I really wanna know how you have an 2003 Ram rear with drum brakes; discs were standard on the 1500 since 2002. Have pics? Sounds like the rear was replaced at one point in it's life with the wrong one.I have an 03 ram with 3.92 gear ratio with drum brakes. (no good)
I purchased a 04 rear end with 3.92 ratio with disc brakes. ($150.00)
The obvious question here is whats the best solution to make the new rear end work on my truck.
