No need for a sealed bearing. It will be obvious when you disassemble yours.
The same reason you don't use an umbrella IN the house just because it's raining outside. 
The parts inside of the rack/pinion housing are all greased. The bearings are "in the housing" - not sure how you expect dirt to get into them.
The upper pinion shaft roller bearing has a seal and the intermediate shaft dust boot covers the pinion shaft, pinch bolt, u-joint etc to the firewall.
I'll post this drawing a 3rd time so you can see that the dust cover seals the bottom of the pinion shaft housing (it's not an "open window")

I have a solution for a replacement for the 10 x 30 x 8 mm lower ball bearing. I'll get going on that. ------------------

Machining 0.5mm off each side would do it, provided it doesn't weaken the bearing races.[This message has been edited by fierosound (edited 12-24-2015).]

They really used a non-standard size at the lower end?
GM......
Maybe it was a standard size back in 84?

Just finished "rebuilding" my steering rack on my 88 GT auto. This info is invaluable to anyone repairing or refreshing the upper and lower pinion bearings. I had no idea how bad my steering had gotten until it failed me completely. With the new parts installed the car has literally transformed handling!
Thanks for the walkthrough fierosound! btw did you ever find a suitable replacement seal for the upper part of the pinion gear? I found another post showing that a seal from a 90's Honda would work. I got one from Autozone and it fit great.

Good to hear this helped. Maybe this breakdown isn't SO rare after all.

Kinda vague. A part number would be better. [This message has been edited by fierosound (edited 08-13-2015).]

Oops, yeah sorry bud. I didn't have my notes with me.
I found National part# 222028 and it's a perfect fit.

My rack had the same symptoms and when i pulled off the press on cover the ball bearings and inner cage fell out. I could only find 7 of the 8 balls. I also had to dremel out another 1mm to get the snap ring back in.

Where were you guys last year when I had my rack apart trying to find a replacement for that lower bearing?! I was trying to keep from having to widen the groove and ended up re-using the stocker (I did replace the needle bearing at the top, then found that my issue was actually in the steering column.)

This is good information for 88 owners like myself.
I will be adding this topic to my favorites.
For once, I will check my rack if I ever take it out of the car for inspection
on this issue. ------------------
