I got problems I've always had problems, but sence I got burnt on this jeep I bought 8 months ago I have serious problems. I've welded more metal into that thing than I think it origionaly came with!!! the boody mostly anyway my question.

I decided I better check the rear axle fluid and I thought it may have a locker or it was welded I popped the cover off and thnot a drop came out I'm fine with that because I checked EVERYTHING over and it's all fine but I may change the bearings and races but the rearend was welded to my regret and it's cracked I think I caught it in time cause it didn't blow apart and kill everything. but what can I do, can it be rewelded and how if possiable I really want to try and save it cause it's a dana 44 but I want the low down and aall the info I can get on welded diffs. the spider gears are no good so I want to try and save what I can. Sorry for the lenght of the question but please any info or comments would be more than a help it be a savuior.

Thanks

Welded diffs done right are fine. I've ran them and a lot of the people I wheel with run them. The best thing I have encountered is to weld the base of the spiders to the carrier, not the teeth. In the D44 on my J10 we added two extra spider gears for more strength.
If you don't want to replace the carrier, clean everything real good, and re-weld, or weld in new spider gears, clean real good again and fill it up.
Welded diffs are basically a spool, two tire traction, the tires will chirp on pavement, wear tires a little quicker, and are cheap, If they bust up a weld, the fragments can take out the rest of the internals.
Lockers give you two tire traction, lock/unlock on turns, cost more, if they break less ikely to take out the rest of the internals.

It happens once in a while, just heat it up and re-weld, we used to throw some extra metal in there,small pieces/nuts,bolts to make sure we had a good fill-in.

So to heat it up I can just use a oxyastoline torch? Just enough so that the weld penitrates, because the gears are harden steel so they would crack if heated too much because they'd lose their temper wouldn't they?

I use a salamander, but a torch or oven will work...450 deg Is what you want...the gears will handle 600 or more with out any problems at all...wrap the thing in insulation or something when your done, the slower it cools the better
