Toyota 48790-14010 Arm Assembly Upper Control Rear Left

The process describes the operations regarding the displacement and attachment of the rear suspension arm coupled with the rear brake component but with the fixed stub axle assembly. First of all, unscrew the rear stabilizer bar from the suspension arm also, there is the drive axil which has to be unscrewed from the stub axil. Then remove the brake hydraulic line and parking brake cable from the reel of the rear brake assembly. Disengage the shock absorber and the coil spring; make sure that the suspension arm is held up by a jack when removing the pivot bolts nuts. Since toe-in is to be adjusted through the inner pivot bolt's adjusting cam, its position needs to be noted before removal. In the case of suspension arm pivot bushings becoming worn or damaged beyond the recognised limit then they will need to be changed. Thus, for new bushings, it is necessary to cut off the end flange tips while bending the remaining section out as shown in Fig. Rest the inner flange face of the suspension bushing eye on a steel tube, then tap the bushing through with a large socket on a hammer. Finally, the removal of the bushings proceeds in the reversed order, and they are not lubricated. On tightening the suspension arm, ensure that the index and toe-in cam marks are lined, although the pivot bolts should not be over tightened at this point. Lower the vehicle and check the suspension droop after fitting of coil spring and shock absorber, and then bounce the vehicle to settle the suspension before tightening the pivot bolt and the shock absorber lower mounting bolt to the using torque. Last but not the least, release the brake hydraulic system and maybe have the rear wheels alignment done by a professional.

Install the lower suspension arm(s) but do not tighten the nuts completely at this time. Align the matchmarks made on the adjustment cam(s) and subframe.

Have the front end alignment checked at a dealer service department or alignment shop.
