Like many others, I had the rattle sound since the day I drove my new vehicle off the lot. It seemed to emanate from behind the glovebox, was intermittent, and (at least for me) only manifested with car in drive and stopped (typically at a red light). This rattle was pretty dang loud and definitely annoying. Brought to dealership twice with paper print-outs from websites delineating other owner descriptions and purported fixes for this issue. Dealer said they couldn’t reproduce sound and therefore did nothing.
A Big “hats off” to Mtn40 who placed the most helpful post on this topic: where he both reproduced the tapping proving its source, then showed best way to access the area to employ a fix. ( Glove Box Rattle ).
For any others who are still enduring this tapping issue which seems to be some vibration/harmonics process causing paired hoses with metallic clamps to hit the firewall, you too may want to follow forum member Mtn40’s great lead.
I jacked up the front passenger side of the LC250 and removed tire giving good access/exposure. You’ll then need to remove a smallish plastic trim piece :
Trim piece is attached by 5 connectors which are easily removed by using forceps or similar to squeeze pins together then retract them. Come out easy and are reusable.
Once the trim piece is off you’ll see the suspect paired tubes on the left.
Shine some light on their path as they ascend, and you'll come across clamps and a connector bearing the number "57". Its directly under these connectors that abutment with the firewall occurs .
Now all thats needed is to secure buffer material between these connectors and the firewall. I used a rectangular piece of self adhesive sound deadening mat suggested by others.
Its been a couple days with my antenna out listening for the rattle and its gone. Once again LC Forum 1 : Dealership 0.
