Ive been reading that if u put one piece axles in a model 20 rear that u should weld the tubes.I have no problems with welding the tubes.My quesions are (1)if i dont they will break right?.(2)can i weld them without taking my rear apart?.(3)should the truss be on top or bottom?Just for info im runnin a 304 and plan to install 4.10 gears in the rear so i will probably take it apart anyway.I have moser one piece axles in the rear.One more question i am going to put 35 inch tires on her and ive been reading that 32 and 33 inch tires are the majority for rock crawling.I have a 4 inch suspention lift on her will i have tire rub?I dont mind a body lift if i need one.kenny
I am not so sure that you HAVE to weld your axle tubes. I say this because I too have the AMC 20 rearend and have run Moser one piece axles for over two years without any breakage - also have a LockRite locker. A buddy of mine has the same set-up and has had his for four years or more - no weld and no breakage. I dont think welding is a bad idea and would certainly only be a benefit. Just thought I would share my experience without welds - take it for what it is worth.
As far as the tire size - I have the RE 4.5 lift on mine with 33's and have plenty of room for 35's. My only caution is depending on what kind of lift you have you may be able to put 35's on now but in a year or so you will have sag and your 35's may rub at that point. Suggest you do the re-gear before running 35's however - many folks complain after going with 35's without correct gearing.

I very much envy you. Spent three weeks in CO Springs, I though I would be moving there, but I took a different job. The 4x4 shops out there blow away the places in the Northeast, even though there are a couple of really good ones here.
Hope to drive my CJ out there one day for about a month of wheeling in CO, Utah, etc.

If I remember correctly, they told me in my welding class to be careful of welding when you have bearings. But, if you put your ground clamp between the weld and the bearings you should be ok. Personally, though, you really don't need to weld the axle tubes in the first place... several people use the 1piece axles with that mod. If you do it, throw in those 4.10 gears at the same time.
