Question Leaking Fluid through Magnasteer Pinion on Rack

Hi All,
I've had enough with PS fluid under the 99 Lesabre Custom. I discovered the fluid is coming from where the steering linkage meets the rack. In this model I think this is the magnasteer device. I do not suspect an internal leak at this time.

Is it possible to fix the leak without removing/replacing the rack. Perhaps by replacing a seal around the pinion?
If not possible please recommend a good re-manufactured rack.

Thanks in advance,
RW

Replaced the original rack with a remanufactured one from O'Reilly. The rack did not inspire confidence being crudely sprayed with black paint and no country of origin sticker (but I can assume..). It did work though for a month and then began leaking worse than the original and in the same spot. I estimate it leaked 4 ounces a day which is a huge percentage of the total capacity. My parking space looks like I changed the oil without a pan. I contacted O'Reilly who ordered another one (warrantee) which looked much better. No cheap black paint spayed haphazardly. The new one came with replacement o-rings and instructions. It has been a week and no leaks. Need to get the Magnasteer recalibrated but Iím happy for now.
Don't attempt this job without a lift. The first replacement took a full day and the second took 5 hours so I'm getting better.

Followup - I spilled so much PS fluid in this area that I suspect it damaged the speed sensor because the speedometer started bouncing erratically. These cost about $20 on ebay and are easy to replace. Maybe this will fix it. I'll let you know.

Looks like I need to swap out a rack and pinion myself. Just curious how you went about doing it in 5 hours. Did you remove the exhaust ?? The last time i did this, I took the sway bar loose and lowered the front subframe enough to get the rack out the drivers side wheel well. It took me considerably longer than 5 hrs.
