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.
