After talking to a technician at BBB industries he said that the grooves will be there on some of the higher mileage units. They rebuild about 60% of the rack and pinions in the US and he said that they will take a hone to the ones that look questionable. He said that his company has the ability to sleeve them, but the Magnasteer ones they don't because of the magnet unit prevents them from doing that and usually just throw them away and find a better core to rebuild.

We ended up using a small hone and resurfaced it. The grooves almost disappeared.
The bearing on the end of the pinion shaft we could feel a bit of a catch when rotating it. After looking up the numbers on the bearing, it was discovered as an oddball bearing and only found over seas and in amounts of 10. It measures 10x30x8mm.
However after checking with my local bearing supply, they had one that matched all but one dimension. This is going to be resolved by using a 30mm centerbore bit to remove 1mm of material to allow the new bearing to seat properly below the locking ring. I found a centerbore bit from Amazon for about $15.00. Not sure if this will do the trick, but we are gong to give it a try.
