Please, if you don't feel comfortable welding this DON'T! Serious death or injury may occur! ← That is my disclaimer...

Oh COME ON, let Darwin do his thing....we need to reduce the # of dumbasses in this world.....:D
 
No, it is not high pressure pipe, but it is still a critical weld in my opinion. AWS standards are for all types of critical welds, not just high pressure ones. The reason they have standards is because they are proven to make good welds all the time. It would only take 30 minutes to make the joint design to AWS standards. 30 minutes is not much trouble in my opinion and it is well worth it. Why guess when it comes to safety? I don't mean to keep harping on this, but safety is the type of thing that they stress in welding school. If you go to welding school they teach you about critical welds, who should make them and how to make them.

Confidence is not a substitute for competence.

Pin_Head I will admit that I should have and certainly could have spent more time prepping the area for the best weld and procedure I could achieve in field conditions.
He is correct guys this is a critical weld and needs to be taken seriously. However, lets not turn this into a "how to make proper weld thread" that was never the intent of this thread nor did I assume that everyone would be running out with their 130A welders trying to weld the knuckles back on. Please use the proper machine and procedure to weld the knuckles back on.

True, but 80's are getting hard to find and we don't need to be destroying them because knuckles are falling off! ;p
 
I see this as a great option for the 37 and up crowd. Control arms flipped on top, cut and turn, high steer, and 40's with good road manors...who da ever thought. Saved for another thread:D

Pretty much what I posted in another thread BUT...

control arm flips are for guys without the grey matter to design a proper radius arm for a given lift!

:cheers:

Haha, yeah right. If I designed a radius arm, it would be for a flipped possition. But the factory arms work. So why bother?

Control arms that correct caster, address driveline angle, re-center axle in the wheel well, and afford any less rigidity to the fronts ability to articulate ARE "the more elegant solution"....but must be crafted out of unobtanium.

Amen brother.

Why not a 3 or triangulated 4 link

edit: sorry, dragging this way off topic
 
I believe it ended up only being 3/16" or 4.7625 mm for the rest of the world. :flipoff2:

I think i heard 5/16 on a inch was was needed on a 60 axle, but that was a few years back when i heard that. i maybe completely wrong but for some reason i do remember that.

cheers and love the write up, super easy to follow, great pics and a NO BS outcome

cheers
 
I got to drive this truck a couple of weeks ago. Just on pavement but also up to speed, ie 60mph. It drove unbelievable! It felt like a brand new truck, the steering the handling, the brakes all felt incredible. I had driven the truck before although off-road on snow and it sure felt like a completely different truck to me two weeks ago. The steering and braking being the biggest improvements I noticed. Both being very responsive and very sweet.

Thanks Bro!
Just an update, almost 3 months and a ton of miles including a week long trip to Colorado (1500+ miles) and not a single problem! Like ↑ said it drives amazing...
 
They dont drive anywhere near as good. Tried them all. But happy to jump in other trucks running these set ups to compare.

Word. But they don't flex like a proper linked setup, either. Depends what you're doing with the rig, I suppose.
 
Waiting until I can do a cut and weld on mine.. -1 caster sucks

but those welds are pretty critical

my friend had his knuckle break of on the middle of Europes biggest Glacier..
luckily he wasn't going very fast and the snow dampened the blow, broke the axle tough but everything else was good, steering, break lines, everything except the axle broke inside, we had welding pins delivered to us from another group nearby , actually had to meet them in a hut 25-30miles away spend the night there and drive to the truck the day after early morning , weld it together, then he only had 3 wheel drive and we had to drive over the glacier to get down the other side, got gaught in a blizzard with winds up to 30-40m/s took us 20 hours to get of the glacier :) but we made it , barely :) my truck with only 2 wheel studs on one front wheel, got loose without me noticing

But yes... those welds are pretty critical, and have been reinforced on both sides and shouldn't break again.. but what do you know with 46" tires :)

That looks really, really, cold......:eek:
 
It was really really cold :) you have to wear suitable clothes for wheeling like that , the weather was actually not that bad when we welded this , later that day/night we were caught in a blizzard, -22° celcius on my temperature guage and the wind was blowing 30-35m/s so with windchill the cold was probably -30 or more , my LC80 was running fine in that cold, but shaking and I had to constantly go out open the hood and clean the snow around the injector pump, because the accelerator linkage got covered in snow and the engine ran @ around 1500rpm unless I regularly went out and cleaned the snow away, when the weather was at its worst we were making maybe 1km in 1 hour , 7 trucks driving in a row, me in the lead driving by GPS tracks with zero visibility outside , It was quite an adventure... but its definatly not for everyone :)

pretty much the visibility we had.. the windshield wipers froze.. and were of no use :) also at times the insides of the windows froze up
