    I broke the spiders in the 12 bolt last night. I had to remove the pan, remove the gear teeth that broke, JBWeld the holes in the cover, fill it up with engine oil (all I had), and remove the rear driveshaft to get home. Now I have a front wheel drive blazer. When I was filling up at the gas station I noticed that I also have some negative camber in the rear???...So it lools like I bent the housing too (along with cracking the center section where the tubes go into it). I think I will be looking for a 14 bolt FF (because this axle is toast) out of a van to make it as wide as the front (I think I know where I could find a one). Than I think I will have the spiders converted into a "Lincon Locker". Now I have to find a 3/4 ton D44 or a D60 to match.

    When I broke the spiders it did not show up till after the hill climb that most likely took them out. I went about 1/4 mi and heard a funny noise. When I stoped someone said "your rear axle is leaking oil bad". I guess the ring gear had sent the pieces of the spiders into the cover to make the hole. The housing being all messed up just came from all the abuse I have given the truck over the past few months (I just got the truck in Feb.).

    When I bought my truck, the very next month I bought a locker and installed it. Then the ring &amp; pinion broke about 10 months later, and then again about another year later...
    It seems like with 35's I'm eating a Ring &amp; pinion a year on my 12 bolt- and thats beating it pretty good at Pismo 4 times a year.
    If I plan to keep the 12 bolt that much longer I'll invest in a TA Performance rearend girdle...Like Steve Chin has.
    Eventually I'll be swaping in a 14FF and Dana60.

    Damn Bro!!! sounds like you had a rough weekend. Serves you right for not inviting me to go wheeling...LOL. So where did you go? Think you'll have it done within 5 weeks? Or should I expect 2 passengers? If you don't find anything in your neck of the woods, I can always look in my local bone yards for the 14. Let me know, I have to go in the near future anyways.

    Sorry I didn't invite you it was kinda a spur of the moment thing. We went up to Cleghorn Rd. I broke it the second time up the hill with the elec. line tower on it. We went because my friend had just bought a 96 Toy and she wanted to wheel it.....well she put it on its side. I wish I could have seen it.
    This is my last week of school so I should have the time to do it. It would be cool if you kept a eye out for the axles for me. I am looking for a 14 FF from either a 1 ton or a Van and a 3/4 ton D44 or a D60 with 4.10-4.56 gears.

    I'll cruise over to the bone yards one day this week and see what I find. Why the 1 ton. Is that the proper perch width for yours? Do you have a measurement of the spring perches? Sometimes those trucks are so torn apart that you can't tell if it's a 1 ton or 3/4 ton unless you measure the width of the spring perches. And I'm sorry to say but if I find a D60 with 4:10's it's mine. I'll give you the D44 though.[​IMG] What gears do you have in it right now? And if you don't find a 44 to match the 14 are you still going to B-S? Or will you regear yours and upgrade it?

    Your axle housing might not be bent. With the spiders broken, there's no support for the side gears and they may have shifted in the carrier, allowing the negative camber.
