Quick Struts & Sway Bar Bushing and Links

[Ben5563]

Hi,

Since last week, as I have been going over speed bumps, I hear a sort of clunk/creak coming from the rear part of my car. I took it to the shop and they said I need new quick struts, sway bar bushing kit (rear), and sway bar link (rear). This (plus labor and wheel alignment) costs $2000 so I wanted to see if anyone has had a similar issue and knows if this is an urgent matter or more of a touch-up type of repair.

Thanks.
