Knowing when to replace shocks

It may seem like a no-brainer for some of you, but I never knew how to look for worn out shocks beyond the 'bounce test' or general feel. Hopefully this helps some of you guys too.

How to tell if shocks are worn out

Scroll down to the pictures.

 

Typically, oil loss is a good sign. Or do the bounce test. Use your whole weight and bounce each corner of your vehicle. It should only bounce 1-1.5 times. Anything more is excessive.

 

I found out by the oil that wasn't supposed to be there...think I'll read your link.

 

I would probably be one of those people with tire seizures...haven't replaced the shocks yet.

 

I know there are a lot of variables involved, but aprox how long should stock shocks on an 08 (non-TRD) last? I have 46K miles and it seems like the front end is getting a little loose/bouncy on our "wonderful" Southern California Freeways.
