Rear wheel lug issue

[Rexster]

I was told by the techs at the dealership that the passenger side, rear wheel is the primary drive wheel on my 2020 2 door Wrangler Sport S. Is this true? Snapped lugs off ruining the wheel after new tires mounted.

The rear axle drives the vehicle in 2wd if that's what you are asking.

Yes, you need to have rear lugs, nuts, and wheels to safely drive the vehicle.

It does feel like the rear passenger is the main wheel indeed, but hard to say with the BLD nowadays.

In an open differential, whichever side is on the inside of a turn is driving.

Not sure why it matters, snapping lugs is most likely an installation error.

I find my rear driver's tire wears the fastest, but as to which of the rear tires it's probably the result of tiny variations between tires, axles, vehicles, etc.

More details please. This occurred after driving about how many miles after having new tires installed? Or was it during installation? Wheels and lug nuts are OEM? Improperly torqued lug nuts, way too loose, or way, way too tight might have been at fault.

Just jack both wheel on the back disable LSD and BLD and look at what wheel will spin when you apply throttle / rotate the shaft. the wheel spinning in accordance to input direction is the primary wheel. it is also the one that will do the burnout

So we’re thinking the 3.6 minivan motor has so much torque at the rear wheels it can shear wheel studs. I know mine doesn’t

Both rear wheels receive the exact same amount of power. The passenger side wheel tends to appear to be the primary due to the rotation of the engine, transmission and driveshaft.
When torque is applied the rotational force forces the drivers side of the axle down and the passenger side up, thus increasing traction on the drivers side and reducing traction on the passenger side which results in that side tire spinning easier.

The other day I did some "11" while trying to insert myself in traffic, ya color me surprised on that one.
On semi related topic bleach, under power 3 cyl engine and 14'' tire make for some nice smoke show lol

how you explain one wheel burnout if both receive the same amount of power ?

One breaks traction first, then that one receives the majority of the power.

Than they do not receive the same amount of power if one receive 100% of it.
Technically the power go to the first wheel and is meet with resistance than bounce to the next one and is also meet with resistance and will go like this until the power is even between both wheel.
Before the electronic nany it was not uncommon to have one tire with more wear and it is not because the brake was not calibrated properly

Now maybe I should clarify I do not believe is stud got sheered because of spirited driving. I only answer the question of what I think is the strong wheel on the JL from experience. Certainly did generate some nice conversation

I thought I did a decent job explaining it in my previous post.

Ok, but if both receive the same amount of torque they should both have the same rotational force pushing both of them down no ?
