When I installed the rack, I had to install the T3 manual rack adapter bushing to retain the power steering rack bracket. However, I didn't replace the other "D" shaped bushing. My friend Greg had duplicates lying around from this Prothane bushing kit for his mr2.
Since the engine is out and the 20v is on hold until I get an engine hoist, it seemed like a good time to hopefully solve the steering issue.
Now that the new bushing is installed the rack seems much stiffer. After installing these I realized how crucial they are to the steering input on the ae86. Being that the bushings are $30 for both this is a modification that all ae86 owners should not overlook. Have a nice day.
