Welding axle tubes?
I am wanting to weld my axle tubes to the housing on a 8.8 rear end. I am looking for some advice on the RIGHT way to go about this. I am worried about the the fact that the housing is cast and the axle tubes are steel. I do not want to ruin this rear end. I have access to a stick, MIG ,or TIG welders. I need to know which would be the best to use and the type of rod to use. If there are any experts out there on welding I would really appreciate any help with this. You can email me because I still have a lot of questions to ask. My email address is: jdllambr at bellsouth.net.
Thanks,
JD

Welding axle tubes?
Why do you want to weld your axle tubes....if its for strength your not going to find much there. Your axle tubes are press fit into the housing, the spot welds that are there from the factory are only to keep the tubes from working their way back out. They do more than enough holding to do that. by welding around the tubes to the housing your actually going to weaken the housing, therefor counteracting what you really wanted to do. If your looking for more strength from the housing i'd try some other routes first...a axle truss, a stud girdle cover, and some stronger axle shafts...If those don't satisfy you for strength...go to a bigger axle for more. Good luck and feel free to email me for more info...i love axles....

Welding axle tubes?
Ryan is probably right about it being a bad idea to weld your axle tubes to your housing. But in response to your basic question, I've had no problem welding steel to cast iron. When I put a 1 ton GM axle in my F250 I had to weld one of my new shock mounts partially onto to the housing as well as the tube. I used a MIG welder and had no problem welding 3/8 inch mild steel to the cast iron housing. It's plenty strong, I frequently jack up the rear of my truck by that shock mount.
