HELP ! from those who know first gens?!
 

Hey guys, i figured this would be the place to ask becuase im about to strangle the parts guys in my town here.
im doing a brake job on my 1990 w250. rear went fine becuase i had the 2 &9/16" rounded hex socket (took three times from a part store to get that right)
now when it comes to the front i can get this far and CLLEEARRRRLY its not the 2 & 9/16 " socket.
so my quesiton, what size is this heffer??
ive tried 2 3/4 but it wont even fit in the hub and obviously 2 9/16 is to small and rounded
and please dont tell me its a 2 & 9/16th or ill cry

I don't know what size it is but if you cant find a socket to fit it then you might try a hammer and chisel.

I don't think that's the right nut. Mine looks completely different and uses a socket that has pins that engages slots, not flats on the nut.

I'm thinking that's the older type of nut from a 1970s REAR axle.
In that era Dodge (and other makes) used 2 really thin nuts to lock the rear hub bearing in place.
This appears to be one of those, but don't take me literally on that.

I am not sure of the actual size, though.

Mark.

those spindle lock nuts look like the ones you would find in the early external hub dana 60, hate to say it but i think they are a 2 9/16

No
 

I have the 2 9/16 r socket it is 100 percent not it.
the socket fits the rear not the front

Even if the size is 2-9/16", your socket won't fit because it has round corners.

hey just saw this thread anyways when I did this on my 93 I went to NAPA and got a dodge dana 60 front axle nut socket. It was the only one I could find that fit it
