put some heat on the bolts using a butane torch. Keep a fire extinguisher handy, as well as a wet rag over rubber parts.

A box end wrench should not break without termendous tq. What brand of wrenches are you using?

 

Get a small torch and heat up the bolts closest to , and inside the casting , works every time .

Get yourself some real penetrant , PBblaster , that stuff is amazing

 

ill try the heat and pbblaster, thanks. The wrenches i was using were cheap costco products i think, they broke while hitting them with a sledge so doesnt really suprise me.

 

Also, try using a 6pt socket with a breaker bar. I assume the bolts are 6pt. If they aren't use the proper 12pt socket.

Also, I know desperate times call for desparate measures, but a hammer on a wrench never ends up the way you want it to.

Try the heat meathod. It works everytime I get annoyed with something.

 

If you're using a wrench don't hammer it. Try doubling up on the wrench (end to end) for more leverage or even slide a pipe over it. leverage is your friend

 

x2 on what the previous poster said. When I had to do this the first time it was h*ll! Get a breaker bar with a 12pt socket and a long pipe to act as your helper while doing this. Also, jack up your front end and rotate your wheels both ways to get more room to work.

BTW-Do yourself a favor and put some anti-seize on the bolts when you reassemble it, you'll thank me later.

 

cut the heads off buy new bolts and wheel bearing

 

You obviously haven't price a new hub assembly, have you? There around $90 new from Rockauto.com

 

there probably $300 canadian up here but if you can't get it out then you need to do something

get a good 1/2 drive 12 point impact socket and a long breaker bar
spray the bolt where they go into the hub (a few threads stick out)
I like to use the ZEP penatrating oil seem to have great results as long as I give it some time to work (overnght is awesome)

That's similar to what I do. A box wrench or 3/8" drive ratchet won't cut it. A 1/2" drive ratchet with a 12 point 13mm socket (good quality socket, cheap ones will just round or crack), PB blaster, and heat. Usually I can get them easily with what's listed. If not, a cheater bar always takes care of it.

 

Use the 12 point socket and a 1/2 inch drive. Soak in PB Blaster for 1/2 hour. Then tighten the bolt - then untighten with a long breaker bar. If you apply heat, apply it to the area on the hub assembly that the bolt screws into.

 

PB Blaster is one step above WD 40.

Liquid Wrench or Kroil works better.
