It might be a long shot, but I had a similar problem many years ago with a really annoying squeaky kind of rattly noise from the rear of my Stag. I chased this noise for ages till I found the brake drum was binding slightly on the brake shoes because whoever re-built the rear hubs before my ownership, must have deformed the flange slightly when pressing the locking taper stub axle out (these are fiercely tight)so had it machined flat again, thereby reducing the thickness resulting in the brake drum effectively going too far towards the hub....I procured another hub with original thickness flange and problem solved. I estimate the machined flange was about half the thickness of original. .... Good luck with it. -- *[phone removed]*

Ronanddenise M.: The noise you describe of a an intermittent rubbing from the wheels ( back ones I assume) is probably from the brake shoes on the drums not releasing correctly. If the noise disappears when braking and returns after the brakes are released I would say it is the probable cause. The cause is the brake calipers not functioning correctly or the brake shoes being pulled slightly out of alignment through poor spring retention, dust and dirt. This often happens when the car is not used very often. I found the best way to cure it is by applying chocks to the front wheels, jacking the rear wheels up (both or one at a time) and releasing the hand brake and turning the drums around by hand. Half a turn will indicate if it is a brake shoe or caliper problem. It could also be a poorly adjusted hand brake. I would take the drums off and ensure all dust and dirt is removed and would give the brake shoes a gentle to moderate tap with a rubber mallet at both ends of the shoe.. Another problem that could be the cause is a loose outer drive shaft gaiter that sometimes spins around. Fairfield Motors should have checked the above as the first probable and obvious cause.
