Hey guys, I've got a 2000 blazer 4.3l. Weird sound coming from front end I have no idea what it is. I've replaced the ujoints, they're good, I've checked the wheel bearings and there's no play. Transmission oil is good, tires were just balanced (just got winter tires put on)

The sound starts around 40kmh, and gets worse the faster I go. It is not dependent on RPMs it is affected by my speed only. It makes a 'whining" sound while I'm getting up to speed and turns into a grinding. When I brake it sounds like a low moaning.

My next thought is maybe warped rotors..?

Does anybody have any experience or thoughts on this?

Thank you

When did the ABS light start coming on? I'm guessing front hub because of the ABS light.

I've had a hub start going out, sounded like a jet was flying over the truck but still had no play when the tire off the ground with ABS light on.

Most (all but one) of the hub issues I've had over the years, the ABS light is always the first indication.

 

Thanks for the reply

ABS light has been on for quite a while now, unplugged the fuse because ABS was terrible in the snow.

I did check the wheel bearings, checked top and bottom no play at all really. How else could I diagnose the hubs before replacing them?

Any other ideas? Me and my buddies are baffled :/

 

found out it was the rear diff, if anybody was wondering

 

Was it a bearing ?....if so do you know what bearing it was ?

 

I was wondering. Thanks.
