That high-pitched whine while driving is much more suggestive of a problem with something spinning faster at higher speeds:
* Transmission: A failing transmission can produce high-pitched whining noises, especially under load (when accelerating).
* Differential: Similar to a transmission, a problem in the differential (the gears that transfer power to the rear wheels) can also cause whining. This is more likely if the noise changes with acceleration or turning.
* Power Steering Pump: While less likely to sound *exactly* like a jet engine, a failing power steering pump can produce a high-pitched whine, often more noticeable when turning the steering wheel but potentially audible at higher speeds.
* Alternator: A failing alternator can make a high-pitched whine, especially under load.
To diagnose the problem:
1. Listen carefully: Try to pinpoint where the noise is coming from. Is it coming from the front or rear of the car? Does it change with acceleration, deceleration, or turning?
2. Check fluid levels: Check your transmission fluid, differential fluid, and power steering fluid levels. Low fluid levels can exacerbate existing problems and lead to noise.
3. Professional inspection: Given the description, it's best to take your Firebird to a qualified mechanic. They have the tools and experience to diagnose the issue accurately and safely. Attempting to fix this yourself without proper knowledge could lead to further damage or injury.
Ignoring the problem could lead to more significant and expensive repairs down the line. Get it checked out promptly.
