JeeppinTom Posted June 20, 2006 Share Posted June 20, 2006 Soak them with some PB Blaster. There is some better penetrents out there, just can not remember their name. Also smack the bolt heads with a hammer or with a center punch. Don't damage the edges. Link to comment Share on other sites More sharing options...
rejeep Posted June 20, 2006 Author Share Posted June 20, 2006 these are the bolts facing the yoke... no room to hit... but i did start soaking tonight. Link to comment Share on other sites More sharing options...
sinnaevd Posted June 20, 2006 Share Posted June 20, 2006 can you heat and cool? i've heated them up and then sprayed them with a hose to cool it quicikly, and then usually breaks them loose Link to comment Share on other sites More sharing options...
jeepthing07 Posted June 20, 2006 Share Posted June 20, 2006 I had to weld nuts ontop the bolt heads on a 1997 XJ after i rounded them off Link to comment Share on other sites More sharing options...
hemi_comanche Posted June 20, 2006 Share Posted June 20, 2006 heat is your friend trust me I had the same problem and I just used a mini breaker bar from craftman with the shortest socket that was the right size and put it on and got it in position, and went at it with the torch for about 20-30 seconds, then gave the handle some hits and that broke them loose and it was easy after that. Heat is a wonderfull thing. ;) Link to comment Share on other sites More sharing options...
JeeppinTom Posted June 20, 2006 Share Posted June 20, 2006 Use a 6 point socket also. 12's are famous for round bolt heads. Link to comment Share on other sites More sharing options...
mjeff87 Posted June 20, 2006 Share Posted June 20, 2006 Use a 6 point socket also. 12's are famous for round bolt heads. X2 on that...I ruined many bolt heads before I realized it. I've only got one 12 pt socket that I use, and that's 13mm, for the 3 hub bolts. Everything else is 6 pt. Jeff Link to comment Share on other sites More sharing options...
Oizarod115 Posted June 21, 2006 Share Posted June 21, 2006 mjeff... how in the WORLD do you get those stupid hub bolts off!!!! theyre torqued like crazy, and the one behind the center cap too... how?! Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 21, 2006 Share Posted June 21, 2006 Heat em till they glow, put a 12 point combination wrench over them, hit the wrench with a sledge hammer. If you're using quality tools that actually fit right, you won't round it. Wailing on the wrench with a sledge gives it a nice shock and tends to break things free. The heat helps. Even a propane torch can do a decent job, but propane/oxy or acetylene/oxy does a better job, and if nothing else soaking a 70** rod in water and hitting it with 140+ amps will really get it glowing fast.

I use the 1/2" drive set I have. 13 mm 12 pt socket on an 18" breaker bar with a stubby extension....they come out like buttah :D Jeff Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 21, 2006 Share Posted June 21, 2006 mjeff... how in the WORLD do you get those stupid hub bolts off!!!! theyre torqued like crazy, and the one behind the center cap too... how?! One behind the centre cap as in the spindle nut? Have fun with it. I broke two 1/2" extensions trying to get it out the way I normally would. Finially I said f' it and bought an electric impact wrench. A good one... Link to comment Share on other sites More sharing options...
87manche Posted June 21, 2006 Share Posted June 21, 2006 I have a 36" breaker bar and a 1/2 drive impact socket for those. I will eventually upgrade to air. Impact, or a really big breaker bar Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 21, 2006 Share Posted June 21, 2006 Well, when I broke the extensions I was using a breaker bar with 60" of square tube slipped over it for more leverage. *Snap* Link to comment Share on other sites More sharing options...
87manche Posted June 21, 2006 Share Posted June 21, 2006 Well, when I broke the extensions I was using a breaker bar with 60" of square tube slipped over it for more leverage. *Snap* damn! Yours were on tight! Original perhaps? Mine had been changed, the nuts were loose, explains why I had to replace bearings. New ones got torqued to spec, I hope I have an impact to get them off when the time comes. Link to comment Share on other sites More sharing options...
DirtyComanche Posted June 21, 2006 Share Posted June 21, 2006 Nope, they'd been off about a month before to do a gear setup. Only thing I can say is I'm glad I wasn't trying to change a shaft when I discovered they were that tight. You shouldn't need impact tools to get them off... But if they're seized or overtorqued, have fun. Link to comment Share on other sites More sharing options...
pingpong Posted June 22, 2006 Share Posted June 22, 2006 The best way to remove the 36MM is with air tools. If you don't have access to them buy a Quality 1/2 or 3/4 breaker bar. Use lots of PB blaster, or liqiud wrench. makes life much easier. As for how to pull the front D/S. I had the same problem alll of you had. My solution was to use a 6pt 8MM that I had shortened. Then I took a grade8 3/8 bolt and gound it down to fit in the 1/4 inch drive and shortened it. Now I can put a long box wrench on that and give it hell. Heta will also work, but you stand a chance of messing up your front CV d/s, and ruining the front out put seal in the t-case Link to comment Share on other sites More sharing options...
