Shocks

Not sure if this is the correct thread...

I am wondering if my shocks are bad.

2004 canyon z71 crew 3.5l 75,000mi

When I drive over dips in the road or railroad tracks that are raised up on a little hill my suspension will travel quite a bit. I can hear what I believe to be air coming out of what I think might be the shocks(only thing that I think can make that type of noise in the truck).

When I push up and down on the bumpers I don't seem to get any excessive travel.

Could I have bad shocks?

I am not sure if they are original or if they have been replaced.

Any help would be appreciated

They most definitely could be shot at 75,000 miles. Usually you start to think about it around 50,000.

Have a shop check out your tires. If they show signs of cupping then the shock is no longer strong enough to keep the tire in contact with the road. I suggest a shop (like alignment or front end shop) because they have a better eye for that type of thing.

If you use your truck as a DD, there are other shock options available that are more like stock, less stiff then a 5000. No need to run a stiff shock if you have light tires/wheels and use it for daily commuting.

I haven't noticed any signs of cupping.
I do use the truck as a daily driver but I also take it hunting and Hunting and occasionally haul crap in the bed.
I also plan on getting a hitch and a small boat pretty soon too

Could that air sound be from bad shocks? I didn't see any staining on the shock itself from oil

I'm just not sure if the previous owner replaced them

the rancho 5000's arent really all that bad for a DD.

When I had to replace one of my OEM ones due to leaking I replaced them with Gabriel from Autozone. But then again, I was just looking for a stock replacement. But the lifetime warranty can't be beat.

Just be glad you don't have coil fronts. Your shocks are cheap compared to replacement struts. :anger:

I don't know if the stock shocks are gas or hydraulic. Hydraulic leaking shocks will show leakage of the hydraulic oil. Gas shocks may make the sound of air. I haven't noticed cupping of my tires but when one of the shop guys showed me I was more able to see it. It's not always very distinguishable. In my case it was a previous truck and different tires.

I will hopefully install my shocks this weekend. I've had them for about a month now. :(

Stock shocks are gas/hydraulic. They use oil to provide the damping action and pressurized gas to keep the oil from foaming from the shock working.

As for the cupping, try lifting the tire in question and spinning it while lightly running your hand on it (inspect first to be sure no glass/stones/etc that can cut you are embedded in the tread). Your hand can feel differences better than your eye can see them.
