Question about 1998 Cadillac DeVille
This depends on what type of noise you are hearing. A light 'hissing' noise is normal with power steering on full lock and apart from ensuring that your power steering fluid level is correct there is no action required.
However if there is an excessively loud hiss or growling from the steering under light use this can be caused by anything ranging from an airlock in the system to more serious problems with wear in the pump or a restriction in the system itself.
If you are sure the fluid level is correct and are still concerned by an excessive level of noise, it is best to have the system checked out by a specialist given the numerous possible causes of this.
A system like this is not easily serviceable unless you have a good knowledge of the workings and access to relevant specialist equipment/replacement parts.
At the end of the day steering is not something you want to take any chances with!
Hope this helps. Thanks for using FixYa.
