On my '84 4x4 F250HD (8600# GVW, Dana 60 rear axle), the wheel studs on the left side are indeed reverse thread.

Having a brain fart and can't remember for sure if the front axle also has reverse thread on the left side, but the rear axle certainly does.

I'm not too concerned about the drum clearance issues now; I'll just make up two thin walled sleeves to press onto the hubs so that the drums locate centrally, & then press the new lugs into place.

Thanks again

maybe you have a spindle or a bearing issue? I saw a thing where those drums are easy to over do the preload and then the bearings wear down from that

It was figured out years earlier that you did not need the left hand threads to keep the nuts from loosening. But I guess the factory was still setup for that on that axle and they kept doing it. Chrysler was one of the last OEM's to quit using left hand threads.

I suffer from VCS (Vehicle Confusion Syndrome). Got my vehicles mixed up. Had to go check. All have Dana axles.

My '84 F250 and '63 Jeep have LH threads only at the left rear.

My '48 Jeep has LH threads front and rear on the left side.

In the old Jeep world, I've heard plenty of tales of woe about studs breaking during wheel removal, with the owners unaware of the LH threads. The studs have to come out for drum replacement, too. Heard a few horror stories of LH and RH studs getting mixed up at the same location during reassembly.
