Lug bolts

Everything old is new again. I have some ancient car hubs with ball bearings that were made into trailer axles. They have lug bolts.
 
Not a new thing. Chrysler Corp cars were all bolt up until mid 60s I think. And,LH thread on the left side! Some bigger GM brands too, in the 40s/early 50s.

I suspect it is all about two things: Parts count and assembly line speed.

I converted my 56 Dodge 1/2T to studs the first week after I bought it! I hate trying to start bolts while aligning the holes.
 
That is why your VW beetle tool kit in that little wraped up tool pouch had a special bolt to start your wheel. Basically a head less bolt about three inches long that screwed into the drum. Hang the wheel on it and screw in the other bolts and then that one. Simple and handy.
 
Newer cars with lug bolts is almost exclusive to several European brands or euro based vehicles. Some have a alignment pin to help line them up and hold them up to the hub, others don't. It would be a pain to change a tire at night trying to hold the wheel up on the hub while trying to line up the holes and then starting a bolt at the same time.

Some of the old trailer wheels also had an extra hole to help align the wheel onto the pinned hub so it would be easier to start the lug bolts.
One of the reason they went from bolts to studs was because threads wear with each use so to minimize cost of replacement it would be better to replace a lug nut and/or lug stud as apposed to replacing the lug stud and/or break drum/axle. Anther reason they went from bolts to studs was safety the bolts work themself loose. But with today's disposable lifestyle mindset and corporate bean counting, penny pinching making one part that lasts for less time and is cheaper to make. Planned obsolescence
 
I?d be afraid to let most of these modern tire techs
change my tires with lug bolts it would be one thing
if they were hub piloted i can see it being ok but stil
not the best a stud Is awfully forgiving a bolt isn?t .
Reason I asked my cousin has a 2017 Jeep with
bolts instead of nuts
 
Actually many used lead hammers too. When the hammer got all mashed up you had a mold. Remelt the lead and pour it into the mold with the steel handle stuck in there . You could collect a couple of those line o type bars from a newspaper for making your heads.

The European theory is that lug bolts are less likely to loosen. Once the Eurotrash car builders have convinced themselves of something, you'll never change their minds. Jeep is a Fiat product, so lug bolts.
 
(quoted from post at 01:49:00 01/23/20) I guess the low riders use them to not my favorite design either

My uncle usta have a few odd quirks too, he always wore a tie to keep his feet warm and a tinfoil hat to keep the voices at bay and he liked low riders. :roll:
 

I don't know..... but back in the late 50s I had a '47 Dodge that the rear end "went out" on.
Bought a '48 Plymouth for the rear end.
Now....I can't remember which was which, but one had studs and one had nuts but both had LH threads on one side.
BTW, the one with studs did have a pin sticking out to help align the wheel when installing. That's why you see those extra small holes on those old Chrysler product wheels.
 
If you have an axle with ball bearings it is probably a Chevy. It took them up to around 54 to figure tapered wheel bearings were better than ball bearings. Stan
 
A better idea by fiat strikes again ! With the quality of personnel working at most tire shops i bet more than one hub has been ruined
 
I'm not sure of the reason but I bet there is a pretty fair cost savings more than just the amount of parts. I used to work for a plant that made front hub and bearing assemblies. When the machine drilled the holes for the studs it had pretty close tolerance. Just a nick on the drill or wrong speed could cause problems. If you checked them and they were out of spec. they were scrap. Than when they went to assembly the studs had to press in with the right pressure or they were scrap plus the parts installed had to be removed if possible or they went to scrap.
 
Yes
I found "GM" somewhere on one of the parts. When I first got the trailer it still had the steering arm bolted to some of the backing plates. Old straight axle stuff.
