Rear Upper Strut Mount Removal?
 

I made a post about a noise i get from rear passenger side wheel area when going over bumps.
I was guessing upper strut mounts and so did the shop i took it too.

I want to remove the strut assemblys and check the mount. A couple questions though...

1. Does the mount require the spring to be removed?
2. If i replace 1 side, should i do both?
3. If i replace them, would i need to get a rear allignment?

Thanks.
