Vibrating noise, need some pointers..

[98LXand99LC]

On the way home from the beach yesterday I noticed a slight vibration noise coming from underneath my '99. It was a very quiet rattling noise, like maybe a heat shield. It was very quiet, I had to turn the radio and the AC off to hear it. Anyway, before I crawl under there I was hoping someone could tell me where to start and what to look for (ie. a loose nut or bracket).

So, if anyone has any experience with this please let me know...

Thanks, in advance.

It is probably the heat sheild. What I did was stick my rachet wrench into the space between the sheild peices and bend it just a bit so when it vibrates, it wont hit each other and make that annoying sound.

I had the same rattle in my '99 a few months back. It would rattle when I accelerated from a stop. Very faint, but annoying. It turned out to be a heat shield. I don't have the tools or the time to fix that type of stuff myself, so I took it to the dealer. Parts cost about $125. The labor was rolled in with a bunch of other maintenance type items, so I don't know how much it cost total. The rattle stopped immediately though.

Cool, thanks guys. I'm changing the oil and filter this weekend so I'll be down there anyway.

I'll let you know.

I would like to know how you resolved it too. I have the same noise and it is embarassing when pulling through a drive thru and the rattling begins. Thanks for any help you can provide.

Hey 98LXand99LC,
Did you ever get this issue fixed? If so, what was your resolution?

I just fixed my rattle last night. It was not the heat shield but was a loose and broken muffler clamp on the exit side of the muffler. If mine was that bad i.e. the bolt had actually broken off maybe the slight vibs are a result of a weakening clamp.

Just a thought.

I got under mine this past weekend while doing the oil/filter change. Checked all my hangers and heat shields, didn't find anything out of order. I tugged on the heat shields above the cats and haven't noticed any rattling since.
