1. INSTALL REAR SUSPENSION SUPPORT ASSEMBLY

(a) Secure the rear suspension support assembly in a vise using aluminum plates.

NOTICE:

Do not overtighten the vise.

(b) Install the rear suspension support assembly to the rear shock absorber assembly.

(c) Apply a few drops of adhesive to the threads of a new rear support to rear shock absorber nut.

Adhesive:

Toyota Genuine Adhesive 1324, Three Bond 1324 or equivalent

NOTICE:

Only apply adhesive to the nut if it is not supplied as a precoated part.

(d) Using SST and a 6 mm hexagon socket wrench, hold the rear shock absorber rod and tighten the rear support to rear shock absorber nut.

SST: 09729-97202

Torque:

Specified tightening torque :

25 N·m {255 kgf·cm, 18 ft·lbf}

NOTICE:

Securely insert the 6 mm hexagon socket wrench into the rear shock absorber rod to prevent damage to the rear shock absorber assembly when tightening the rear support to rear shock absorber nut.

HINT:

  • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
