wheel bearing / hub removal HOW DO I BREAK THIS NUT?!!
 

1998 v70 GLT, Front wheel drive, auto trans. 200k miles.


I'm in the process of changing the front wheel bearings/hub assy. and am trying like hell to get this nut off. You know the center nut ~36mm that holds the drive-shaft to the hub.

I'VE SOAKED IT IN PENT.OIL, USED AN IMPACT WRENCH AND STILL NO LUCK.

IS IT REVERSE THREADED? WHAT IS UP WITH THE "EARS" ON THE INSIDE OF THIS NUT?

ANY ADVICE?

Also, while this front end is apart any suggestions on other items to replace while I'm there. The car just turned 200k


Thanks.

REALLY LONG BREAKER BAR AND PIPE WITH THE TIRE ON AND SOMEONE HOLDING THE BRAKE. MAKE SURE THE CAR IS ON THE GROUND AND IN PARK AS WELL.

It should break loose then.
Inspect all parts while you have everything loose.

tech,

I don't really understand how that would be done. How would you get the socket through the rim? Also I already had the discs off, not that they would be hard to put back on real quick.

Anyway, I did manage to get it loose by applying heat to the nut via a propane torch (plumbing tool) for 25 seconds or so then, before the nut cooled i immediately ran an electrical impact wrench followed by a pneumatic impact wrench. It took like 2minutes total.

The heat is a trick I remembered from watching my dad take apart his Ford Model-A, some of these bolts had been in place for like 80+ years so they were on pretty good.

Thanks again for the advice tech. It's always helpful

Some of the rims have the big hole or you could have installed the spare.
