how strong are unimog axles? will they stand up to a torque built 351W and C4 auto? anybody ever break one? how much do they cost to get narrowed?

thanks in advance

They withstand easily an 500ci cady with th400 39.5 boggers !
Because my CJ5 was equipet so never ever broke one !
You only break those axles when somethinhg is lose or there is no oil in !
Belive me !

Hey Danny what happened to you saying you " want" some of these axles over on the SRC board??

Yea, they are like diamonds and platinum if you have them and are trying to sell them.

Yes they are breakable, has happened in several rockcrawling competitions here, and has been happening for a long time in Finnish offroad trials. To see Finnish offroad trials go here http://www.teli.stadia.fi/~jjsalone/Home.htm , awesome site!

There are things about Mog axles that make them not for everyone. You can see all of my thoughts on Mog axles over in the http://www.sierrarockcrawlers.com bulletin board. There have been quite a few discussions regarding Mog axles over there.

But to save you some time a will without going into detail name some of the reasons that Mog axles are not for everyone/unbreakable.

The Portal gearboxes on 404 axles -depending on use- may not last behind your engine.

Also the stub shaft after the gear reduction has been known to break even on light weight buggys with ~150hp and shock loads(such as bouncing around on rocks with the pedal to the floor).

They are very hard to make fit in a standard configuration(american type) vehicle. with the front diff being offset to driver side 3.5", and rear diff offest to the passenger 3.5" (the engine is offset 3.5" to the passenger side on mogs)

The only have one gear ratio available at 7.56:1 ratio.

They require custom adaptors for the driveshafts, and custom steering arms if you plan to use any type of standard steering box configuration.

They are defiantly sweet axles, just not for everybody as I have said before. Many of the breakage problems that happen with 404's is not really a problem with later axles like those from a 406/416.

If still interested in Mog axles, and want to know more about their weaknesses/strengths, and the differences between 404 and the later Mog axles go check out some of the discussions over at SRC. Here are some links to some of our discussions from over there.

If you have any more questions regarding this matter, post over there, as I hang over there more often.

i think the main weakness is the portal housing as i have seen them explode under hard use.

i have a steering mog axle that i was gonna build and after taking it apart and looking at the pieces decided to go with custom 60's.

Camo, you should check out the portal hub from a 416. BEEFY! I would say that as far as engine torque through them that they are nearly as strong as a Rockwell 5 ton axle(though not quite as strong as a load bearing member as a 5 ton axle, 416 trucks are rated 4 ton load capacity). The portal housing itself is much stronger than 404, and everything inside is much stronger than 404. The stub shaft after the gearing on a 416 is a bit greater than 2.5" diameter, and is 35 spline(416's are 35 spline throughout).

Anyone have a link or idea how to flip the front so you have 2 PS drops?

I have not looked into the flipping possiblity yet. But remember even if you do get it to work, you will only have both differentials offset 3.5". The inner knuckles on steering axles are removeable on Mogs so it may be very easy to make this work. Flip the housing, leaving the 3rd member straight up, flip the knuckles, and bolt the hubs back on.

It might work.

i have never seen any of the newer mog stuff around here but i will keep my eye out for some.

how much $ are people getting for the 416 steering axle?

Why wont it let me see your page?
It says that I do not have the latest version of explorer(although I do). Says go update my explorer(I just did) and I still get the error.

Says I have version HTTP/1.0 and need version HTTP/1.1??

I have seen a 416 and inside it's reduction case. It looked a little different but no beefier than a 404. It's a tiny farm vehicle.
I thought a 406 was the same as a 404 only it has disk brakes.
I heard that Dan's "rock mog'' broke a portal case ( ok, I saw it on vidio, it looked extremly punishing).When I asked about it I was told it broke do to side impact.
Hearing this I had 1'' straps welded around my reduction boxes.
And yes, I've heard that the spindles break. Probably because the spindle bolt is not tight (400 whatever lbs.)
I've flogged the shit from my portals (knock on wood) and they have not broke yet.
Some people can bend a crow bar in a sand box :smokin:

You guys seem to talking about only one or two different Mog Axles. The 404 axles are popular I guess because they are cheap, relatively speaking. They were designed in the 1950's to be fit to an 84 HP engine. The 416 is a newer diesel truck that was introduced in the early 70s with a 135 HP diesel engine.

You want modern axles, like the ones off a U1300 or a U1700. I dare you to break one of those on a Jeep, but you better bring your Visa card AND your AmEx, because those bad boys are probably gonna cost more than your rig!

Unipaser should be able to get you a price on those axles. Maybe a few other places as well. But for far less money, a Dana 60 or similar should get it done for you guys. And they are a LOT easier to find parts for.

Good luck,

Did some checking around,

Frank Atkinson Mogs in England is always a good source for modern spares. He has some of the high speed U900/U1100 axles for £1500 or about $2100 for exchanges. I'd bet on $3k for new. The U900/U1100 is the smallest of the modern trucks. The U1300/U1500 are the medium trucks and the U1700/U1900 are the big boys. The U2450 is the 6wd version.

I'd suspect a 100% price jump between each class of truck for the axles but a corrosponding increase in strength. Go here for more:

Well, they outta know how tuff they are...It says right on thier site...
"We are the Biggest European Unimog Breaker"

I don't know if I'd want to buy anything "Used" from these guys !


I know, I know...The Brits name everything wrong...
A "hood" is the top and the "Bonnet" is the hood, and a breaker is a scrapper.

Ummm U1300 axles are almost exactly the same axles that are in 416's as far as this conversation is concerned. Portal housing/gear strengeth, differential strength are all the same between them. Pretty much the only difference between them is they used a different type of spline for the axle shafts. They went from splined shafts to keyed shafts. The difference is that instead of having splines on the shafts, the axles had flanges on the ends that mated to an identical flage at the portal housing(Like two interlocking discs).

And how in the heck can you tell me what is going to get it done for me? An almost stock Land/Range Rover doesnt get it done for all of us.

Station,
those finnish guys are using Volvo lapplander axles !
Those axles are looking like UNIMOG axles but they are smaller !
I have never seen an 35 spline UNIMOG axle shaft ,not in an 406 416 1300 etc.

No.
No.
Wrong.
You havn't seen 35 spline shafts, but you have see 3" dia. stub shafts on 404 axles. hhmmmm.

We already went over this on SRC (sierrarockcrawlers.com/http://www.sierrarockcrawlers.com/yabbse/index.php?board=1;action=display;threadid=848;star t=15)

I've seen enough Mog axles break to change my mind on possibly running them.

There was a mog at the ProRock event this weekend, and he blew just about everything up.

That is why I am buying 416 axles. They are quite a bit heavier, but waaay heavy duty. Like I said above. I would say that they are nearly as strong(as far as torque run through them) as 5 ton Rockwells. I have seen them anywhare from $2000 a set to $6000 a set depending on condition and who is selling them.

What all did the guy in the competition break?
