To remove one or both of the rear arm assemblies, you should first raise the vehicle, remove the wheel and tire and move the vehicle away from the arm you want to access. After that, release the nuts, bolts and washers holding the lateral arms onto the knuckle and then take out the nuts, washers, bolt and wheel alignment cam connecting the same arms to the rear crossmember. Following this, the lateral arms should be removed from the vehicle. The lateral arm with both matching bushing sleeves should be put on the forward side of the crossmember and knuckle, so that its trimmed outer side faces backwards and carries the mark "FORWARD". On the arm with varying size sleeves, the small one should go at the knuckle and the large one near the rear crossmember so that the rear wheel alignment cam can fit correctly. If the rear arm goes to the right, the trimmed edge looks back on the couch; if to the left, it faces forward on the couch. For the first step, bring the forward lateral arm onto the knuckle and thread the short mounting bolt with a washer into them. Afterward, attach the rim to the bolt just fitted with a little bushing, along with a washer and nut, leaving it somewhat loose. Then, affix a wheel alignment adjustment cam to the threaded bolt on the top arm mount, fix the rear lateral arm to the crossmember and push the long bolt through both, so that the notch on the cam faces the ceiling. Insert the forward lateral arm in the hole of the rear crossmember, pass the long bolt through the bushing sleeve and add a washer and nut but don't over-tighten. All the bowls of the lateral arms should curve downwards, so that the trimmed edge of the right arms is directed toward the back and the left arms meet. Place the nut for the knuckle bolt behind and the nut for the crossmember bolt out in front. Replace the tire and wheel by hand first, then tighten each mounting nut to just half torque in the correct order, then tighten them again with the same order to achieve the proper 136 Nm (100 ft. lbs.). When the car is lower with the suspension at curb height, tighten the nuts holding the lateral arm at the knuckle to 95 Nm (70 ft. lbs.) and at the crossmember to 88 Nm (66 ft. lbs.). Set the rear toe to the correct amount as needed.
