Re: [alfa] Mystery squeak

[Bernie Bennett <bennetts77833@xxxxxxxxxxxxx>]

Scott:

"Turning the [steering] wheel increases the volume." Then the 'front' 
wheels / brakes would probably be a good place to start. Wheel bearings 
are a probability, have you tested each front wheel bearing for play by 
squatting with your body facing  the wheel and gripping the top of the 
tyre on each front wheel and attempted to pull it back and forth.

If the wheel wobbles just a little--your wheel bearing is loose, you can 
check it, pack it and tighten it to specs. If it wobbles a lot and it 
has begun to disintegrate.

No wobble? Loose brake caliper, sticking piston in caliper.

Sound not really a squeak; but a scraping sound, well since it goes away 
when you press the brake pedal, not a stone or pebble or other hard item 
caught between metal shield and rotor.

Good Luck,
