Should my wheels spin when the truck is in park?!?

I had my rear end up on jack stands to change out my wheels/tires, the truck was in park, and it didn't take much to get them to roll in the air. Should they do this while in park? I would think not but I don't know.

Yes your tires should spin freely when both are off the ground. When you spin one tire, if the other tire spins the opposite direction or not at all you have an open carrier.

if in park, and 2wd the rear wheels should not spin, at least one of them, depends if you have an open carrier or not. the front wheels will spin 100% free

in park and in 4wd then the rear is like 2wd and the front should not beable to turn

Open diff Yes one tire will spin and the other will go the opposite.

Limited slip, Maybe. My Level II would spin opposite until you kind of jerked the wheel back and forth, then it would lock and not spin.

That's why I said maybe. The Torsen on the 04 would sometimes. The impala with the eaton won't and an old station wagon I used to have would.

The brakes are in no way connected to or controlled by putting the truck in park. There is no way to activate the front brakes without stepping on the brake pedal.

Maybe you should not think so hard. That statement was so far from reality, it should never have been included as technical advice.

Putting an automatic transmission in park will only prevent the driveshaft from turning. The type of differential will control from there how and if the the rear wheels will turn as has been already stated.

not possible... watch mythbusters, even reverse doesnt do anything to slow the car down....

im almost positive our trucks have a parking pin that locks the gears....


and if both spin in park then park on a hill and see what happens heh...

watch mythbusters why what did they do?

My wife used to have a 98 explorer which had the same drivetrain as my 98 ranger. She went from D to P one day and the ex stopped, tires locked up and skidded to a halt. Tranny was never the same.

^^^^My GF did that to my blazer, it just made a loud clicking sound (we did stop fast, but the tires didn't lock) I think it is a safety feature on the 4L60E....

tried to get a manual trans and an auto to stop/slow down quickly by throwing it into park or reverse.... both were unable to go into park/reverse at something like 40mph

They were trying to break the drive shaft not stop the car, I think

First mythbusters are not always right. I love the show but they go back and revist myths because they get some wrong the first time. Second not all vehicles are made the same.

My wife was only going 25mph when she did it sooo I guess the mythbuster's test doesn't apply to her situation.

Most relatively modern automatic transmissions have some safety interlocks to prevent it from being shifted into reverse while the vehicle is moving over a certain speed. The same thing will prevent it from going into first gear while you're cruising at 70mph.

Park gear on the other hand can usually be selected at any speed. Depending on design, you're either going lock up the wheels or the U-Joints will snap and you keep rolling.
