I am hearing bearing noises in My '63 +4-4Str. It has a BTR axle sourced new about 50,000 miles ago. I checked the front wheel bearings and U joints. Sort of sounds like an aggressive tire tread. Alignment is OK. Only noise when wheels are turning. Takes about a half a mile for the noise to start and then gets louder. After about 5 miles the noise gets as loud as it is going to get. Any experience/ideas on how I can confirm if it is a rear wheel bearing.
