Make certain all the components, especially the mounting surfaces, are free from debris before starting to assemble your rear strut. Put the spring in such a way that the sleeve faces upward as instructed by the manufacturer. Put the spring in the position recommended from disassembly to simplify assembly. Put the lower spring isolator on the strut, then line up their steps. Put the strut down through the bottom of the coil spring and stop when the bottom spring seat reaches the spring's lower end, aligned with the step in the lower seat. Now, hold it in place with a clamp. Then, fit the jounce bumper under the dust shield from underneath and make sure it locks into place above. Place the dust shield and jounce bumper in the bottom of the upper strut mount and snap the dust shield into place, so it can rotate without coming undone. Install the upper mount, dust shield and jounce bumper on the strut shaft so that the center rear mounting stud lines up with the stabilizer bar attaching link bracket. First install the top strut mount onto the strut shaft, using the strut shaft nut and a Strut Shaft Socket, Special Tool 6864, to stop the shaft from turning as you screw the nut on to 75 Nm (55 ft. lbs.). With the release of tension, back off the compressor and synchronize the upper mount, spring and strut again. Also, remove the clamp from the lower end of the coil spring and strut, roll back the spring compressor hooks and take out the strut assembly from the compressor.
