Bolt removal on Front Axle Bearing Extension ????????????

[InTimadator]

Please see attached pictures and anyone have any ideas on how to remove bolts. This machine was used and abused by salt water and previous owner. I had to grind off bolts to remove snowplow and this is what is remaining ?100_0654.jpg

Weld a nut to them and then you can get a wrench / breaker bar on them. Soak them good with PB Blaster for a couple of nights and hope for the best.

What Mike said, exactly. We deal with this kind of thing several times a week where I work and just what Mike said is how we deal with this problem. If there is a way to get the blaster to the threads on the other end, soak them good too. It rarely fails to work. Good luck.

rusted bolts

Looks like you probably have a good many more problems with the looks of the bearing extension housings. If the process of welding a nut on the studs does not work as mike suggested, grind all the bolts heads off where you can get the PB blaster to soak around the stud for a day or so then tap housing with a heavy hammer to break the rust loose around the studs and chances are the housing will slide off the studs then you can take a pipe wrench to the studs sticking out of the frame.Of course you will also have to remove the bearing flange and axle as well. The studs will probably be frozen within the extension housing and if you are lucky there may have been antiseize on the bolts when installed. This has worked for me in the past when all else faild. Best of luck!

I just heard of a product but I cant remember what it was called. Real helpfull huh, lol. Anyways it sprayed something cold and worked with expansion and contraction like heating it up but opposite for when heat will ruin stuff. You chill it, let it sit and chill it again in cycles and the cycles are suppose to break the fasteners loose. May help? May not? Just a thought. I will see if I can find it again and update product name.

Good luck.

What the heck happened to that thing? its supposed to big a hunk of aluminum.........that thing looks like you dug it up outta the ocean floor!! lol

When you get the nuts welded on don't try forcing the bolts. After they have cooled, soak them with PB again and work them back and forth with only enough force to wiggle them. Smack 'em with a hammer on the end and spray again, the tapping should shock them loose and they should begin to move. If you have an air compressor blow the loosened material out so it doesn't bind the bolts as they try to come out. I wouldn't recommend using an impact, they usually just break the bolts off. A little heat also helps... sometimes.

OK, its called loctite freeze and release. Says rust is bigger then steel it was made from causing the bond of fasteners. Usually heat and cool, heat and cool will pulverize into powder making it looser allowing penetrating oil to soak in. But this does it opposite the torch. In article in popular mechanics. I found this on line though.

Now THAT looks nasty

I would try the welded nut trick too.

welded nuts work not bad. If that does not work try a washer and a small pipe wrench. Sometimes with the nut you can not get a good weld. With the washer you can get a good flat weld. A guy who owned a muffler shop said that on a stud or part of one he had much better success. Works for me.

I should have mentioned in my last post that once that nut or washer is welded on and still no movement,and after you have soaked the livin' sh-- out of it ,heat the aluminum with a heat gun. It expands the aluminum before the steel stud.

Is the axle out yet? How do the bolts on the inside of the tub look? Is the frame on the inside the same way? Take a mirror and a light and inspect the frame and pay close attention to the front of it. When saltwater gets in it is devastating to metal and aluminum part. The bearing extension is a mess, i would not use it again anyway. So sawzaw the thing off where you have enough bolt to work with. This may sound brutal but how much time have you spent and are still at square one. What year model and type is it. I hope that the whole machine does not look that way. If the body is in good shape and the frame is crapped out a new frame may be the way to go. Floor pans and internal structure may be compromise. If you have front and back bearing extensions and they all look like that your problem has just been multiplied by 4. It is shame that people treat equipment like that. Sorry to sound like the grim reaper. Wish you luck pal.

Front axle bearing extension bolts 66 % !!!!!!!!

Well tried the washer nut welding trick got 4 for 6 . One stub is flushed off may half to drill and tap ? The other one will get the welding trick tomorrow. Everyone say an argo prayer ! Thanks for all the feedback guys. 100_0666.jpg

I Got it !!!!!!!!!!!!

Removed 5 bolts with welding trick and impact gun. The 6 th was almost flush so i ground off with grinder. Hit with rubber hammer and loosened extension. Dropped skid plate and beat extension with rubber hammer counterclockwise and out she come. Punched out bolt on vice. End of storey. Hope the other side is this easy !!!!!!!!!!!!!!!!!
