Roaring noise

Sonny · Apr 18, 2017

Took my '70 b body to work today and on the highway heard a rythmic roaring noise from the rear. Goes away when l let off the gas. Rear end? Going to have the gear oil checked at lunch but there are no obvious leaks.

Make sure your U joint or pinoin yoke isn't loose

Mine does that too on the highway. I've always thought it was the 3.91's or maybe a driveshaft slightly out of balance, but I'm not sure.

Could also possibly be an axle bearing. Had it happen on my '65 Monaco. Same symptoms.

Axle bearing sounds like that, though maybe more constant than rhythmic. Kinda like you suddenly have a set of snow tires.

Go to your local votech - the teacher can diagnose it for free on a lift - then if possible, take it home and do it yourself.

Usually if it gets quitell when you cost it could be a loose pinion yoke or a worn out pinion bearing
