I have a 2003 Mercury Marauder (high performance Grand Marquis) 4.6L Modular DOHC V8. For the second time, I have to replace the rear axles. I tried a pair of Dorman axles because I was lead to believe they were made to be properly hardened so that the bearings wouldn‘t dig into and grind away at them, but obviously I was duped because I‘m having that same problem again 30k miles later. I want to know of some manufacturers who make good, properly hardened axles for my car so I don‘t have this problem again. I already know of Moser, but I just want to know of any others on that kind of level so I have more options. Thanks.
try a rear axle from a police interceptor panther , at least it will not break the bank , it is more than likely that either the axles were not installed true or the aluminum prop shaft having too much flexibility has distorted under power over torquing the axle
Dorman axles come from China!
