is the 8.8 swap really that hard ?

I have a 92 wrangler with the 2.5. I'm running 33s with a 4" suspension lift. I wanted to upgrade the back Axel because everywhere I read ppl say stock won't last.,

It's not hard at all. The challenge is taking the time to do the research. The cost depends on how much you can do yourself

Its too easy if you can weld or know a buddy that can. Its not rocket science, simple measure once, measure again and bam its done.
Lots of write ups on here that walk you thru it. Cost for my last one was 75 for complete axle assembly at the U pull it yard. ( i found the right ratio then found one with new brakes and rotors and put the 2 together. I only grind off the perches and reuse them so that was basically free. Then I reuse the ford U bolts cause they nice. The yoke adapter is already on the vehicle you taken the 8.8 from so get that and leave attached so yard not charge extree. Even get the soft line going up to frame as the jeep hard line screws right to it. Its just so simple. we help ya too.

I did the swap, but only because my rear axle finally gave up the ghost. The 35 will handle some moderate rough stuff, but the question is when it does die, will you still need to drive it out? Gonna suck if the wheel starts coming out on the way back.

If you take care of it and don't push it too hard, it will last you.

As far as the swap, I did it, by myself, in a weekend. And I'd never done axle work before. It's not hard, if you do your research and are moderately intelligent.

If the 8.8 dies in the same way - a C-clip or axle break - you're still not driving it out though.

always carry spares.

then of course there is the Superior upgrade that helps alleviate both of those.

While this is true........ how many guys running 8.8's have you seen like this?



I haven't, that's why I'm asking. I have seen this several times with the 35 though.

The hardest part is finding one for a good price. Everyone near me wanted $500-600 for one, luckily I pretty much stole one complete with lsd, disc breaks, and 4.10 gear ratio for $75.

While true (to a point) the 8.8 is considerably stronger than the 35 so it's less likely (than the D35) to break in the first place...
and if/when it DOES break - while not an ideal situation, it is possible to hobble it off the trail as the caliper (for short term) will keep the axle from coming out.

Maybe not up there where you at, but down here they are in mint shape and hold just fine. Now the ones jeep uses I dont like to reuse those. Seem cheaply made and of a crappy material.
Ones from Ford are well made and of a high quality material. The jeep threads gall a lot, but ford ones just dont.

I was told (from a wrecking yard two days ago) that the 4.10 geared 8.8's would only be in the two-door Explorers - does anyone know if this is true?

There is a local one tht they'll cut out from the vehicle for me for $250, but it has 3.73's, which just means that I'd have to spend good money re-gearing it.
