Brobichaud Posted December 29, 2014 Report Share Posted December 29, 2014 I hear a thumping sound from the front end upon slight right turn @ 10 - 40 mph. Thumping sound disappears when going straight or turning left. Unrelated to braking. Related to wheel rotation. Rotated tires - no difference. Noted that driver's side front wheel bearing is a little sloppy. Wondering if thumping noise can be attributed to a sloppy bearing. Link to comment Share on other sites More sharing options...
winterset Posted December 29, 2014 Report Share Posted December 29, 2014 Check your axel half's - especially your left side. Look for grease sling on the frame, or a tear in the boot. Other thing of the strut rod bushings. See if you can easily kick your tire back or forward when if is suspended. but yes, if your wheel bearing has play, it can be noisy especially if the noise is happening on just rotation.

Kevin K'nine Gottlieb Posted December 29, 2014 Report Share Posted December 29, 2014 I replaced my bearings a few months back, and the symptoms I would get would be loud humming noises and grinding. All noise would go away when I turned a corner though! Link to comment Share on other sites More sharing options...
IceCold Posted January 2, 2015 Report Share Posted January 2, 2015 Your HUB BEARING is bad buddy. I had the same problem on my 05 Deville. I heard a humming noise when turning right, at that point the weight of your car transfer to the left. On a safe street, do a series of S turns by going left, then right as a NASCAR driver to warm tires. If you hear the noise when veering right, its the left hub.

Brobichaud Posted January 3, 2015 Author Report Share Posted January 3, 2015 Knew the left bearing was bad due to looseness. Ordered a bearing/hub assembly last week. UPS should deliver Monday. Crossing fingers that new bearing addresses the thumping noise. Thank you for the info! Link to comment Share on other sites More sharing options...
winterset Posted January 3, 2015 Report Share Posted January 3, 2015 I hope you got a Timken or acdelco. Those others on eBay like Detroit axel for $50 are garbage, and will only last 5000 - 10,000 if you are lucky. You should be able to buy a timken for under $100 Link to comment Share on other sites More sharing options...
