I've had this clicking/squeeking noise from the rear left side for a little while.
First I thought it was the rear side window mechanism that was worn, but no.
Then I suspected the rear seat, (found that the top was not fastened), but no.
Today the clicking/squeeking noise was worse than ever.
And as I drove along I started suspecting the rear schock.
Jacked up the car and to my horror I noticed that the rear shock mount had failed as the front fastner nut for the top bearing came into sight as the loose bearing tilted down into the wheelwell.
The loose bearing is what made the noise.
Now the top mount has not failed totally, only the metal between the big center hole where the bearing is and the small hole that is the front bearing mount.
The rear mount is still intact and the shock is still in it's place.
Might be a thing to consider reinforcing guys.
Dont think this will be an expensive fix, the damage is small.
But I'm going to reinforce both my top mounts for sure.
