First, get new shocks and struts...on that vehicle, not entirely sure, but probably struts in front and back, no shocks. Check for coil springs in rear. If rear springs are coil, then struts. If rear springs are leaf, then shocks. While you're at the parts store, rent or borrow a coil spring compression tool. You'll need to compress the coil springs to remove/reinstall new struts. Other than the compression tool, standard garage mechanics tools will do the job.
A coil spring is primarily subjected to two forces: compression and tension. Compression force occurs when the spring is being pushed or compressed, while tension force occurs when the spring is being pulled or extended. These forces cause the spring to deform and store potential energy.
There are 4 struts, They are not shocks.. They are called "coil over's". Meaning coil spring over strut. You will need a coil spring compressor to replace them yourself. Rent one at autozone.
How long does it take to change a front coil spring on a Peugeot 206
No , unless the spring is damaged
yes they will work
Lesabres only have air suspension in the rear, they will be a combination of air shocks with a coil spring on the lower control arm.
The springs in the rear support the weight of the car, and give it a smooth ride along with the shocks.
This is a strut suspension. You have to remove the complete strut. Then you will need a spring compressor to release the coil spring. From there the shock can be changed. It would be cheaper to take the car to someone and have it done as the tool's needed will cost you.
you dont need to remove coil springs to change shocks just remove 2 bolts on the bottom of the lower control arm and 1 at the top the shock goes up thru the center of the controlarm and the coil spring
Take it to a garage
Coilover shocks are a type of suspension system that combines a coil spring and shock absorber into one unit. They are adjustable, allowing for modifications to the vehicle's ride height and damping characteristics. Coilover shocks are popular in racing and performance applications due to their versatility and ability to improve handling.
