The sounds also changes slightly when I turn the wheel. It may be unrelated but it also makes similar sounds while in reverse.

Do you
have the same problem?

It might be a powersteering pump. Have a pro look at it they normally don't charge for an opinion.

Thank you for such a quick reply. What problems could I face if the power steering fails completely?

I've heard that it could effect my braking power or cause brake failure. Is that true?

It wold only do that if you had a hydraulic unit for a braek booster and I don't think in 91 that was done yet. If you have a hydraulic instead of vacuum brake booster then it would if hte pump failed.
