Another squeal noise

[Pyral]

I did my water pump a over a week ago and I have another squeal I think is coming from a pulley. This noise is not high pitched like the first time. When driving I notice this squeal happens when the engine is in gear or when I rev in neutral.

When the clutch is in or I'm idling in neutral the noise stops. Is this normal for this sort of belt noise?

Another problem is with my power steering belt, I've already adjusted it twice. Now I can turn the wheels 95% with no noise or loss of power assist, but when I have the wheel turned maximum to either side the belt will make a very loud squeal. Does this mean I have to tighten the tensioner more?

I found the problem but I don't know what to do about it. When I turn the wheel to the max, the pully nut stops spinning. Look at the 7th second of this video.

Seems like the belt is not tight enough. The belt is slipping at full lock due to high pressure.

It didn't make that noise before I changed the belt. I read there's a bypass valve to stop the pressure from building too much.

Am I at the point where it's tight enough to turn lock to lock but too loose for the bypass valve to open before the belt starts slipping over the stationary pulley?

Here's a video of it happening

It's almost as if the ps pump is stalling out? That is odd for sure.

I dont understand it. Could it be the pressure relief valve?

Ok.. On this one... Take the belt off and see if the pump can turn freely without hitting resistance. Turn it like thirty times or so As you maybe rebuilding your power steering pump as its looking like a bearing is freezing causing the belt to slip on the pulley then come loose again. That is not a loose belt on a pulley we are seeing. That looks to me like the shaft is seizing and releasing.. :-(

If it were the bearing going bad why wouldn't it be slipping all the time instead of only doing it at full lock?

Possible could have one of those pieces metal in the wheel sliding out. Regardless if his shaft is sticking, his pump will be have to be replaced or rebuilt. As the pump could have internal damage?

My right angle die grinder will do that. You put a pair of plyers on it and turned it would release again because the bearing race is badly warn. I am surprised though it not leaking out the shaft though if bearings bad.

By turning it by hand he should be able to feel if the pump has internal problems. Maybe he determine the exact issue.

This only started after I replaced the belt, so it’s either a huge coincidence that it started just after or it’s related to what I did.

And this stopped happening after I did a 300 mile drive. I did nothing and last night I was entering a parking spot and I turned the wheel all the way and it didn’t make the noise.

On another forum someone said they had the same problem and replacing the fan clutch fixed it.

If I do need a new pump are there rebuild kits that come with the seals and bearings? Rock auto has a few but I can’t find anyone who used one.

Another way to test it is to spray water on the pulley while reproducing the noise, if it becomes silent the belt tension is the problem.

About the tensioner pulleys, can I replace the bearings or should I buy a whole new one?
