"Probably" nothing to do with the rack and/or motor mount. I'd check the wheels first. Lift the vehicle and spin the wheels. Watch for a bent rim or a slipped belt on one of the tires. Those are the two most common problems that can cause what you describe.
If that's not it, check the half-shaft (axle) and make sure nothing is bent and that the CV joints are ok.
There is no adjustment on rack and pinion steering. If you're steering is sloppy or something I suggest you get an alignment and your front end checked.
Possible bent tierod.Have your local garage check it out.
Rack & Pinion, or just steering rack.
No. That car's design includes a rack and pinion which is responsible for the steering of the front wheels.
In order to replace a rack and pinion on a Nissan 200SX, you will need to remove the front wheels, the steering coupler, the power steering lines, and various bolts. You will then be able to remove the rack and pinion. Place the new rack and pinion in place, and return the various parts.
A bad tire with belt separation. Loose/worn steering joints. Bent rim. A warped rotor (if wobble happens while braking only).
I don't know about making the "CARD" front wheels turn, but the steering gearbox, or the rack and pinion actually cause the "car" front wheels to turn, after the steering wheel is turned. Repairing either usually involves replacing with either a rebuilt, or new gearbox or rack and pinion.
check rack and pinion. sounds like it needs to be replaced.
It is important to recognize the signs of part failure in a car. The signs of a bad rack and pinion are unusual tire wear, the steering is off, and fluid leaking from the front end of the car.
The RX8 has an electrically power assisted rack and pinion. It is located under the engine, across the front end, and (naturally) between the front wheels.
