There really isn't a set interval for this. How fast your shocks wear is going to depend on the quality of the shocks you use, and what you do with your truck. If you use your truck for sitework and drive on a lot of access roads, logging trails, and the like, you'll work your shocks more than a typical highway driver would.
Basically, when the time comes to change them, you're going to feel it. Even if you have air ride on all axles, you'll feel it.
Of course, if you actually do your pre-trip (as so many steering wheel holders out here neglect to do), you'll look for obvious signs.. physical damage, fluid leakage, decompression of the shocks.
Whenever the shocks are deficient... e.g., leaking oil, damaged, excessively hot after driving.
Stand on the front and rear bumbers, and bounce the truck up and down then jump off. the truck should bounce once are twice. If it bounces more then that, replace shocks.
Who invented the Semi-truck?
If the semi truck knocked on the garbage truck, yes.
no,not truck shocks, but you can use spring helpers or you can order a lift kit for the front and for the rear you can get air shocks from your local parts supplier.
A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
Semi-articulated
8000 gallons
Yes
You don't. They use either a linkage or a hydraulic clutch.
There is no prefix in truck.
Not until the truck starts bouncing. are the shocks go to leaking.
