Let us know what the repair was when you know.

 

I had a similar sound on my truck, minus the grinding. I was the right front wheel bearing. Also, the Bilstiens were supplied with the premium suspension package, RPO code ZW7.

 

It turns out it was the passenger side wheel bearing. I would have attempted to fix itmyself but was unsure if it was the actual wheel bearing or the CV axle so I let my mechanic diagnose the problem and fix it. Thanks for the info on towing the Blazer, the tow truck driver was ready to hook on to it and tow with the rear wheels on the ground till I basically had to tell him use the dollies or don't tow it at all. Next on the list is the fuel level sensor to fix and I should be good. The wheel bearing I replaced it with cost 300 Canadian bucks but it's guaranteed for life. All said this repair cost me 370 dollars.That's the difference between Can and the US parts are way more expensive up here. Here's another example, an x-pipe for my Mustang is anywhere from 300-450 US but in Canada I couldn't find it for less than 650. Anyway thanks for the info and tips and I've now found another forum that I'll use frequently.

 

Glad you got it fixed.
