I have been trying to ge this one bolt off all day!!!
I am trying to change the diff fluid on my 55 Cj5, so i need to take the cover off, all of the bolts have come off excpet for this one, just so you know the bolts have never come off since the factory and they are rusted in there, and they've been painted over!!
so far i've doused it in liquid wrench pounded it with a hammer, scraped away all the paint with a chisel, and almost rounded the head,
what can i do!! (remember im in the middle of nowhere in maine and whenever i need something for parts i either need to drive tow hours or pray that the builders supply has it)
ditto the PB blaster. wrap a string around the bolt and soak it in PB blaster and let it sit overnight. if that doesnt work, id go with heat. also, if theyre that tough coming out, id run a tap through the holes before you reinstall to clean em out so you dont snap a bolt on reinstall. (been there, done that)

Yeah definitely run a tap through the holes when reinstalling. It will take about 5 minutes and probably save you a huge headache down the road!! My aonly advice you be to give it a good smack with a punch in the center of the bolt then try to loosen it. (after the 3 - 4 gallons of PB Blaster!!)
well i bought the PB blaster and had them order a impact wrench at the builders supply, which will be there tommorow morning, so hopefully if i soak it tonight and then use the impact wrench tommorow then it will come out
and i definitly will re-tap then, thanks for the idea!!
I had one that would not come off my 88 diff, I drilled the head off the bolt. After the pressure was released, the threaded part came unscrewed using my fingers!!

Hmmm, So the diff cover had not been off ever in this jeeps lifetime? I'm hoping for the sake of your axle that at least someone sucked the fluid out and changed it a few hundred times over the last 50 years?
Also might not be a bad idea to use some brake cleaner and spray out all the holes real well before you put all the bolts back in. Also depending on the shape the bolts are in might not be a bad idea just to change them all out.

yup, you see it only has 27,000 on the odo. apparantly (*what the p.o told me), his dad bought it to use a round the farm (read for fun, [gentleman farmer, he was an insurance man, rich]) and then sometime in the 80s they ripped everything thing out that they dubbed uneeded and spray painted it green(so its an army jeep now;-) ), then his son took it and put in the garage and ran it once a yr in the 4th of july parade.
so if it sbeen changed it was only once, they guy didnt anyhting about motors and hadnt done anything to it since when he got it, but i got a really good deal, $400 "doesnt run" 10 minute clutch adjustment and it was running like a charm
anyway, i cleaned it out real good and there was no metal or anything in the oil so im good to go!
