Hi Jim, Squeaky sounds in the rear of a 2000 Toyota Celica GT with 158,000 miles could be caused by several factors, including worn suspension components, worn bushings, and loose or worn exhaust components. Replacing the rear sway bar links may help reduce the noise if the links are worn or damaged. However, it is not a guarantee that it will solve the problem. It is recommended to have a professional mechanic inspect the rear suspension and exhaust components for any wear or damage. A visual inspection and a road test can also help determine the source of the noise. If the mechanic finds that the rear sway bar links are worn or damaged, replacing them can help improve the stability of the rear suspension and reduce the noise.

For the price and ease of replacement, I would change them out. It may or mayor solve the problem of the squeak, but if you have all the other options? Also check to see if bushings need to be replaced, or if they have been, if replaced with polys that weren’t greased enough.

Yeah it will work when you change the shocks, struts, and sway bars
