Axle Pivot Bushing Size Help

[1983idi]

Have 3 sizes to choose from on rockauto. 5/8 9/16 and 1/2. I figured I would just measure the outside of the threads on the part of the bolt that sticks thru the nut and I came up with 9/16 but just wanting to check that I am measuring correctly because there only is 1 available on rockauto that's listed as 9/16 and if the bolt had a non threaded part that has to go thru the hole that may be bigger?

I can't have the truck torn apart for days on end otherwise I would just pull them and check the ID of the hole in the bushing.

Loosen nut, tap bolt enough to measure shoulder that goes through bushing.

Dang. That's so simple yet so helpful. Thanks!

Hopefully this helps someone in the future. I appears as there are really only 2 sizes. The ones listed as 1/2 and 9/16 all have a center bushing hole spec of around .57" for whatever reason most brands call this 1/2 but some call it 9/16 which is actually more accurate.

I ordered Moog K8672 which is listed as a 1/2" but again spec for the center hole is .57 for this part and my bolt diameter measured at a few thousandths less than .57. If I run into any issues I will update this thread but I think I'll be good.
