No.
New struts on a 2008 Dodge Caliber may make noise due to improper installation, such as not tightening bolts to the correct torque specifications or failing to align components properly. It's also possible that the struts themselves are defective or that other suspension components, like sway bar links or bushings, are worn and causing noise. Additionally, if the struts are not properly lubricated or if there is air trapped in the strut assembly, this can lead to noise during operation.
Yes, it is generally recommended to replace the strut mounts when changing the struts. Strut mounts can wear out over time and may contribute to noise, vibration, and poor handling if not replaced. Installing new mounts along with the struts ensures that the entire assembly functions optimally and can help extend the lifespan of the new struts.
The strut mounts take some time to settle in. Resulting in a squeak for some distance.
Sounds like you need new struts.
you need new struts
You might need to get new shocks/struts. If they are decently new it might be a loose bolt or worn out brushing. (rubber things that surround the bolt on struts)
A bad wheel bearing
Springs, not struts set the height.
Answerif it's a whining noise you may need to check your power steering fluid level. I had this same problem. And if I am thinking of the same straining noise your talking about. Mine sounded like a noise like wet rubber was rubbing hard together? is that the same sound? if it is the same sound, I had to put new front struts in my 1999 Dodge Avenger and it didnt make the sound anymore.
Coil spring boosters are only for coil springs, NOT those found on struts. Struts are engineered to function in only their original configuration and should not be modified. Look into finding new struts that will fit your application.
Might just need an old fashioned lube job. Do the easier, simpler, cheaper stuff first - struts can run into gobs of money not only for the part, but especially the labor charges.
New brake pads can squeal until the are broken in. Some cheaper pads make noise all of the time. If the pads continue to make noise there are chemicals that can be put on the pads to quiet the noise.
