Yes
Cars would use shocks or struts in front but not both.
One reason a cars front end may shake is bad struts. However, it can also be other things such as a bad tire or even if an alignment is needed.
Yes. All cars have struts in the front and shocks in the rear. However, it does not have McPherson struts
The Struts are the shock absorbers that include the spring. They are commonly referred to as McPherson Struts. Most cars now have Struts on the front and rear instead of the simple shock absorbers.
Front Rotors can be warped, or bad struts. Had a 90 Camry that steered like a boat on the highway, until the struts were changed.
Some cars you can and some require 4 wheel alignment.
All cars require a front-end alignment from time to time. The parts are subject to terrific wear and tear, causing things to go awry - thus the need for an alignment.
Shocks.
A fairly quick and fast way I check struts is I put all my weight down on the hood and give it a push, if your struts are good, it will not allow the car to bounce at all, it will basically absorb the shock and your struts are okay, otherwise your car will bounce excessively and its time to change out you struts. Same procedure for you rears, except they should be coil over shocks and less complex as most cars front suspensions.
If it is out of specification the rear, yes. If it is in specification, no. Makes sense, doesn't it! Some cars have adjustable alignment angles in the rear, and do indeed call for a four-wheel alignment. On many cars, there are no rear adjustments, but the front wheels should be aligned with respect to the rear, what is properly called a thrust-angle alignment. Unfortunately, many shops are not careful with their terminology and use the term "four-wheel alignment" when they really mean "thrust-angle alignment." Even so, they usually correctly distinguish between cars that have alignable rear ends and those that don't, and price the job accordingly. As to whether your car has an alignable rear end, you'll need to refer to a shop manual to find out.
yes all cars and trucks need to get aligned at some point
They have four struts, one for each wheel. Check out Dodgeintrepid.net for a ton of info on these cars.
