Hello Scotty, I have a 2011 silverado 1500 2WD STD cab 4.3 lu3 the rack and pinion is leaking has been for almost 3 years and was replaced some time just before i bought the truck which is about 3 years ago has not leaked to bad but last year used some blue devil stop leak it did help a lot but i have to keep buying it. I am ready to replace it the question is what brand to buy, i thought about gm reman but for like 800 dollars nah dont think so truck has 172,000 miles and runs great and in decent shape. I am thinking edelmann or possibly maval just not sure as you well know there is a lot of crap out there today sad even, i am 68 so been around cars and fixing most of the stuff myself if i can for years.  thanks in advance
