I picked up an inexpensive 404 mog the other day (primarily for the axles). Engine is seized and missing a bunch of stuff. Anyway KC and I are planning to install the axles in my Defender 110 pickup. Problem is that the diff drop on the front axle is on the wrong side. Anyone have some tips on cutting and flipping the diff to the other side? Webpages? Thoughts? I know it has been done already so someone out there knows.

Thanks for the help,

Billster

ps. BTW, still planning on putting the 404 back together again when we get some more cheap axles.

Yes this is my question too....its good to hear that its been done. My app is the u1300. I ruled this option out cuz i thought there was no way to keep it from spinning backwards if you did this.

heh.. I'm so glad that KC pointed out the other day that i can just unbolt the tubes from the diff. and swap em to the other side, on my 406's. then just swap the portal boxes back to the correct side. :p

big sub you should be able to do the same with your u1300's ;)

who told this to you......... you cant flip tubes to other side......

tubes have the bearing for the diff and other side has bigger bearing and there is the locker inthe other tube too..........disapointed :flipoff2:

hmmmm.. that sucks. we were just assuming that it could be done if we re-splined the one shaft for the locker. sucks about the bearing change. :(

my shafts are necked down just after the splines, you cant even re-spline them :( :(

WHY,WHY,WHY!!!!! If it was american they would have used all the same parts! So does this mean there will be no diff flipping?

Please post a reply if you know lots about mogs and have NEVER seen a diff flipped.

Definitely post if you HAVE ever seen a Mog diff flipped. Thanks

big sub.
I dont thing franken is talking so much about actually "flipping the diffs" upside down, but more, flipping them from drivers side drop to a passenger side drop.

with a "flip" of this nature all that is required is re-tubeing of the housings.

and nothing is going to spin backwards.

Sorry. I'm just a dumb newbie. Thats all i want is a pass side drop. But what you just said and what zag said:who told this to you......... you cant flip tubes to other side......tubes have the bearing for the diff and other side has bigger bearing and there is the locker inthe other tube too..........disapointed

Seem to contradict. Or am i showing my newbieness off again?

I have a pass side diff on my Mog 404 front axle, but I had Exaxt build it. It's not cheap, but I already had the Atlas and I had better d-line clearance on the Pass side too.

Whats "not cheap". Did you already have the axle or get it turnkey?

I was seriously planning a rear mounted motor for my buggy as well using these axles to accomplish this.

The way I was planning on doing it was just rotating the center 180*. This would still flip the diff.

But the problem is with the centre the bolts wouldn't line up. I had to rethink a few things like putting the motor in the front.


Here is an example of what I was refering too.

but why not use ford or some other rigs driver side drop x-case.so you dont need to change anything from axels.....it keeps the parts stock and cost down.

ill bet you have tons of ford np205 cases over there :smokin:

and SAPPER could just cut the inner c parts of an rotate the axel upsidedown........like you change your caster in other axels :idea: :bounce:

Cuz the cummins 8.3 liter i want already has a big ass tcase with pass side drop.

I already have a Chevy203 mated to a ford 205 for the driveline angles but I wanted a rear motor without using a v-drive to accomplish this. Ie like the people running Ford 9" flipped third members and having a centred front pinion and an offset rear. I would be then driving mostly on the (normally front) output as well. I decided to just stay with the standard axles but hopefully with the help of a machinist and a CNC machine convert my expensive drum parts and hubs to accept cheaper disks and calipers instead of the hassles of trying to find brake parts later.

Yes this is my question too....its good to hear that its been done. My app is the u1300. I ruled this option out cuz i thought there was no way to keep it from spinning backwards if you did this.

We've done quite a few 404 housing flips now (and kept the double wall).
We've also done 406 series axle flips too, so yes it can be done.

Are you able to keep the locker? As I'd researched, I had seen that it has been, and can be done, but you are SOL on the locker if you do it. Is this wrong? Or what is the solution?

The solution is a custom shaft.

Correct, a custom shaft is a solution. We can provide people on a budget with another option, though...

What is the other option???

I am looking into this too, I am considering some 421 portals (narrower than a 404 (which I need) but supposedly about as strong). Only problem is like Frankenrover I need to change the front to RHS drop.

We made the diff flipp for the 404 type axle. Just cut the axle, weld it back together and make custom shafts, easy and simple as that :D :D

And ffriend with the U-type axles made the same thing. Ya know it's just iron you need :p

Well yes I know that custom shafts costs more, but in our case it was not even so expensive and that was the only option to do it for our Alfaster.
