Differential Questions
Ok. I'm 90% sure I can do this with no problems. But I wanted to run it by you guys.
2 Questions.
1) Can I take the 8.8 off my '99 Ranger and bolt it right up to the '07? (This one I'm pretty damn sure the answer is yes since the 8.8 hasn't changed for years to my knowledge).
2) Can I take the 3.73 gears out of the 99 Ranger Front Diff and install them into the Front Diff of the '07? Or hell maybe even just swap the entire differential (and not have to screw around with setting up gears). I know they changed the front from the vacuum hub setups over to a live axle setup, but I don't think that changed the actual Diff. I thought it was still that Dana 35 front end or whatever.
Hopefully someone with a bit more info can point me in the right direction. Basically, I'm looking to get a little better mileage out of the '07, so I'm getting smaller tires and I was going to gear it down to 3.73 instead of 4.10.

I only wish. I've been waiting on a friend of my dad's for going on 4 months now to help me out with rear differential (I'm stuck on the ARB).
The next time I'm home though, I'm going to get all the 44 stuff and setup in my basement back at Minneapolis so I can actually get something done. I'm so sick of people never coming through when they say they are going to help...

I'm thinking I might just take it to a machine shop soon as I know they could get it done in probably 10 minutes.

Your right. The 9" was really easy. As far as the gear setup went. What I'm stuck with is trying to tap the differential case for the air line for the ARB. I've ruined 2 different taps trying to do it and I can't figure it out. Basically, when I start turning, the threads on the tap come off, instead of digging into the differential case.

your using cutting fluid right? also try to put some kerosene in that hole as your taping it. i really hope you are using some type of GOOD taping fluid. Another good one is Tap Magic that stuff is unreal.

I may actually take you up on that. The size I need is 9/16 - 18 I believe. Let me know what kind of price you can get me (if that's alright).
