NA Miata Steering Rack Bearings

If you’re depowering or rebuilding the power steering rack in your NA Miata and want to replace the pinion bearings these are the part numbers, at least for a 1990.

For the upper bearing an 1116 socket works great to press it out of the seal housing. You’ll likely damage the rubber seal doing this but you can find a replacement in a rack and pinon seal kit. I used a sealed bearing (6804DD) for additional protection from the elements, but it’s open from factory.

The lower bearing is not press fit and should come out with minimal effort.
