post icon Rear wheel/axle noise Sign In

1995 VW Golf III - 2.0 liter 4 cyl. with 98,288 miles.
Loud, dull hum coming from rear wheels that is proportional to speed (i.e. speeds up and slows down with tire rotation while driving - almost sounds like running on knobby tires). Tires are new, no uneven wear and/or cupping. No sounds of grinding and/or squeal as in metal to metal. Any thoughts on what this could be? Emergency brake issue? Grease/bearing issue? Please let me know your thoughts. Thanks.

That's near "textbook" syptoms for a bad wheel bearing. Hoisting that wheel and spinning would help nail down that diagnosis. Compare it to the other side. Bearings by themselves should be SILENT - some brake parts may make a slight sound in testing. You really know when the old one is in your hands and spun with no other components to confuse the issue. This should be a packable inner-outer style and you would see the "galling" (small dimples) on the race of bad one(s)

Note: Not always, but sometimes the noise carries and can be the opposite side from what you think from driving the car. Should be a very doable repair for most DIYers as this is listed as an "inner and outer" greasable type - that similar to the way trailer axle bearings are done. Follow instructions carefully on "race" removal and installation, initial setting of it and final spot where you leave it. New grease seals inspect and pack all bearings(four - two per axle) would be advised too,
