Your car made a popping noise then you lost all power steering what happened?
Was there any fluid leakage? if so, may have blown a high pressure line, if not, the bearings in your pump may have seized, undo the belt off the power steering pump, can you rotate the pulley by hand on the pump? If not, likely the bearings seized. If you can rotate it without a herculean effort, check your lines and fittings for any wear or loose connections. I'm assuming the popping noise originated from under the hood.
If your power steering pump makes a whining noise as you turn your steering wheel your power steering fluid reservoir is probably empty. The noise is caused when your power steering pump tries to pump fluid that is not there. This indicates that you probably have a leak somewhere in your power steering fluid lines. You can either try to find the leak or simply replace the power steering fluid every so often.
If you mean "what" is making noise when you turn the steering wheel? It usaually means you need power steering fluid. If you run too long without power steering fluid it will make your power steering go out. If it is making a shuttering noise when you take sharp turns. Your rear differential may need to be serviced. I would have is burnished.
If it is a whining noise, the vehicle is low on steering fluid or the power steering pump may be going bad. If it is a clicking noise, the CV joints may be going bad. NOPE a Saturn vue has electric power steering and no pawer steering pumpA Saturn vue has 4 stabilizer links and they are made of plastic Moog makes metal replacements for the front but the rear still come from the dealer…
If the power steering pump is making a whiny noise on a Pontiac Grand Prix, the way to tell if this noise is from the pump or another source is to turn the steering wheel. If it turns hard, the problem might be with the pump. If the belt quiets down after a drop or two of dish soap is placed on the belt, then it was just the belt causing the noise.
