Technical squeeling noise

[Karletto]

it starts squeeling somewhere front and always after xy min of driving. it stops squeeling for few moments when i turn the steering wheel left/ right or when i press on brakes. the noise gets lowder and lowder after few months. what's squeeling??

If it goes away when you only lightly touch the brakes or slightly turn the steering wheel it could be could be front disc brake pads.

Check they are ok, perhaps remove them and get a little copperslip and put a small smear or the back of the pad. The surface that goes towards the piston, not the surface that goes towards the rotor!! (disc)

The symptoms sounds like a slipping power steering belt - but that's unlikely as no Uno came with power steering (as far as I know). rawill's advice is very good. Also, check that the driveshaft nuts are tight (if not, the slack in the wheel bearings could lead to noise from the brakes in the way that rawill described).

Other sources of squealing from the engine bay:

• Alternator belt slipping
  
• Cambelt tensioner worn
  
• Clutch release bearing worn

By a process of elimination you will find the cause of your problem
