Replacing shocks - what to look out for?

[caadoptees]

I have new shocks coming (along with the window rock guards). I have no idea when the last time these were replaced. At most 14 years ago! They look like they need so I will do it.

I sure don't want to twist off a bolt or anything like that. Should I load them up with a 'liquid wrench' type of solvent first? A friend mentioned to use a torque wrench, not so much for putting them on but taking them off so you don't use too much oomph and bust it.

Best practices please?
