More than likely you have a constant velocity joint going bad, these are on the end of the drive axles that connect to the inside of the front wheels. Sometimes if they are not worn badly the joints can be repacked with grease and new boots installed, but usually it's better to replace them.
When you turn the steering wheel and hear a popping noise, it could be due to the power steering pump and a sticking valve so there is not enough hydraulic pressure. It could be caused by the steering linkage going out or low power steering fluid.
The wheel has a whole in it.
I heard it was an intermediate steering shaft and cost around 130.00 dollars
The gas making the popping noise is hydrogen.
Inspect the steering components, suspension, and brakes.
i replace power steering pump and it still making noise, what do i need to do next, is there adjustment?
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.
The pockets of air are being compressed making a popping noise.
Unfortunately the power steering unit is on the way out.
The u-join is probly going out
A front popping on the left of a 98 Blazer could be the brakes, steering, or wheel bearing. Check all three to find the cause.
if the noise is a high pitched squealing noise, the belt is slipping....if the noise is a whine or growling noise, the pump is low on fluid or the pump is bad
