why does a 404 mog have + camber in the front? I have seen this in a few pics and on my front 404 axle before and after i cut it apart to move the diff over. is it built into the knuckles? are they adjustable? wtf????? its only a degree or so out of plumb but it would make tires wear funny and reduce traction especially in a hard corner.

you might be able to see it in these pics......and yes i used and alignment bar when i butchered my axle

oops here are the pics. you can see it in mine (the first one) and in these others i found online.

i noticed this before i cut the axle apart so when i cut mine apart, i used an alignment bar to tack up the ends and gave them a degree of neg. camber to get the tire to sit square on the road surface. i put the outers back on to check everything and couldn't rotate the tire when it was all bolted together. when i set the camber back to stock it was all good. help???

I belive it was for the weight. It does not wear tires offraod on my buggy. I also run 12* back on the front to help in the go fast steering.

wow 12degrees of caster? thats a lot! most rigs with normal axles use 3-5. but if your getting away with that much it could help

I always heard that it was for the weight capacity of the original
truck.

I started a thread about this a while ago: http://www.pirate4x4.com/forum/showthread.php?t=293010&highlight=wrong+mogs
It has worn my tires a little funny and it definitely doesnt help with cornering. After a couple years of having to look at it and now that Ive got my axle torn down for my king pin fix and disc brake conversion I decided I was going to fix the \--o-/ camber. It gets pretty noticeable with 47" tires. Im getting the outer knuckle milled where it attaches to the backing plate. It looks like there is enough material and my Weps steering arms have that horseshoe shape that sandwiches it all together for strength. The flanges at the axle tube end are square, its the outer knuckle thats got the camber built in it.

My outer knuckles are at a buddies machine shop and he hasnt run them through the mill yet so if you wanted to get yours in too it would keep the cost down since they would already be setup to do it. Just thought Id throw that out there, PM if your interested.

since im gunna have to bust some hard tacks off the axle ends to make a caster adjustment, i might try to cheat it out of there, like weld it up and bolt it together and let the end bushing self clearence......but if not id like to find out more on this machining, Aaronius. this camber this isnt gunna "fly" with me:D

PM'd you back montanatrout. I agree the \--o-/ gets hard to look at after awhile. Reminds me of a knock-kneed axle.

Here's a pic (not my axle) and the red line is a rough outline of what would be milled. If I remember right Im having 2.5mm (.098") just over 3/32" taken off. This seemed to be the best place to "fix" it at. Theoretically, I dont think there will be a loss of strength since the steering arms sandwich the back plate and all the steering load is transferred through them to the backing plate.

I looked into shims at the axle flange but that didnt pan out. And when you start messing with the flange at the axle it starts messing with seals, bushings, bolt holes, dowel pins...forget about it. The only other thing is custom knuckles...:smokin: I almost attempted it.
