1996 Ram Van B3500
9.25 Heavy Duty rear end with a 3.92 ratio

Does anyone have any installation instructions and torque specs for installing the rear differential on a 96 ram van b 3500. The dealer said it is a 9.25 HEAVY DUTY rear end with a 3.92 ratio according to the VIN. Also, I have already replaced the carrier and pinion bearings but I am using the original pinion and ring gear. I have most of the tools Ill need except for the yoke adapter hold the yoke when final torquing the pinion nut. Any help would be greatly appreciated. Whats more is that Im wondering if all 9.25 chrysler rear ends with a 3.92 ratio are HEAVY DUTY differentials?

 

Does the 9.25 on a 3500 have a full floating axle?

 

It is not a floating axle.

 

That tool is rather expensive. I made my own out of a piece of 2"x3' angle iron from Home Depot. Scroll down to the 12th picture on this page and he shows you how to make your own tool.: http://bernardembden.com/xjs/diff/

 

Do you know the name of the tool by chance? Also, any directions for setting up the differential on this particular model would be most helpful.

 

Are you just swapping out one rear axle assembly for another or are you rebuilding yours?

 

I'm rebuilding mine. Also, I was thinking that I could use a huge pipe wrench to hold the yoke in place; I can just wedge it on the ground while I apply the 200+ ft-lbs of torque to the pinion nut.

 

You do realize that you would need a pipe wrench over 2 feet long?

 

Most of us who speed time in the garage have a welder and some way to cut stock.
Welders come with a metal scrap pile.
All you need to do is get a piece of pipe/long section long enough to reach some stop and weld a box-end of some sort on one end to fit the yoke. I normally make this one-use type tool and toss it back into the scrap pile for another recycle later.
If you want a permanent tool get a piece of 3" X 3/8" flat and cut a hole (use a 3" grinder with a cutting disk and a little filing for clean-up) in it the size for the yoke and weld on a handle; totally over-kill cause you probably will not need it again.
I thought the B3500 had an FF 9.75" dana 60, appears I was wrong!

 

I can get my hands on a pipe wrench over 2ft. long and any other tools I'll need. My biggest issue now is getting the torque specs and set-up instructions for this particular axle which is a 9.25 heavy duty rear end with a 3.92 ratio on a 1996 dodge ram van B 3500 with a 5.2 liter V8. Every thing I come across seems to be generic on the internet and I dont know for sure if that info can apply to what im workng on.
