How to tell if you need to replace your Shocks!

When i look at my shocks, i can't see any tears and wears or even leaks but if I run over an object, I feel like I need new shocks.
What other ways can to recognize a bad shock?

 

Try to avoid running over "objects"?!?

After driving the truck for a few hours go put your hand on all the shock bodies and see if there is a temperature difference. Cold means not working. Warm working.
Shocks aren't expensive. If in doubt just replace

 

Just replace them. The roads being so horrible means shocks don’t last. New ones will be an improvement, regardless.

I’d thoroughly research them and not just buy whatever the counter guy tells you.

 

Be sure and replace your cab shocks, too. They make as big of a difference as the suspension’s shocks.

 

Cheap, easy to replace, can do it yourself in no time with couple wrenches. I change mine every 2 years or so, maybe 180,000 miles. I like gabriel fleet line.

 

Definitely replacing every year or two. Cheap and easy to do, and in my opinion prevents wear and tear on other parts.

 

Carb shocks? That might be it. Where's it located?

 

Ummm, under the cab.

You need to replace all your shocks as a set.

 

Yeah I figure that out. Because sometimes when I get out the truck, I hear some hissing sound on and off.

 

Temp gun, compair temps. Handy to walk around and check hub temps also when you first pull in from the road.
