the body pan underneath has a plastic or hard rubber mud or dirt guard. the lip underneath the drivers side is loose and is flapping making a noise. can i drill two holes for sheet or body screws through the guard lip and the body pan and seal to stop this.
mud or dirt protector loose on 2008 Lexus RX350
These kinds of repairs need to be inspected carefully. What your asking is very possible, but one would need to look at it to make the determination as to the best approach for securing the guard. Be very careful you don't run the new screws into anything important.
Loose flap is a common problem for the RX 350.
