Usual Problems of the Lexus ES300 Splash Shield
Aside from covering up the underbelly of your car and making your wheel well much more appealing, your Lexus ES300 splash shield also protects very important components of the engine from rocks and other debris. However, this typically plastic component can eventually become worn out, and the important wiring harnesses and other parts that it protects can become exposed to all sorts of damage. Here are some of the most common Lexus ES300 splash shield problems:
Splash shield getting cracked
Constant exposure to the heat from your tires and the cold rain, mud, or snow can eventually make your splash shield brittle and prone to cracking. Small cracks in the splash shield that are only about an inch or two in length can be easily repaired using epoxy body filler. However if your splash shield has sustained some massive damage, then you're much better off getting a brand new one instead.
Splash shield rubbing on tires
When a visual inspection of your ES300's splash shield shows that certain portions of the component have been melted off, then your tires are probably coming in contact with your splash shield. Listen for squeaky noises from beneath your fenders whenever you're making a sharp turn since these noises usually point to your splash shield being melted off by your hot tires. You can get a new splash shield to replace your melted one. However, to ensure that this problem doesn't happen again, you need to trim or shape your splash shield to make sure that they won't rub on your tires any longer.
Splash shield falling off
If you hear a scraping sound from your wheel wells while you're cruising through the highway, then you might want to take a look at your car's splash shield. A broken, loose, or lost fastener clip, screw, or bolt is the most common reason of a splash shield that is falling off, so make sure that you check if all the mounting clips on your splash shield are still intact. In case any of the clips are broken or missing, you will have to get some replacements from your local hardware store.
