I've only done it once. So far so good. I used 7018. Welded the spiders together and then weled them to the case. I made quite a few passes too, I wanted to be sure I had enough weld in there.

If you had your choice, would you use MIG or stick? I have both, I was thinking that the MIG would be better, no slag to chip out and chew up the bearings.

My buddy tug78 is on here occasionally I welded his spiders in the rear of his toy and I used my Miller 185. No problems so far I welded the spiders to the case and vise versa letting it cool and not get to hot.

I welded mine with a Mig, just pretty much turned it up on high and melted the gears together. Working good so far except it sucks to drive it on the street. I would definately use the Mig - less spatter

I used 7018 and filled a couple of tooth spaces. Make sure it's nice and clean (I used brake and carb cleaner spray), then go to town. <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0"> <IMG SRC="smilies/biggrin.gif" border="0"> I don't agree that it sucks on the street, it's a lot more predictable than the EZ locker I had before.

The welder who did mine pre-heated the gears with his oxy-acet torch set for a big ball. Then he used his MIG. Let it cool slowly.

I haven't had any problems. In fact, last winter I broke a bunch of teeth off the ring and pinion, but the welds held fine. Took another diff to the same guy and had him do it again.

It's not too bad on the street, very predictable. Just have to turn the steering wheel a little further than before <IMG SRC="smilies/biggrin.gif" border="0">

Only if your mig has enough amprage. I wouldn't do it with a 110v mig even with flux core but that's just my thoughts. The only drawback of arc is chipping the slag between passes and when finished. A little time consuming but not to bad. I've got a pretty good pic of mine but I have no way of posting it. I can send it to you if you want to see it.

my roomate had his come unwelded a few weeks ago, I welded that with a 200 amp miller MIG on setting 5 of 6. Dunno what the deal is, it just "unlocked", no noise or bang, still drives fine.

Suprised the hell out of me, I welded the crap out of it, at least I thought. I'll be going after it with the stick welder and some 7018 when he pulls it back out.

maybe I'm not doing this right?

scottz..... you need to weld more than just the one edge...... you should also weld the other two spider gears to the carrier. I had to remove my ring gear to do it right.....

it'll work better if you weld the gears together and not the gears to the carrier. when welding the gears together you are welding like metals where the gears to the carrier is unlike. weld the gears together everywhere you can do more than one pass. also make sure everything is completely clean and when done make sure and get all the slag out. clean it really well. i also suggues taking the ring gear off or atleast cover it to ensure no dingle berrys find thier way onto the gear.
