Socket Size For Nut On Rear Of Dana18?

I need to repair the transfer case parking brake on my 71-5 with the stock Dana18. I know it's a crappy brake at best but I plan on repairing it. I have removed the rear drive shaft and now need to remove the large nut holding the brake drum in place. What size socket will I need to remove the nut? I plan on hitting a pawn shop or the second hand tool seller (side walk vendor in East L.A.) to buy a single socket.

 

Gah. I just did this recently, and I literally can't remember if it was 1-1/4 or 1-5/16. It was one or the other to the best of my recollection.

 

This is word for word what I wanted to post.

 

Just tackled that 1-1/4"

 

Thanks,
Nick

 

I think there are 2 different style of nuts.....1 1/4 and 1 5/16.

The one I just did had a castle nut and it was 1 5/16...Richard

 

try 'em all until you find the right one.

 

This! It depends on what size nut you have. 1 1/4" or 1 5/16".

You can get a set of 1/2" Impact sockets at HF for cheap.

 

yep. they're pretty good for what we do with them.

 

Mine turned out to be 1 1/8". The brake shoes are missing over half of the braking material. Rivets are there but the rest is gone.
