Unhappy Need help with diagnosis of load squealing and rough turning

Hi, i drive a 1992 525i and while i was driving last night i heard a strange pop noise. Then my car started to make a weird squealing noise that got loader when i gave it gas. Also it got very hard to turn the steering wheel. I think it may have to do something with the power steering pump but im uncertain. Please help if you have any idea what the problem can be. Thank you.

Welcome to the Fest.

It sounds like something is awry with your serpentine belt, i.e. it likely broke and part of it got caught in one of the rotating assemblies and is causing it to squeal. Raise the hood and take a look.

If the belt broke, make sure to check all of the rotating components such as the water pump. alternator, pulleys, etc. to make sure that they all spin freely. If so, replace the belt and you should be fine.

Then the tensioner portion of the tensioner pulley is likely shot. They're not terribly expensive or difficult to replace.

If it breaks upgrade it. I had the tensioner go on me, which release the belt which shattered the w/p pulley etc. etc.

I got one of these and never looked back. It bolts right in. and when the little hydraulic goes, thats all you replace, rather than the entire tensioner. Worth every cent.

Just to add my 2 cents: I was surprised at how little power steering fluid needs to be lost to compromise the steering.
My son's car had a small leak which we finally fixed by replacing a hose. They are expensive but safety first.
The steering would feel tight when the fluid was only a fraction low in the reservoir.
There were also leaks at the hoses under the reservoir which just needed new clamps.

I checked the power steering fluid and there was no leaks. I took both belts off and put new ones on , but the serpentine belt is still loose. So I figured that it must be the belt tensioner . Once i get enough cash ill go out and buy one.
