Brushless motor noise!

[Tear101]

Afternoon all, took my slash out for a bash on a bmx track that is a very fine gravel track! It was a bit damp so the truck got plastered(grit got in and destroyed a wheel bearing) so I gave her a quick clean off and left it. Took it out yesterday and it was make a lot of noise almost like a whistling type noise, stripped the clutch out to eliminate all the trans and wheel bearings and ran the motor. The noise is definitely coming from the motor and it's a real dry type of noise! Could the grit have got in the motor? Do people oil the bearings in Brushless motors or is it a case of its on its way out?

It's a hobbywing wp-sc8 combo!

Striped the motor and found out the front bearing has got grit in it or has just decided to start breaking up. Found one the same spec on e bay so will order one and replace it.

Does it have a slipper - might be that?
