Hate mog CV joints? - Pirate4x4.Com : 4x4 and Off-Road Forum

weps · 03-02-2008, 08:51 PM

Working in the shop, I came up with this idea. I HAVE NOT TESTED it under power yet, those results will be in 2 weeks. Meanwhile, this should allow for all of the "you can't do that" and "it will never work" comments to be brought up. This is a Dana 60 4340 Yoke,machined for full circle clips, pressed onto a modified portal stub. The hex dimension is still larger than the smallest stock mog shaft diameter.

Weps,
Just curious why we should "hate" the CVs, other than they are "odd"? I personally like the fact that there is less speed up/slow down compared to a u-joint, particularly at high angles. Are they considered weak? I'm not running a big motor, so maybe I'm removed from some of the issues being experienced.

Just curious...

Anyways, looks good.

yes, in regards to strength they appear to be a weak point.

Nice work weps! Excited to see how these work out. That is actually the same path I was thinking about going down.

U1300L · 03-03-2008, 08:55 AM

Go and get some U416 axles! Single joint in an Mog axle

unimog · 03-03-2008, 10:59 AM

Just get a whole Mog and be done. You can weld and Fab your other rig, and drive the Mog. They really work!

I posted this as others have reported breaking the "cross" piece in their stock
CV's, and were wanting something else.
The stock setup does work "ok", BUT I hate the .040 press fit on the pins,little rubber O ring dealio's and the fact that you cannot tighten the bolts that hold the thing together with anything other than a combination wrench tightening up the castle nuts

I shudder to think of replacing that (stock) thing on the trail, this is an idea to possibly simplify breakage, and cut down on the 10,000 moving parts the stock Cv has.

In regards to the "get a stock mog" comment, I am down to using the stock backing plates, gears, and 2 CV's.... The other stock stuff did'nt cut it. Great idea (portals) just not on par with what I'm wanting to do.

Greatlakeoffroad · 03-03-2008, 10:57 PM

lose the hand throttle Weps and your shit might hold it together a little longer!

So you got not the right Mog axles! Get another type of Mog axle and you will stop breaking them!

X-Rated · 03-06-2008, 12:14 PM

are these 404's?

The only thing I hate about mog cv's is they cost 1000 dollars... I wish someone would make a 1550 CV joint... Sean, cough cough, POS, cough cough

kabuki · 03-06-2008, 08:29 PM

they are 404's. Damn those U1300 joints are spendy! I'm assuming thats what you are refering to xrated.

OX · 03-07-2008, 05:07 AM

404's and 406's use the same CV?? (they look the same to me!)

Totaly different!

jptbay · 03-07-2008, 11:11 AM

I think what U1300L is trying to say is that there were several different style 404 CV's used over the years and some may be better than others.

It seems that the only thing he likes to post though is "WRONG!!!"

U1300L- It sounds like you are very knowledgable when it comes to unimogs. How about posting up some useful information on this topic. In your opinion what are the best axles and why?

Good, since I never hurt a 404 CV, should have no problem with 406 then.....

Knowledgeable ?? Possibly.
Annoying ?? Absolutely.

YELLOWHOBO · 03-22-2008, 09:53 PM

Any word on the testing of the U-joint? I like the idea.

No, sorry, I did not have time to put it in the rig for the badlands trip last week

I will probably put it in when I put the mog-9 in the front.

bigassjeep4u · 04-21-2008, 05:16 PM

I ran 404's in a buggy and had breakage issues as well from boxes to ring gear, kingpins, and cv. But this is def a good idea, even if it is just to make trail fix's much quicker. Although I believe if the pressed "hex" holds up they will be much stronger. Yes you could always go to a U1300 or cromo-Rockwell but this is about the 404 axle. Good luck

JR · 04-22-2008, 10:59 PM

I think the cv is one of the best parts about the mog.
In seven years I broke one... and that's because one of the bolts came loose.

I still can't believe everybody breaks so much shit on them, I guess I just drive like a pussy

We know you do wheel your stuff, and that it does not lack use or horsepower.
what "I" cannot figgure out is why your(mog)stuff does not break (often)

I been asked the question a lot of times and it's still the same answer.
Maintenance.
Girdle brace.
Red Line Shock Proof oil
Maintenance.
I check all the bolts on the portal box and cv joints after every run.
Recently, I safety wired the portal box bolts because they constantly came loose.

I have to admit that if a wheel is obviously wedged in a tight spot, I don't try to throttle out, but I've beat them hard over the years.

The weak point for me is the king pins. I've broke a couple (again, what happens is that they start to back out and then break)
I started tig welding the tops of the king pins to the lower knuckle, now I weld the king pin AND the slotted head king pin bolt right to the knuckle. It's going to be a bitch to replace, but it's the only thing I could think of to keep them together.

weps · 04-25-2008, 07:49 AM

Great info.Sounds like I need to move the safety wire(d) bolts up on the "to do" list. Those things really do like to come loose for whatever reason.

Hey JR can we get a pic of your wire job on your box bolts?
Thanks
