Just spent $900 12 months ago. This is the second time the rear end/rear differential on my 2002 ram 1500 4.7, has gone out! And I don't tow or race. I love the truck, but this is a recurring problem with 2002 ram 1500's. I would like to swap out the original diff with a BETTER, stronger unit that I can enjoy. SRT 10 rear too hard? One from a 2500 better? HELP
