2002 envoy fan clutch siezes
What is the outside air temperature when it locks up? Summer temperatures will cause it to lock up much sooner which is normal. If this is not the case you can get a replacement fan clutch at any auto parts store

Transmisson shifting find but sound like airplane
When the engine sounds like an airplane, the most common problem is your fan clutch. It's not dis-engaging, all of us have had that problem OR will at some point with this vehicle platform. Replace the fan clutch.

My 2002 Envoy started knocking on the way home and the oil pressure dropped om the gauge.
I wouldn't drive the vehicle till you find out what is wrong. Have you ever changed the oil and filter, plus, overall tune-up?
Is this high-mileage engine? You could use an analog gage in place of the oil pressure sending unit, just to double check the gage. If no oil pressure, could be the oil pump? If this is a high-mileage engine replacing the oil pump may not help. You may need an engine overhaul. Do you have any cylinder compression?
Because that knocking, hope you don't have internal engine damage?

Vibration in front end especially after 40 mph
Hi Randal:
Odds are it will either be brakes, bearing, or drive shaft.
You'll need to jack it up, make sure it is supported safely, and check the brake pads and rotors. Then check the drive shaft cv joint and the bearing.
Cheers.
