What is the thread size on the front axle spindle? having hard time with the nut so I was going to chase threads.
1/2" x 20.
Nuts are 3/4" x 16 but are left hand thread and right hand thread , be sure you have the proper spindle nut.
There is a left hand thread on one side, and a right hand thread on the opposite side. make sure you have the correct nut for the side you are working on.
The size I gave is for the thread on the spindle bolt. Looks like I misunderstood what you were asking for. I apologize.
I made the same connection RV.
The left hand threaded nut should be on the right hand spindle, the right hand threaded nut on the left side spindle.
Hope this helps.
