#19 of 21 high speed vibration by boggsy1 Sep 13, 2009 (4:00 pm)
I have an '02 avalanche. It just started moderately vibrating between 63 and 73 miles per hour. Slower is ok and faster is ok. Bought new tires in April and haven't had any problems until now. Jacked it up and nothing seems loose, tires have no bulges or defects on the outside. Alignment? Help! Replies to this message: erickpl (Sep 18, 2009 10:53 am)

Replying to: boggsy1 (Sep 13, 2009 4:00 pm) Did you get an alignment? If you lifted it, the front wheel camber will be off and will need an alignment or the outer edges of the tires will cup and you'll get vibes. -Paul
#21 of 21 Wierd Avalanche Noise by roy40 Dec 03, 2009 (9:43 am)
If I apply the brakes and stop with the wheels turned left or right (as at a 'T' intersection) there is a wierd noise like a brake dragging or a locked-up differential. It's wierd because it doesn't make the noise if the wheelsremain straight when stopped. I can then turn them and there's no noise. What gives?
