Is it full of oil? Lifters will pump down if the engine is low on oil or the pickup screen is clogged.

in the rear fender well above the tire between the rear door and the tire.

there are little plastic air lines at the side of the rear struts that sometimes leak or come off occasionally.you can see them just behind the top of the rear tires if thats not it check the rest of the air lines for leaks ..If you dont see any chec the little arm thats on the ride height sensor on the passenger side lower control arm at the rear to see if it has become un attached. if thats not it you may have a leaky airbag on the strut.. hope this helps..good luck

It is called your Dynaride...it is a pump that supplies air to the rear shocks to keep the vehicle level. Makes sure that there isn't any leaks at the rear shocks, but for the most part this is normal.

call o'reillys

it is a small compressor for the ride control it pumps air to shocks individually to maintain a stable smooth ride unnecessary but good to have

the rattleing was the pump dying probably. find the leak whether a hose or the pump. replace and see if it works fine.
