I have a 2000 Chevy Blazer that has been in the shop at least 5 times now. The problem is that periodically it starts making a very loud siren, helicopter type noise which gets louder at speeds below 50 mph. The auto tech people say they cannot determine what it is unless they can hear the noise, etc. So of course after I get it to the shop it doesn't do it. It sounds like it's coming from the front right side. They have checked the wheel bearings/hub and say that they are not bad. Most recently they replaced the radiator fan clutch assembly because I thought that might be the problem. But the noise is back and louder then before, so that was obviously not the problem. I have had new tires put on just recently and it drove fine for about a week, no noises, etc. Then suddenly out of the blue, they are back again and seem to be lasting longer than before.
It seems to be worse when slowing down at speeds of between 25 mph and 40 mph. And there is just a slight vibration in the steering wheel, but not that bad. I am about to lose my mind trying to figure out what this could be. I'm afraid to drive it because I think it may be causing more damage to whatever is going bad. It is really discouraging because I am having to research what the problem could be, when it seems that should be the auto shop's job.
Any help would be greatly appreciated. Thanks!
