Buzzing Under My Is

[James]

I was out in the IS today and suddenly there is this horrid buzzing from under the drivers side. Stopped at the side of the road and looked underneath it (how embassing to be seen peering under a Lexus...) and found some of the plastic under tray flapping around. It turns out that the plactic has broken up around the bolts that should hold it on. It's only 2! Anybody else had bits fall off?

By the way, while I was under the car (on ramps at home, I'm not that skinny) I spotted a box screwed to the floor above the diff? Anybody know what's in it? Just wondering....

Yep had the same thing but sounded like i was draggin the rear bumper down the road................not hard to replace though i havnt done it yet.....just took off the offending piece.

Had a similar problem with the plastic covers breaking from the mounting bolts. If it's not that badly damaged, simply get a washer larger than the mounting hole to keep it in place.
