Through boltbroke in diff, fix

[blacksheep-1]

So I was going to build the limited slip unit in Superbeater, but when I tried to remove the through bolt thst hold the pin in place, it broke.
If this ever happens try fishing it out with a magnet first, in my case the center pin was galded , so what was left of the through bolt wasn't coming out. I went beast mode, using a punch and a hammer to try and force the pin out buy breaking the bolt off internally, but it was a no go.
I finally had to take the bull by the tail and face the situatio , I was able to sneak a grinder, with a cutoff wheel by the ring gear ( barely). I killed the carrier, but there was no way to get the center pin out to remove the axles.

That dreaded Murphy's law is always waiting in the wings to pounce when it can........At least you stayed nice and calm during the ordeal.......or then again maybe not..............

I feel your pain. One of the few bolts That seem to always be at best a 50/50 chance of breaking. I wonder if using the old flame wrench to give the case a bit of heat would help? The GM diff's used to have some nasty red paste thread locker on the replacement bolts, we would buff that off and use blue loctite.

Problem wit using flame is that the whole thing is saturated with oil, You can't get the center section out of the car at all, I felt it was just too risky, but it did cross my mind, along with a plasma cutter, but those fuel tanks are right there as well.

Yea, you took the right approach. It's one of those jobs that just sucks. The JC bolt.

no lie, on day 2 right now, going to day 3 tomorrow, the new carrier is a different dimension apparently
so I basically have to set up a diff, under the car, on my back, wrestling that b****, after, of course, the parts show up from Alpha Centauri or someplace.
