rear axle questions...


Recommended Posts

i came across a guy today that will sell me his toyota 8" with 4.10s and welded spider gears for $250 or so...

but my question is should i get that or hold out for a d44 or ford 8.8?

If this is the V6 axle it has quite a following. It is very stout as well as about the profile of the D35. meaning you get a much stronger axle with out dragging you arse around!!

 

the down falls are the need to fiddle with metric brake lines/threads and the bolt pattern difference from front to rear after the install.

 

 

As it was said to me, Someone has to be the gunie pig...you might as well be him!!!

:-D :D

They're both good, just the more narrow one was replaced by one that was, I believe, 3" wider. The older one with larger tires and good flex would hit the tires on the frame. The strength is the same, unless it's a V-6, then it's even stronger. Both are good.

Yeah, I think I agree with Pete. It'd be a good swap, but $250's kind of alot. I got my whole Toy for $300; I'm sure you could find a wrecked, bad motor, or bad tranny, 2wd Toy for cheap or very close to free, and just pull it off there. Or spend the $250 and get an 8.8 off of an unknowing person.

I'd say depending:

 

 

You want to go moderatly big and replace the D30, then I'd get it and a matching waggy front. Waggy fronts are cheap to buy, but you'll have to regear them. But the width will be the same as that of the wider toy axle, at least I'm pretty sure it'll be almost bang on.

 

 

But if you're not looking to replace the D30, get an 8.8. They're nice and easy.

I will weigh in on this cause I am running the 8.8, and thught about running the toy axles, also almost did the waggy axle thing too.

 

 

The 8.8 straight out the box has 4.10's lsd, and disc brakes if you get it off a 96 or newer. The bad gear slection is limited. only up to 4.56 in the aftermarket, Ford has 4.88's available through the stealership. The Axle is almost an 1.5 inches narrower, and If you plan on flexing your rig, wheel spacers would be needed.

 

Toy axles. Cheap. Center sections drop out making swapping gears relatively easy. Disc brake kits are available. Gear and locker selection is also great.

 

Waggy axles. D44 has a huge amount of support. Can be found cheap in an old rusted out FSJ.

 

Forgot to mention the isuzu 44. Disc brakes, 4.56 gears, and did I mention easy to find.

 

 

Keep in mind all of the above axles are good up to about a 37" maybe a 38 if you run alloy shafts. Much bigger then that and you have to go with D60's or bigger :twisted:

 

 

Swapping the rear axle can be accomplished with minimal amount of tools and moderate wrenching experience. Front axle swap is a lil more difficult and will require moderate to severe experience especially if you plan on welding on all your own brakets.

 

Now for the disclaimer These are my opinions, and not neccesarily those of fellow board members.

Personnally I don't consider the waggy front end to be all that much better than a Dana 30 with 297 joints. It's plenty of work to swap one in just to get the same joints and a low pinon. And I wouldn't think too hard about the Toy rear unless I was swapping the front to match the rim pattern. Even if the axle was totally free I'd just resell it to help pay for a better axle. I found a junkyard kinda-near me selling Ford 8.8s for $100.

Jeep on!

The problem with trying to sell a D35 is everybody is upgrading to something better. with everything you listed, you probrably would get more if you put it on ebay and was to sell just the gears and lockers, then sell the shafts and brake parts in another auction. Problem is the MJ rear only fits MJ's. XJ/YJ/TJ/ZJ owners would all have to make new mounting points.

You are going to have to relocate your spring perches. On the XJ they are wider apart. YOu can go buy new paerches from Advance auto parts through their Mr. Gasket catalog, or you can make you own out of tubing.

 

The only axles that swap directly in the rear of a MJ is an axle out of another MJ. The front axles, from the TJ,ZJ,xj all bolt right in.

 

I am glad that we pointed this out to you before you went and tried this.
