I live in southern california, Los Angeles County.

1. How do you check for belt tensioner? do I press the belt to see if it is tie enough? I have pushed down the front end hard to test the shock and the car bounced back instantly without excess swing.

2. I don't hear any funny noise from front end, just the tire noise because I have plus size tire installed. (225/45zr17)

3. LCA Bushing crack issue, is it easy to replace? how about the parts, expensive? any dangerous if i don't replace it for a while (1-2 month?)

4. as for the door issue, when I open the door wide, I can hear a click sound, is it the CK straps failure?

thanks
