Question:

I know that my livestock trailer has 7,000 pound axels and it’s a 8x6.5 hub and is also the 12x2 I know all that, eby the manufacture told me the stud size is 9/16 , so my question is I watch the video for your hub assembly for the 5200-7000 pound axels with 9/16 studs and the guy in the video said the nuts were 9/16 so I’m confused because when I took my rims off , I used a 13/16 socket .. so ether EBY GAVE me the wrong stud size, or the person in the video was mistaken , just want some advice because I’m confused , thank you

Expert Reply:

The size socket used isn't necessarily going to be the same as the nut or stud thread size. It is usually larger since the outer width of a hex head is larger than the threaded diameter. Hub and drum assembly # 8-219-13UC3 for 5,200 to 7,000 pound axles does indeed have a stud diameter of 9/16 and would take 9/16 inch lug nuts.

We also have the similar etrailer model, # AKHD-865-7-1-EZ-K, that also has 9/16 inch studs. Both it and the above assembly are for EZ Lube axles. If your axles do not have the grease fittings at the ends of the spindles then you would instead use assembly # AKHD-865-7-1-K.
