As most of you already know, I welded the front and rear spiders of the S-10 and the front exploded April 7th. Not like everyone didn't tell me it was gonna happen, but I welded it anyways ;D. I mean common, I even had a way to unlock one front wheel from inside the cab so I could turn easily. Anyways, I finally tore it apart today to see what the hell happened. I assumed the weld didn't hold considering when I looked under the truck after it went "kaboom" the housing was in two pieces. Well it wasn't the weld, the stub shaft on the passenger side snapped in two and just happened to take the small side of the two piece housing with it. The carrier, welded spiders, ring and pinion are all still intact accept for one little piece of one tooth on the ring gear. I'll put another front diff out of a parts truck in it to get me going for now but this may not be the end of the welded front diff ;D ;D ;D. I took some pics of the mess incase anyone wanted to have a look. Here's the link... www.cardomain.com/ride/2627072 |

u better get a bigger truck That way you can break your front axle in 10 minutes instead of taking 2 hours to do it.  |

what size tires you running when you blew the stub ? I only run 31's. There really agressive...but still only 31's u better get a bigger truck That way you can break your front axle in 10 minutes instead of taking 2 hours to do it. You took the words right out of my mouth ;D So I took the replacement front diff apart last night to check it before I install it (I have other front diff parts lying around from others that were taken apart also) and wanted to dig up some less worn thrust washers for it. Anyways, make a long story short..er....I noticed there are two different size stub shafts and are inter-changeable. Also, the stub that broke was the small one. So now I'm kinda wondering will the bigger stub stay intact if I repair the welded diff? does a sixteenth of an inch or so make that much difference in strength? Here's a pic of the two stubs, all feedback and criticism welcome  i175.photobucket.com/albums/w142/CharlieD07/IMG_0990.jpg |

I'm not sure about S10 axles but I can tell you the differance between differant sizes of D60 axles.
Standard Dana axles (1040 steel, induction hardened)
30 sp 1.31" 6,044.1 ft/lbs
35 sp 1.50" 8,966.2 ft/lbs.
Moser Engineering (1541m, induction hardened)
30 Spline - 6,200 ft/ lbs.
35 spline - 9,600 ft/lbs.
Aftermarket 4340 steel, thru hardened
30sp 1.31" 9,923.5 ft/lbs
35 sp 1.5" 14,721 ft/lbs
The Formula ,if you want to measure up the differance between your 2 axles and calculate it for yourself, is:
Yield Torque (in/lb)= Tensile Strength ( psi) x polar moment of inertia/ radius of material

Bigger stub may stay intact but it'll probably just find the next weakest link but then again it might hold up pretty good , just keep it in the back of your mind and keep gathering up spare parts

Well I got the front end back together tonight. She's just single trac for now. The front end I put in didn't look too too bad, but did look like it had alot of miles on it. I guess we'll see at the next run if it stays together or not lol. I have a parts truck with 4:11's under it. I think I might gear them up and fire them in.
