Rebuilding a 9.25 rear
Hey guys, Im new to this site although I have been a dodge ram owner since 2000. I am going to be rebuilding my rear differential soon and I was wondering if there was any info floating around on doing this. I have built plenty of GM differentials but never opened up a dodge. I was wondering if there was anything different such as special tools for removal or setup, specific technics unique to the Chrysler rears, certain procedures to be done or anything like that. Has anyone on this forum done a step by step on it or has a link to a step by step illustrating the rebuild?

Nope and Nope. The same theory and design are pretty much the same between Corporate GMs and Dana or Spicer axles. The only thing you really have to worry about is if it has limited slip.

Same as doing a GM corporate axle assembly. take cover off, unbolt pinion shaft screw, pull shaft & pinion gears etcout, push axles in remove toc-clips, pull axles out, unbolt case bearing mains and use a pry bar to get it out of the housing. Keep the main caps for the case on the side they are supposed to be on along with the shims. Just reverse disassembly process for assembly. Have fun.

the official Dodge FSM (field service manual in Chrysler slang)
has a very good step by step
and Hemitruckclub usually has a 2001 FSM in pdf form hosted for downloading
whose rear axle instructions should be very similar to yours.
the torsion bar out of a 1980s Chrysler K car suspension can be used as the adjustment tool, see the picture of the official tool in the link below:

good luck.
consider taking lotsa digital pictures
and doing a future post about your experience
if you live where you presently don't have experienced mechanic friends with extensive tools
consider doing a Google search for the Mopar clubs nearest you
...the people are almost always friendly and the 9.25 differential has been used for a long time...back into the 1980s
