT SUSPENSION MEMBER BODY MOUNTING FRONT CUSHION LH


    1. B007Z0UC02
      *1 Front Suspension Member Body Mounting Front Cushion LH

      Install SST as shown in the illustration.

      SST
      09830-10010   ( 09830-01010, 09830-01040, 09830-01050 )
