My van is a 2001 E150, and I am trying to do a rear wheel bearing and seal replacement job. I got a new lockpin (with loctite on it) from my local Ford dealer, but I am having trouble getting the old one out. I've got a 5/16 th socket (6 point) with a 1/4 in stub plugged into it, and a 1/4 in box wrench around the stub. It feels pretty good when I fit it onto the bolt head, but the bolt won't move, even with some hammer taps, and the head is starting to round over. Any suggestions would be appreciated.

Thanks.

 

Tried a little heat yet?

Heat and some stiff hammer taps to the head of the pin, it should break loose.

 

Depending on what source of heat you choose to use , you might want to keep a fire extinguisher handy !

 

I will try some heat, probably with a heat gun. Using a torch under there is too scary for me. I also found that there are screw removal tools specifically for this application, because so many of these lockpins shear off when removed.

Thanks guys!
