Hi there I'm stuck here I was trying DIY my rear end then as I'm taking out the bolt to take the pin out the bolts snaps and broke before it loosened so then I tried to pull it out with the extractor and then it broke inside any suggestions on how to fixe this problem

 

I assume you're talking about the shaft for the differential gears. I had the same problem on my Custom Cruiser. I ended up drilling/grinding into the end of the shaft until I hit the remains of the bolt, then unscrewed it from there. Of course I had to replace both the shaft and the bolt, but apparently this is such a common problem that my local Chevy dealer had the parts on the shelf.

 

Had the same thing happen to me this morning, snapped the bolt that holds the pin. So i Guess i will try and drill out the pin until i get past the bolt,, then hope i can back the broken bolt out, or is there a better way to
get the bolt and pin out.

 

I have always had good luck using a Cobalt drill bit when drilling hardened bolts... ( or metal) it seems the HF throwaways, or DIY bits dull to quickly and while they are dulling they are wandering, cobalts are brittle but extremely tough... they are available most places... just an fyi

 

Well A lot all depends on WHERE that little bolt breaks. Most of the time the pin breaks and it is clean before the threads-
IN this case hit the shaft area with a generous supply of brake cleaner and shot compressed air in the cross shaft area where the retaining bolt goes into the cross shaft and the round area in the case...SOMEtimes the little piece left in the hole will blow right out.

Retaining bolt with thread still on - The next thing you should try before getting all freaked out is NOT to mess up the threads- MOST of the time the retaining bolt wil have a ledge break and if you have a sharpe pick you can back the little bolt out by catching that ledge with the point pick end it is tedious and some times painful to have to go in and out little by little...I personally have had almost ALL of them come out this way.
AGAIN douse the area with brake cleaner so no oil is left behind. Then go to town use compressed air again in the round area while picking the bolt backing it out of the hole with the points pick. The air should make that pin float as you reverse it out. Light oil might help too after you get it clean.

I would say DRILLing is a last resort

IF you have a bolt in axle style you can bench all this work and tip the unit so gravity helps the retaining bolt come out easier with the pick method.

LAST resort if drilling does not work - HAMMER AND DRIFT-
4 pound short handle sledge hammer and almost the same size drift as the cross shaft. DRIVE the pin into the case do not drive the pin so it blows the retaining bolt out of the thin side of the carrier housing. USUALLY it will shear the hardened retaining bolt clean and then you good. MAy mess up the retaining hole a little BUT it will still be usable after removing the debris.

If the hole is blown all out of whack you can re-drill the other side of the carrier as the casting is the same on both sides.

GOOD LUCK to all of you DIY ers. Take care, Jim
