Greetings!
I have a 2002 Avalanche Z66 2wd with 170K miles. No bearings have been replaced.
But I`m starting to get some of the symptoms that yall are describing!
1) Every now and again my ABS/BRAKE light comes on. I turn of the truck and turn it back on the lights are gone. (intermittent problem)
2) While my truck is off the ground and I spin the front wheels (both), they spin with ease and very smooth but I hear a ,"tink, tink, tink, tink, tink, tink" noise. Sounds like little metal pins falling. Is that a sign of the bearings going bad?
3) Cruising about 10-20 MPH I can hear what (to me) sounds like metal to metal grinding "crick, crick, crick,crick". Its very faint. I CANT TELL IF ITS COMING FROM THE FRONT OR THE REAR
. More noticeable when LIGHTLY applying the brakes. But she rides smooth and I don't hear anything abnormal when driving at regular speeds. I drive dayley about 60 miles on the interstate. 75-80MPH
I was prepared to replace both the rear bearings and seals - but now i`m second guessing myself because everyone is having issues with the front bearings!
Any recommendations?
Whats the best way to figure out which bearings are going bad?
