bearings old tires shock observers steering wheel
Your Mazda Protege might make rattling noises when parked because of a loose or damaged muffler or even body panels that are loose. It might also make a rattling noise because of a damaged motor mount.
Its either loose or breaking down internally.
yes
lifters are beginning to go. timing chain (if vehicle is equiped) may be coming loose. and or exhaust pieces are loose.
Possibly: A faulty shock - incorrect installation - a mounting bolt not tightened sufficiently - something touching the shock/strut and vibrating against it. Take it back and complain.
tie rod.... your tie rod rubber wore out...needs anew rubber or new tie rod
no oil
The rattling you are asking about turned out on my 320 to be the catalytic converter breaking up internally.
I would suggest these could be symptoms of a failing belt tensioner.See "Related Questions" below for more
Is your oil level?
It may me that your brake is on.
