I need the socket for the nut that holds the front caliper on. I have a 97 pwd 4 wheel drive crew cab. I am not sure what type axle it has. If you can tell me how to figure that out I can probably find the right socket.
Any help will be greatly appreciated,

Thanks, Ed

 

IIRC it is a big metric. 14-18 MM. Can't remember. If it is a independent suspension it is a D50, which is most likely on the 250. 350's have the D60 I believe.

 

It takes a 21 MM socket for the caliper mounting bolts for a Dana 50 which is on the 250s. For a D60 on the 350s I'm not quite sure, but guessing it would be the same.
