8.8 rear end upgrade
 
I am getting ready to install an 8.8 into my 93 yj wrangler. I just got this jeep and it is very nice with a recent proper paint job very clean and in good condition... i promply blew up the 35 p.o.s rear end which a previous owner put an air locker into a few years ago... the first thing i learned is that it is cheaper to junk yard an 8.8 and build it with an air locker than it is just to put an air lock carrier in a 35... not including labor and perches of course
ok my first question is: what year exploder (ford explorer) do i want to get the rear end out of?... my best guess so far is 1999... I hear 97 or newer to get the disc brakes... but is there an exact year i want?

I want to change to leaf over at the same time... any suggestions? are there any stock manufactured leaf assy in existence that will work -and can be junk yarded? I also heard that the ride is hella better like night and day with leaf over... is that true?

I have heard that the ford rear end is 2 inches wider than the dana 35 is this true?


the rig has a nice compressor and tight lighted rocker switches nicely positioned on the dash panel so i will be staying with air. i hear that the stock front end is plenty rugged enough so i will leave it alone. It has 456 but i will not be building the rear carrier unit (air locker carrier) until later date because i want to run 410 to see if it will push the tires (33's). I am currently looking for the cheapest way to obtain a 8.8 with 410 rp ... but i dont know rear ends yet... How do I get a good one? what am I looking for other than heavy gear wear and too much axle end play? I will probably buy the generic tech manual for rear ends and educate myself but somebody please tell me what the heck is back lash I am dying to know...:doh:

btw the reason the rear end blew is some knuckle head did not hang the angle correctly and I am the guy who learned the hard way that vibrations in a drive line are death... the yolk failed and crashed the carrier taking the spiders and the ring completely out... i was astonished to see the chicken sh** c clips that hold the axles in a dana 35... but I hear that exploders have c clips as well just heavier... I already know about welding the tubes to the housing thanks to this forum but what else should I know???? I will post my progress and decisions through this whole project and continue to post as i build up the 4.8 that i am going to build for it starting with the 1993 block and stroker crank that i already have... this is why I want to see if 410 feels ok

My goal is to have a grocery getter weekend driver that hauls ass on the pavement with a lot of low end (hiway not dirt) torque and a somewhat extended rpm range like a brittish car, but will also go dirty nicely when needed.

I just want to make it run again 2wd for now will talk about that engine later... would love to hear anything you guys feel or think... and if anyone has an 8.8 for sale or 456's for 8.8 im interested

1995 to 2000ish explorers have the disc brake 8.8 with 31 spline shafts. Try car-parts.com for local yards in your area. See if you can get one with the calipers on it, as they are not cheap to buy with out core returns. The 8.8 is narrower vs the dana 35 but not enough to make a major difference. I have the ruff stuff products spring pads and hanger for my 8.8 going on in a few weeks. I will be running 4.11's on 33's but I have the auto trans in my 95.

Here is a good definition of "backlash" and how to measure it; Setting Backlash

I bought my 8.8 off craigslist from a private party for $125. Out of a 2000 Ford Explorer. Pulled it myself and saved the U-bolts, spring plates, brake lines, brake cables and drive line. The one I got was a 3.73:1 LSD. Soon to be 4.56:1 w/ARB.:thumb: They're out there, lots of them. The 4.10:1 model is probly the rarest of them. And you'll pay more for them, usually.:cool:
