Screeching wheel noise

[willisnz]

Is a rock stuck somehwere or has something failed? Driver's side front wheel.

 

 

Wife thinks it started while she was driving around.

 

Jacked it up and tried to wobble the wheel and it seems fine. Anything else I should check? Pull the calliper off?

Eww...

Worth getting the caliper off to narrow it down to braking or something further in. Can you shake he caliper at all? Had a caliper bolt work it’s way out on an old car which let it flex just enough to always rub on the rotor. Didn’t sound quite that screechy though.

That sounds like a stone or something is caught somewhere between the caliper/rotor and backing plate.

Sadly, to make it easiest, the wheel will have to come off.

And be great full you're only dealing with STEEL calipers. Not alloy Brembos etc. Low chance of stripping threads

In the process of moving the car from the street to the drive way it stopped,phew.

 

Funny as my wife says she drove for about 1km with it doing this...maybe reversing with full wheel lock was the trick!

Could also be a wheel bearing,

I had this in a 2000 Forester, wheel wasn't wobbly but one side of the bearing was turning on the hub.

Sounds like something scratching on the backing plate behind the rotor. If you're curious you could pull it apart and you'll probably see the scratches on the plate.

Will take it for a spin round the block this avo to check it is definitely gone.

 

Due for a service so will have a poke around when AJ has it on the hoists.
