Throwing this out to the community for help.

 

I'm looking to buy/borrow/copy the driver used to release the rear wheel bearings from an EA-series trailing arm.  I've got two sets of wheel bearings that need changing and I'd REALLY prefer to not use a punch to break these guys free.

Any leads you can provide will help.

I think I remember somewhere on here where somebody modified a hub tool from a 4wd Ford to work. Might poke around and see if that will work for you.

I have one of the official sockets for them. It will work if the nut isn't stuck. For the tight ones, I modified a tool for my air powered impact hammer. Ground the end so it could hit the notch and not deform it. Buzzed it enough to get it to turn, then the socket did the rest.

 

I used by HD Dremel tool to cut the staked edge out, otherwise forget turning it.

DaveT, are you willing to loan out that tool so I can copy it?

Or perhaps DaveT could give dimensions, materials, and pictures so the tool could be accurately fabricated?

The socket one? I think I can make up a drawing later tonight.

I have one, but it's buried from moving, and I won't have time to look until after the holiday.

 

 

I know someone just found a socket with the appropriate OD, and cut it out until the 4 teeth were left.

this.

 

there is a 2 pin socket in appropriate diameter available at most auto stores.  I think it is a Ford tool.  But it's hte same diameter, and has 2 notches directly across from eachother.  It's enough to work.  Don't need all 4 notches.

Hey DaveT, I sent your drawing to a friend to have him cut it for me and he asked what the thickness of the back wall would be, since it's not on the drawing.

Thanks!

Here's one I made from tool steel yrs ago.

Make handle approx 16" OAL with 3" dia. head, 1" wide handle, 1/2" flat stock with 1.375" hole thru round head of handle. Turn round stock to 2.437 OD x 2.062 ID x .250 depth, drill 1.062 hole thru center then mill 4 'teeth' to .250 width, hair over .750" apart to fit nut. Weld this hub to handle. Weld the 2 pieces together with 'teeth'  at approx 20* angle to handle. 

Fit over axle stub engaging nut & apply BFH to loosen nut.

That socket is out there. About 20 years ago I bought a pin socket that was a perfect fit for my XT6. Problem is I can't remember from where or how I seleted that particular pin socket.

Oh, 1/4" thick would be enough.  Be safer to go 3/8" .  If you need more torque than that can handle, you'll probably need to go with my custom air hammer bit to break it loose.  It is difficult to get enough force holding the socket engaged with the nut when large torque is applied.

CZNY, that tool looks great!

DaveT, thank you!
