The most common cause of steering vibration at that speed would be either an out of balance tire, bent wheel or a defective tire. It is also possible that there could be a bent or worn front axle (half-shaft) or worn CV joint, but although those things also happen quite frequently, that's not quite as common as a cause of front end vibrations.
steering wheel
the dealership told me that it is due to the steering column needing to be lubricated
Steering Wheel Air bag!
There is no powersteering fluid. It is electronic.
Your Vue has electric steering therefore there is no pump. If you have no power strg you have an electrical problem........with the power steering unit or wiring to it. Troubles codes can be read for the steering to help in diagnostics
The power steering is controlled by the body control module. There is no fluid.
Saturn Vue was created in 2002.
If it is a whining noise, the vehicle is low on steering fluid or the power steering pump may be going bad. If it is a clicking noise, the CV joints may be going bad. NOPE a Saturn vue has electric power steering and no pawer steering pumpA Saturn vue has 4 stabilizer links and they are made of plastic Moog makes metal replacements for the front but the rear still come from the dealer and are plastic they wear out and make noise when you turn replace them and the noise should go away
The Vue doesn't use power steering fluid. The power steering system is entirely electric and requires no maintenance. If there is a problem with the power steering system, the Malfunction Indicator Light with the icon of a car and a wrench will light.
I needed new brakes when my 2003 Vue shook at 50mph. Once I had the back brakes changed the shaking stopped.
Zero, a Saturn Vue is fuel injected.
Check where steering column passes thru floorboard then lube the shaft where it passes thru the rubber boot.
