annoying squeal/squeak on a 06 plate Gti

<< < (3/3)

Despite getting rid of my main loud squeal (the PCV valve), it seems I have a faint background squeal somewhere from the drive train, the curse of listening out for things when you have fixed them to uncover another problem! 

Once the car has a few miles on it ~10 you start to hear a squeal at 30-50mph, much more than 50 and there is too much road noise to hear it and generally only when the windows are down.

Touching the brakes doesn't get rid of it, putting it into neutral doesn't change it so im a bit stumped as to what to do.

The only thing I can think of is that I recently did the driver side outer CV boot so the whole shaft has been off, has anyone had any wheel bearing issues after undoing the hubnut?  can wheel bearings squeal like this?

I never had noise after doing my CV.

Did you 100% remove, clean and replace with new grease? How long was the boot split? Maybe the actual joint started to wear down if there was no grease left and now it's grinding.

it started to crack on the small end of the boot so it didn't chuck all the grease into the arch and get much in it.

Took the whole thing apart, cleaned it all up with degreaser and took the ball bearings out and regreased everything. 

Its more of a squeal than a metal grinding sound
