Hey everyone, so my buddy has a ranger and is going to swap out his dana 30 that has 4.56 gears & put in a D44. I want to get ahold of the R&P if they will work for either of my xjs. I am going to check out his axle tomorrow. how can i tell the different styles of dana 30's apart and tell which one it is? I can only assume the axle is from an XJ. If it's from a cj, are the R&P compatable? Are the R&P for the low and high pinion different? sorry if these are stupid questions, i just want to learn, try not to rip me apart lol. Any help or links is greatly appreciated.
