Removing bolts for axles. 1991

I am having trouble breaking free the bolts holding the axles in place on my 1991 34ft excella. Presoaked the nut twice with penetrant. I've tried heating the nut with a propane torch and then removing with an impact wrench, and tried to put the end of the1/2" breaker bar on the top of a hydraulic jack and observed the bar flex but the nut will not budge. I've got a couple weeks to figure this out.

Any advice?

I used a sawzall with a 18T metal blade, a few of them.

Or carefully with an acetylene wrench aka cutting torch.

Ok, I might have to resort to cutting the head off the bolt and hammering it through.

Borrow a 3/4" drive socket set and a cheater bar from a friend. You can get much more power/torque with the 3/4" drive.
Penetrant - I like AeroKroil - it is the best I have found so far. Spray the bolts down 2x times a day and let it soak for a day or so. http://www.kanolabs.com/penLub.html
I have heard that dry ice works well,

Nut splitter tool?
Sharp chisel and small sledge hammer
Sawzaw the nut off

great advice here! A nut splitter will help.. the 3/4 breaker bar will help... a better 'impact' wrench (with impact socket) may help..

There is a Snap=On tool.. an 'inductor'.. which uses similar technology as the induction cooktops to heat a fastener.. look on Youtube! They exist!

I am sure they are 'cost prohibitive'.

A 'fire knife' (torch).. NO!!! too easy to mess up ...

I have 'center drilled' bolts before... but it is very difficult..

Now, PB blaster, Aerokoil.. are some good ones!!

With Fire Extingusher in hand.. and a "welding blanket" protecting the underbelly...

I would 'heat' the nut with the propane torch.. carefully.. not so hot the spray will ignite.. then spray with the PB or Aerokoil. When done properly, the spray will cause cooling and also 'pull' the liquid into the threads...

If things get too hot, use the heat gun... it won't get so hot as to flame the spray stuff.. unless you use them simultaneously. The advantage to the Propane torch is you can apply the hot part of the flame directly on the bolt...

Repeat the process on each bolt then come back to first and begin cycle again..

I saw some WD40 with an 'activator' in it.. and it seemed to melt away the rust.. I am gonna get some next time I need to bust a bolt.

If all else fails, or if it is more satisfying than fire (hard to imagine), Sawzall.

I used a Dremel tool to cut thru nuts frozen to shock absorbers several times... just cut as flush to the plate as possible... then knock out the bolt...

BTW.. make sure you have things properly supported.. PLEASE!! you have been REMINDED!

i ordered a nut splitter from amazon for $23. Very hard to find one that would fit the 15/16" nuts locally.
