Turning to the left hearing a rattle noise in the 97 toyota avalon ...went to the shop and they changed the power steering fluid and that was good for awhile ...but restarted the car and have the same sound again

They will whine if level is low or when fluid needs replacing. Try checking level with wheels at center position.

hi there stephanie. if you haven't already. i should have the power steering pump checked out. it sound suspiciously like the pump.
good luck .

If the power steering fluid is ok then just about the only thing that this can be is a defective power Rack and Pinion steering gear assembly. Since this part is very expensive and a front end align is required if it is replaced have a front end shop or the local Toyota dealer confirm my suspicions.

Please check the power steering reservoir and make sure that you have adequate amount of power steering fluid.

Hi there !

The noise is coming from your power steering pump, And it usually happens when you have low power steering fluid or burnt fluid or bad Pump. check for fluid level and make sure its not black. Good luck

If you think the tyres are in reasonable condition get the wheels balanced. If the front tyre/wheels are out of balance you get shake in the steering wheel at certain speeds. Backs out of balance are usually felt through the seat.
I cant see a connection between the power steer fluid level and the gear shift.

If power steering pump is leaking your options are: replace w/new or rebuilt or have yours rebuilt.
They make stop leak for pwr steering units but it's a very temporary fix. In answer to "driving it" - it's at your own risk - if it locks up then there's possibility of an accident. I'd get it fixed and be done w/the worries. Have a reputable shop look at it and give you an estimate.

Avalon almost have the same design as benz..most likely you need to change the belt tension..that why it making that rattling noise..because the belt tension it weak..and check all the pulley while changing you belt good luck

Probably your power steering pump is going out or your power steering hose.

that would be automatic transition fluid
