i have a 2002 ram 2500 and the axle nut on spindle is stuck on have to replace wheel bearing and i really need to know the actual thread pitch and inside diameter of the nut so i can get a new one and dodge doesnt have them please help

 

I would take it to a shop and have them break it loose with air tools, then you retorque it so it can be removed when you get home. when they break it loose, spray it with penetrating oil so it'll come off easier.

As for the pitch, I would check the other side or yank off the other side so you can go match it up. Wrecking yards are good for that kind of stuff...

 

if the dealer doesnt have them, i would look into the junk yards, the chance of a parts store having a castle nut in that size is rare, i cant tell you the thread or pitch but i do know that the 1/2 ton trucks also share the same size nut...
