I think the wheel bearings is worn on the right side front right wheel on my 1999 Blazer ZR2.
It can also be a CV joint but i that was the case you would hear the noise more when you are doing a tight turn which is not the case with my car.

I guess this is because i have never used the Blazer much at wintertime and because og that i usually drive with rear wheel drive 99,9 percent of the time.
But this winter i have used the Blazer every day and in 4 wheel drive mode all winter.

Since i have no idea i will ask here.
Any here on the forum that knows if a 1999 Blazer ZR2 use use "special" wheel bearing-hub`s or can you use regular 1999 Blazer 4WD wheel bearing-hub`s?

This is for the front wheels

Here is a couple of pictures of the wheel bearing/HUB from Rock Auto

Hi, I changed mine recently on my zr2 no compatibility problem. only the CV axle changes size with the ZR-2.
