How hard is it to change front wheel hub/bearing?

When I apply the brake after starting the car I tried to shift out of park but it feels like the lever is not catching on something and the gears don't shift. The lever moves freely from park all the way down to all positions but the indicator light says it still at park. What could it possibly be as it happened suddenly the next day after I used the van. Tranny has no problem then this.

Need info on how to pull the oil pan down and replace the oil pump. Where is the oil pump located? Is it in the pan as I have heard it may be external.

This afternoon while driving a load of kids to jazzercise my side airbags deployed for no apparent reason. We weren't even moving at the time of deployment; I was stopped at a stop sign. My son was in the passenger seat and sustained a burn on his arm as did I on my hand.
Has there been any other issues of random deployment of an airbag on the ventures? My venture was new in 2003...and we LOVE it. Am missing it while it's at the dealership! Any ideas? thanks!

how do we adjust the rear whipper is not hitting the window right?

I'm replacing the intake gaskets and when I have to put the push rods back is there a best way to torque the rockers? I have an inch pound wrench. Do you just tighten them up or do you have to turn the engine over? I'm a little unsure of this part. Thanks

I'm still trying to get this right. I was wondering if it was a good idea to use a gaket sealer when replacing these gaskets, like form a gasket or rtv? Also if the aluminum is pitted should that be filled with a sealer? thanks for your help!

I've heard that the chevy dealer has a better gasket to replace the old one but Napa told me they called chevy and they have the same one. Does anyone know for sure? Napa has felpro. I don't want to do it again. Thanks-K

I think my intake is out or maybe the head gasket or both. How do check to know for sure? There is no water in the oil.

how when should the timing chain be replaced?

We have a a big problem with the engine light coming on alot. When it comes on u feel the van bucks abit and then after a bit it loose all power and shut down. It always starts again right after. The garage has scoped it many times and the last time which was friday Nov 5 2010 the scope said the mixture is to rich . What does this mean.
When they do the scoping it turns the light off for 2 days then it is back on. The garage doesnt really know what is going on.
