Whats wrong with your axle is the design. Save youself the trouble and go to www.quadratec.com and search for "posi-lok". This will solve your problems.

I think I have a problem as well with mine right now. My front driveshaft is "connected" to the front axle .. when the drivers wheel turns, so does the driveshaft. When the passenger wheel turns, the driveshaft stays still.

My driveshaft used to be fully dis-engaged .. I could spin it freely by hand with all tires on the ground, and I can't anymore.

Any one with ideas on what to look at? Is it the gears, or the vacuum actuator?

That is another design flaw with the D30. The drivers side axle shaft will always spin the differental and driveshaft even if the 4WD is not engaged, but since the transfer case is not disributing power to the front wheels its is still considerd 2WD. Its a characteristic of the D30 that makes for bad on-road handling. The only way to fix it is to lose the D30

your disconect is fine. something is up in the differential. yes your driver side driveshaft is always connected but when in 2wd, your spider gears should spin letting you freely turn your driveshaft. likewise you can turn your both wheels independent of each other and of the driveshaft. if you have a limited slip or places a locker in the front, this will cause you driverside wheel to always spin the driveshaft due to no spiders. If you dont have a limited slip or a locker, then there may be something wrong with your spiders in the front carrier. try to spin the driveshaft while all wheels are on the ground. if it doesn't turn either directions then pull the cover, drain the fluid and check the spiders. make sure they didnt get jammed. if it does spin, than you are ok. it may take some force. dont worry about the spining driveshaft when you are driving if it checks out ok...there is no load on it.

Its not what you buy...its what you BUILD!!!

I think that my front driveshaft is not balanced properly .. anything over 100km/h (60mph) and my front shakes like a leaf in a tornado.

I was thinking the spidergears might be the problem .. but wasn't sure. I will take it apart and verify this real soon (the weather is supposed to be nice soon, so I can work in the sunshine).

Thanks!
