Something to mull over tonight.
I had my X in the air on some hover pads today so I figured I'd get this on video.
Ran it, put it in drive, stopped the rear wheel with my hand. The other side not on digifilm wasn't even moving. http://vids.myspace.com/index.cfm?fu...=700353885&n=2

Did you break your tranny again?

after seeing my wheels swap tourque between each other on the dyno, I want to get the wheels off the ground without any load on the wheels.

Damn I should have went under to check the driveline... You can't see it while sitting on the ground.

The way a differnential operates ( http://auto.howstuffworks.com/differential2.htm ), at least one wheel should have been turning when you stoped it with your hand. If you had a bad rear end, there would be all sorts of nasty noises.
Do you have any CEL on? Did you do this in low? Low forces the TCU to put the car in a 50/50 torque split. From looking at the video, there may not be anything wrong. There may not have been enough of a speed difference between the front axle and the rear axle to active the AWD more then the 10/90 split. Since you dont have an LSD on the front end, its safe to have one front wheel on the ground when you try this again. When you have one wheel on the ground, the opposite wheel will rotate at twice the spedo reading. The rear both wheels would have to be off the ground, incase you have an LSD. If it appears you dont, by stoping the one tire from spinning, the opposite should rotate. The AWD uses two speed sensors to determine that wheels are slipping, one in the spedo head, the other in the tranny. There may have not been enough resistance or speed differnence for a vallid test. Thats just the things i would check, hope it helps nipper |

The opposite wheel did not spin when I stopped that one. I know because it was dragging on the inner wheel well as I turned it. It was pretty loud. It only touches in that suspended position though.
When I was at the rear I had her give it some gas. No change. No CELs, D selected. Something else I should point out, you being new and all wouldn't know, my car can do FWD burnouts. The rears do not push the car at all.

You shouldnt be able to do a burnoout on a sooby awd unless you have a trubo or a supercharger on dry ground. Like i said, try it in low. If you still can do it you have a dead AWD. Test the duty C solenoid to make sure there is no open in the coil (though that should throw a code). Does your Transmission temp or power light work? Could be a burned out bulb. Could be a bad vss sensor.
Now when you say it was loud, what was loud. Did the the vloume change with engine speed (this is all tough without seeing the car). Is it loud when driving it normally (like a roar). louder as speed increases. One other thing to try is a tranny flush, as it is possible that there is junk in the AWD circuit keeping the pilot valve from operating. nipper Last edited by nipper; 05-01-2006 at 08:57 AM.

The fact that he said he can do a FWD sorta burnout in his SVX makes it completley not normal. I can't even do a burnout in my SVX in the rain let alone on dry pavement.

With no throttle input you will not have AWD. There are many factors the TCU considers before transferring power to the rear.

ah but with a properly working clutch pack there is resistance and there for the back wheels will spin lightly but should be able to be stopped by the human hand. your car is working fine as long as your burnouts are no longer than a little chirping of the front tires.

The loud noise was from the rear left tire scraping the inner wheel well as I turned it as it was suspended. It doesn't touch in the normal position. Tranny oil was changed a few weeks ago. It was flushed last year. Quote:

First and maybe only real burnout I did was when my old all seasons still had some tread left, I left a 30ft strip of rubber and blue smoke pulling off a side street and into a turning lane. In the wet box at the drag strip I spun tires all day.
