How do I remove the front axle square bolts? I want to install a front bumper. The square bolts seem to be screwed in since 1939. I removed the nuts now I need to get the square bolts out.
 
I doubt this is the most professional way to do it, but I just use a block of wood and a hammer. I'd also recommend jacking it up by something other then the axle to
take some pressure off.

Yours will look a bit different from the pics but same idea. Taking the whole hood and grill off isn't required, :)

If you can,heat them up and put the nut back on the threads the length of the nut if
possible and leave some room in between the bar,hit it with a lead hammer if available and a
brass drift to drive it the rest of the way out after it once moves and you take the nuts
back off.
 
I hope the shanks are round and not square!

Jack frond end up, liberally apply kroil or similar penetrant, put nuts back on a bit and beat on them. If they move some, re oil, beat them back the other way, etc.

Sometimes an air hammer helps.

If that dont get it, put the gas axe to them and get them red hot, then oil quench, he's again, let cool while you set torch down then wail on them. If still nothing, cut he's and shank off, split axle haves with chisels or air hammer, if the shanks still wont budge out of one or both leaves, burn them thru with your gas axe.
 

Thank you for your reply and the helpful information. The bolt heads are square and the bolts are so tight that I thought that they might be threaded through the axle. I am soaking the bolt with oil and I have a torch if needed. David
 

Thanks for the photo and the detailed information. I have a torch and I will try heating the area and beating the bolt out. David
 
I had to deal with the same thing-what happens is that where the axle pieces are sandwiched
together, they move some all the time and basically form a wear ring inside--creates a
shoulder..try turning the bolts to different positions--jou might find a sweet spot and the
bolts just might drive right on out without major effort..As others have said, first get
the weight off of the front wheels..
 
Thank you for your reply. I will get the weight off the axles and try pounding it out. David
 
They rust in there and can be a bugger to
get out.
I wouldn't bother with heat.
You'd need a rosebud and get the whole axle
pretty hot to get them out that way.
First of all, as others have said, get the
weight off of it.
Then accept the fact that you aren't going
to save the bolts.
Take a 12 lb hammer and slug them a few
times. I wouldn't even bother with anything
smaller.
Once you get them loose take a grinder with
a slitting wheel and cut the mashed part
off. Then use a drift and drive the rest of
the bolt out.
It's about a 10 minute job to remove all 4.
 
I went through this with my 8n last winter. Here's what I did that worked for me: First, be patient. Forget the torch and the BFH for right now. Squirt everything down with penetrating oil. Loosen the nuts but don't take them all the way off - two or three turns out at least. Go away for a day or two. Come back and squirt it down again. Get the weight off the front end. Get out the BFH and rap hard on the nuts (not on the bolt ends). Turn around and bang it on the bolt heads. Squirt it down again. Set it back down on the ground. Now, take it out for a ride over some really rough terrain. Go for a long ride. With my 8n, the field rides did the trick. I did this in two or three repeats over a couple of weeks. Letting the frame parts have a chance to wiggle seemed to do the job for me. This takes time, but it avoids BFH damage and Blue Wrench damage. Replace the bolts with new ones. Good luck!
 
Thank you for your response and the information. I am flooding the bolt with a 50/50 mixture of ATF and Acetone and I have unweighted the front axle. I loosened the other bolts on that side and the axles are separating a bit so I can flood the bolt between the two axles. I drove it around the property a bit today but the bolt still seem to be welded by the rust. I have exersized the bolt joint by un-weighting the bolt with a floor jack and then lowering the tracker back to the ground. Hopefully the ATF will work its way into the bolt and release.

I will keep soaking it for a few days and then put the torch to the axle. Thanks again. - David
