Jeep 2002- help!
I recently bought a used Jeep Liberty 2002 from FB market and it has a few things that might be off? I don't have enough mechanical experience to understand certain parts of my car and theres already a few things it needs; window shocks for the trunk, a new latch/motor for the trunk door, and most likely a fuse bcs the sun roof won't open. Today I saw an orange spongey looking piece by my tire that crumbles if you grab it, google says its a suspension bump and that it needs to be replaced but I'm broke and if it doesn't have to happen now I'd like to wait. I've noticed that sometimes when I turn the steering wheel it squeaks?? When it first happened I assumed the leather was coming up and rubbing the plastic but when I took a closer look it was definitely something behind the dash plastic that was making the noise. (maybe just needs WD40?) My last thing is that there is a controllable bass in the car but when I turn it up the right speaker makes a kind of rattling noise and I'm not sure how to see if anything is broken/loose. The speaker is on top of the dash.
Here's the orange sponge
