|Installation of your Unobtainium Motorsports rear bushing kit is
fairly straight forward. Please refer to the illustrations above
and in the body of these instructions in order to simplify the identification
of the parts in your kit and their installed locations.|
|1. Refer to the Mazda 3rd
generation RX-7 Shop Manual for instructions on the removal and replacement
of the rear suspension
components. Torque values for the suspension bolts will be listed in the
shop manual. Please follow those instructions precisely to
ensure correct installation of the suspension components.|
2. Once the suspension components have been removed from the car, use a hydraulic press to press out the OEM rubber bushings, or have a machine or suspension shop perform this service for you. Please note that it is not necessary to remove the rear lower control arms from the car to complete the installation of your bushing kit. Only the rear upper control arms and rear trailing arms need to be removed.
IMPORTANT: Do NOT remove a bushing in any location other than those indicated by the labels a, b, or c in Fig. 1 and Fig. 2 above. The rear suspension kit bushings are intended to replace ONLY the bushings indicated by those labels. The other bushings in the rear suspension are "pillow ball" bushings, and they provide a much wider orbital range of motion than a standard bushing. The pillow ball bushings are metal-on-metal by construction, so replacing them is unnecessary unless they are excessively worn, and would not improve the function or stiffness of the suspension. In the event that they are excessively worn, please have them replaced with OEM Mazda parts.
3. The center pins in your kit are intended to be a loose fit and will not be installed with the nylon bushings when they are pressed into the suspension components. Set the center pins aside, since they will not be installed until you are ready to replace the suspension components on the vehicle.
4. There are three different styles of bushings in the rear bushing kit, as shown in Fig. 3 below. Although the height of the bushings in the kit are very similar, the four that are noticeably largest in diameter are for the rear upper control arms, and are labeled a in Fig. 3 and Fig. 4 below. Their position is illustrated in Fig. 1 above as a, two bushings for each upper control arm. Press these bushings into the upper control arms in position a in the direction of the arrows in Fig. 1 above, so that the flanged ends of the bushings face outward, in the opposite directions of the arrows.
