Driving without Axle shaft

I broke a u-joint this last weekend, been driving around without the passenger side long & stub shaft in. Im curious can or does this effect the speed sensor in the unit bearing? Asking as my Cruise control has stopped working at the same time the shaft & stub shaft were pulled.

Thanks.

STOP. The stub shaft holds the unit hub together. The unit hub will separate, and the tire will fall off without the stub shaft installed.

Thanks for the warning, but this was true on the TJ unit bearing's, the JK unit bearing you are supposed to be able to drive on without the stub shaft.. regardless it is now parked until my parts come in, I am just trying to find out if the lack of a stub shaft is causing my Cruise control issues.


Thanks

You can drive without the stub shaft in a JK, but removing the inner shaft will open the diff axle seal up and you will/may loose fluid out the axle housing...

The ABS sensor for wheel speed is inside the hub. Removing the axle shaft will have no effect on the speed sensor.

See this thread for a picture of the disassembled hub: http://www.jeepforum.com/forum/f96/o...23/?highlight=

When the joint went did it damage the wires, I had something damage the wires when off roading and all the lights came on as you describe. I spiced the two wires back together and it's all good.

A rag stuffed in the axle tube will solve the lack of inner axle issue. I still wouldn't drive anywhere, on any D30, without a stub shaft installed.

Not with your XJ, but it's completely OK with the JK.
The 2wd JK uses the same hub as the 4wd, and it goes everywhere with no stub shaft.

If your traction control light is on, it will cause both to stop working. It's safety disabled in the ECM

I can't recall if the tone ring is on the shaft or in the bearing.

I don't remember anything on the front axle shafts, must be in the bearing? But it could be measuring the speed of the inner portion of the bearing and it's not equal to the speed of the wheel. If so that would definitely piss off the system.

On the front axle it must be in the unit bearing, because it isn't on the axle shaft....



So if I click the traction control button, there by turning on the light, the cruise wont work?

There is 2 lights on your HUD. TC "off" and TC/ESC error. The error light is right next to the normal one and looks the same, just smaller. If your error light is on your systems fall into safe mode and become disabled. If a tone ring isn't reading, IE no movement - you'll get the error

I guess you didn't look at the thread I linked to for you.

It shows the tone ring inside the hub, where it mounts to the spindle, which makes it spin at the same rate as the wheel.

Yes I looked at it :-)


At this point I am leaning twords maybe I didn't get the sensor plugged back in / screwed down all the way or something. Guess I will find out when I get my new stub shaft and u-joint put together and reinserted.
