7018 is fine. I've used 6013 and nothing has fallen off yet. If I could weld better I would use 7018. hard for me to use since most my welding is laying under the jeep.

6013 / 7018 is what I use on most suspension and drive line work .

You could always run a pass with 6013 then cap it with 7018 but as long as your doing a good weld job I don't feel it matters too too much.

Cool Stick vs. MIG

Just go rent or buy a MIG. You get a much nicer weld. You get a hoter weld with stick, but it is very difficult to get a good weld on something that is rusted and even worse when it is still underneathe the damn Jeep. Just crank up the amperage and lay it in thick!

Use 1/8" 6011 rods on about 75 amps. They can weld on dirty/rusty metal, and are an all position rod. Be careful they can burn in deeper than the 7018 rods depending what you set the amps/heat to.
The 6011 rods spatter a lot, but they do give a very good weld and deep penetration into the metal. you can always grind the welds to look better. I have seen really "good looking" welds not hold. I don't always trust a MIG unless the metal is fairly clean. It just depends on what you are working with.

I use the 1/8" Lincoln brand from Lowes most of the time.

7018 rods make a nice bead, but you have to use more amps to get it to burn in as good and work much better on cleaner metal. I have a welding shop here at my house in the evenings as a 2nd job, and use a lot of different rods, but the 6011 is a really good all around welding rod.

Good luck
wherever you go there you are..........

Im a pipe welder by trade, and our standard is 6010 root pass for penetration, and a 7018 cap. 6010 and 6011 are good rods for penetration, but is much more brittle and apt to crack. If the weld you're making is taking any sort of torsional abuse, you should use 7018. In my honest opinion though, on an axle application, running a stick machine is too much heat anyways, and if youre not a seasoned welder, you can bend your axle tubes. I would use wire on good clean metal, and make sure you get good penetration. More is not always better.

I am retired Navy Welder. We wasn't allowed to use 6010 or 6011. 7018 or 11018 was what we used. The 6011 and 10 are to brittle like the other said and you can get a much cleaner weld with 7018. If you spend the time to clean the area you want to weld with a grinder before you weld you will get much better results. And is is always good to practice on something to make sure you have welder set up right. As far as 11018 we used on the hulls of Submarines and is a bit trickier to manipulate the weld bead. With 7018 as long as it is set up good and you have a good angle while laying the bead it will be just fine.
