Hello
Welcome to FixYa
there is a u joint to be replaced on your steering shaft just after the steering shaft
open the hood look down to the steering shaft you will see a small u joint very common to go bad most auto parts stores carry the part

Is the engine also running poor such as tries to stall or the RPM is high? Is there an unusual suction type sound? Check the vacum hose to the brake booster, if loose, cracked or a hole in it.
This is about a 1/2" diameter hose and goes to the booster from the engine for power brake assist.

i dont know if this makes sense, if its the big clip, you push in the cylinder and twist until the clipp comes off

You can drive on those struts untill it has no sping, and even then it is just dangerous because of bad handling. If it is you struts, then your car should bounce up and down if you tap the brakes, because the gas seal is leaking.
Struts are very easy to replace. The only special tool is a spring compressor, but it is easy to use, and you may be able to borrow one at an auto parts store like the AutoZone. Just a couple bolts at the top and bottom, and it comes right out. They cost less than $100.
If it doesn't bounce...it could be your half-shaft. Does it click when you make a turn backing up?

Testimonial: "Thanks Captain, I'm worried now that the noise is not coming from the struts because the car does not bounce. What is a Half Shaft? "

It is likely both your track bar and the lack of a steering gear box stabilizer. The bushings on your stock track bar can be replaced with polyeurethane or metal bushings which will help curb the problem.
The steering stabilizer attaches to your steering gear box and your frame allowing the steering to be more stable. I have put both on my truck and it drives like a caddy now as a result. If I had to choose between the two items, my money would go to the steering stabilizer first. I believe I bought mine here:

Hope this helps
