AMC 20 weld tubes to diff housing?

I have a built AMC 360 that is pretty stout. I recently spun an axle shaft in the hub of my stock 2 piece axles while on the street. I do mostly street driving, occasional trail riding and some more rough 4 wheeling. I have ordered a set of moser 1 piece axles and have yet to install them. I have read that sometimes you can spin the axle tubes in the housing with too much power, but i don't see how that could possibly happen ( maybe someone could explain). So how can I make them stronger or do I even need to?

Also, I know about trusses and really don't want to go there as I don't do hardcore wheeling that would bend the whole housing.

Oh yea, if it matters I have the QT with MM PT and 33's.

Spun the hubs and spun the axle tubes in the chunk on my 84. I got lucky and it pulled back into place and is now welded and is sporting superior 1 piece axles. All this while running 31x 10.50 BFG AT's with a little stock 258 I6.

WELD IT. If you are not offroading much you may be alright with out trusses. If you hardcore trail ride I would add the truss. I have not but really need to now that I am running 33's and lockers and tend to get wadded up in rock piles quite a bit.

Ok, welding sounds good. Since i am not a welder nor do i have a welder, what would be the easiest way to have this done. Does the axle need to be taken down to the bare housing- because that is not an option. Could 4wd (the business) do this?

Me and a buddy of mine welded mine. I suck at welding and he is a novice. It is not hard to do and any decent welder should be able to do it. Weld a little and let it cool a while on its on. DO NOT QUINCH. Keep heat to a min. It does not take a lot. A 4WD shop should know how but a certified welder would be best since you are weldig mild steel tube to cast. There are holes in the cast near the end we welded inside the hole to the tube and a few tacks around the end of the cast for for good measure. If you you take your time and weld a little on one side and then a little on the other the bearings should be fine. I put a floor jack under the chunck and put just a little upward pressure on it to make sure it did not sag in the middle.

Good luck.
