Mogs or Danas? (1 Viewer)

[cruiserrg]

Some dis-information in this thread. I'll clear up the error's where I have seen them...

Error: 404's have helical cut gears, and 406's have straight cut gears.
Truth: Early 406's also have helical cut gears. At some point (I don't know when) MB went to louder straight cut gears as the helical cuts put side loading on the portals and can cause them to break. For the record, if you have a rear steering axle, you need to swap the portals side to side so the helical gears are moving in the 'strong' direction when moving forward.

- Changing the offset/axle length of a 404 axle is a major hassle as the 404 axles are double tubed, and have not flanges/tube joints. With the flange on the 406/416 axles, tube lengths can be changed relatively easily. Exaxt did indeed move my front diff 9" to the right for a LHS offset for about CAD$600.

- the only thing that will break will be the portal itself, or maybe the gears. It seems the both happen at the same time, no one is quite sure which gives out first. The tips of the gears get sheared off around about the same time that the portal itself splits open. Mind you, this usually only happens in competition rock crawling situations with 400HP and a WOT at the other end of a long driveline full of gear reduction. Regular wheelin shmoe's like me shouldn't have much to worry about.

the bottom of my frame, t-case, and axles are all at about the same height... 22 inches of clearance. I vote for Mog axles.

Thanks for the post...

I wasn't aware there were older 406 models with heilical cut gear. Do you have a year or even vehicle code break?

Yes the 404's are double tubed, but most sellers of mog axles can do this for you (IIRC mine were $350 an axle to narrow the housings, plus the another $350 per custom inner axle...All done by Taradon). I have also read of guys narrowing their own, but I haven't done myself (yet).

There has also been breaking of the locker mechanisms (Dog clutch busting) in the 404 axles, which sometimes can take out the carrier and locker lever.

I agree the choise is mog axles. The thing everyone has to keep in mind is that there are going to be issues that need to be address with these. They are not a Bolt on deal to a cruiser. Mainly offset of the axles need addressing especially due to oil pan clearance and the front drivers offset of 3.5 inchs.

Sorry, I have no such information. Most of the parts I can afford have been from drum brake axles, which makes them pre 1971. I do have one single spare portal that has straigh cut gears, and I am pretty sure that it has drums too.

Nothing's impossible. Just a matter of time and/or money. My 406 axle changes from Exaxt were $200 for the tube, and $200 for each axle shaft for a total of CAD$600. I thought that was a bargain since I don't have the jigs to get it straight, a TIG welder, or the equipment to heat treat axles.

The dog on the 406's is about the same size, based on the picture's I've seen. Is it a matter of pure torque that is breaking these, or driver's pulling the locker on while under power and the shock loading on the dog gear.

There's always the unconventional... Depending on the mods to your cruiser, it may be easier to build new engine mounts and push the engine over to the passenger side, and go with a drivers side t-case like a ford 205.

I've edit my post with the rude inferences about the ih8mud forum. It was arrogant and unecessarily provocative, and for that I am sorry.

Peter Straub

It's all good. Just razzing you back a little.

Hey Peter I don't know if you know this truck, but he has managed to bend an axle housing. Don't know how (well pretty good idea) but he has it all messed up. He was breaking the same parts all the time, and finally realised his axle tube was bent. He's not called Carnage Kenny for nothin. The axles were from EXACT I believe.

I know that truck... The Hulk, isn' t it? In fact, Rob from Exaxt built it and wheeled in in TTC 2 years ago before it ended up in Carnage Kenny's hands. I heard that he broke the axle by jumping the truck.

Probably. I have never wheeled with him, I have heard about all his flops though. He is always looking for good sheet metal and tires, aside from axle parts. John Baron said that when Rob sold it to him he said he'd buy it back if he kept it in good shape...... now he wants nothing to do with it.
