Ram 1500 SLT 5.7L

• Automatic transmission
• 80,000 miles

i have a 2005 Dodge Ram 1500 Quad Cab 4WD that I bought new. At 2000 miles the transmission locked up at about 45 Mph in 2WD. The transmission was replaced but not the rear axle or drive shaft. It now has 94,000 miles on it. The rear axle has been completely rebuilt NINE times and is now failing for the 10th time. Chrysler will not rebuild it again because I took them to court and obtained a settlement. I have had the drive shaft replaced as it was finally discovered to be twisted from the first event. I use the truck to tow about 5000 pound trailers.

Is there a better axle than the one I have? I purchased a used axle with 51,000 miles on it. What can I do to make it last? I am gong to do an oil analysis on the replacement axle as well as the one that is failing. What can be causing the failure of these axles? I had the framed checked and it is slightly out of line from the lock up, but not more than a quarter inch. The failure is usually in the input bearing area. Once they installed the spacer backwards. Are these guys just incompetant and should I find a real specialist. A lot to think about. I do have a good lawyer, that's for sure. Don't let them tell you that you can't sue if you are not under the lemon law. There are many other laws you can use.
