Okay, I was installing my new ring gear tonight when one of the bolts broke! I was tightening them in a crossing pattern, first at 20 ft-lbs, then 50, then 80 to finish and... SNAP! Now what? Do I have to start over with new bolts? The FSM says 70-90 ft-lbs.
When a bolt is tightened into its yield zone it needs to be replaced if removed. Anything with a torque+ degree is always that way. Some with a simple torque number are too. Anything thats load/torque bearing i always replace.
i would drill it out and replace it with hardened bolts. or whatever tickles your fancy. when i bought my gladiator, the previous owner replaced the ring and pinion and broke a couple bolts and left it like that. come to find out, after going thru the diff, it was trashed (maybe because of this, but who knows why) i mean there were chunks missing in the pinion, the casing had a crack in it the spider gears were all screwed up and the cover had dings in it from the inside from the ring hitting it (why i dont know) but if i were you i'd play it safe
