thats strange!

[rostheiceman]

so yeaterday iwas putting some new tires on and i had the back of the truck up on jackstands and i found the even with the truck in park the axle spins free the drive shaft doesnt spins butthe axle does. now i know this is not right the truck drives fine but this is a little strange.

Thats completely normal if you have an open differential. The wheels can spin in park as long as both wheels are off the ground. The opposite wheel will be spining the other way.

 

[rostheiceman]

well thats good to know but i thought the 9inch was limted slip

 

[Roadkill]

Some are, some are not. Sounds like you have the latter. /emoticons/[email protected] 2x" width="20" height="20" />

Also, a limited slip is just that... limited slip. If you push it hard enough, it will slip. If you do have a limited slip, it could also be that the clutches in there are worn out, you truck is 26 years old after all. In that case it would also behave like yours is.

You need a locker, that'll fix it

 

[rostheiceman]

how does a locker work anyway?

 

[Yardape]

I was joking, a locker locks the axles so the both turn the same way. Huge improvement in Traction for off road. If you notice when you turn one tire the other goes the opposite way. With a locker the both will turn the same direction.

Lockers can be real exciting on paved slippery roads

sea bronco i know this will sound dumb but i gotta ask what you meant by that.. i was thinking about lockers but i know little about them..

 

[BB33's]

I think he was talking about sliding. A limited slip will let one wheel SLIP and let you make a smooth turn around a corner where as a locker makes both tires want to be the one suppyling traction and will drag you around a turn causing chirrping. In wet wheather this is only enhanced and all you get is both wheels spinning very fast and your truck sliding around like a puck on an air hockey board.

 

[love_my_bronco]

ohh ok chirrping? i get the slidding factor but never heard of chirping.. guess i learn something all the time.

lmb,

Imagine one circle inside of another. The distance around the inside circle is shorter than the distance around the outside circle. So now imagine that one makes a turn with his bronco. The tires on the inside of the turn will go a shorter distance than the tires on the outside of the turn, and since they will get to the end of the turn at the same time, the outside tire has to turn faster, or the inside tire has to turn slower, or both. An open rear, and a limited slip rear allows them to spin at different speeds, and both tires stay in contact with the road.

On the other hand, if one has a set of lockers, and they are engaged, the left and right axles are rigidly locked together, and both tires WILL spin at the same rate. Something will have to give when one makes a turn, and what gives is the tires slipping on the pavement. This gives excessive wear to the tires. On dry road the chirping sound is like when one slams on his brakes and skids, but just in short little hops. On wet pavement, it is possible that BOTH tires will give a little bit, and one can find himself sliding all over the road, cause every time he makes a turn, he is in a skid.

Here is a thread on the different types of lockers.

thanks Joe. that makes alot more sense. and thanks for the link. helped me out alot. i was afraid to get lockers there for a second. didnt want to risk tires over lockers. Ha.
