Rattling down the road...

[Harvey]

Anyone know of some tool to make the car shake/vibrate to help spot sources of rattles ?

Have a buddy take the wheel and drive around while you seek and destroy (the rattles). Other than that, maybe you could put the car on a dyno, engage cruise control and go to town. Option 2 seems excessive.

i noticed it too, but it went away after some hammering and smacking..

The car's one year old now (18 000 KM). I fixed the first rattles I got by rescrewing the roof , the thread is here :


http://www.ft86club.com/forums/showthread.php?p=1823408


The car's full stock, but the shocks were replaced during 15000KM maintenance due to a leak. All this was done at the Toyota Dealer (who I mostly trust).


A few days after this (consequence or not) I started to get a new rattle from the rear left area, my daugter's been in the trunck (while I drove around a bumpy parking) and believes it's from the rear left wheel area. I've done a bit of messing around, but not found anything that fixes it.


So I took the car back to Toyota yesterday, they inspected the shocks and say they see nothing wrong, although they aknowledge the noise is wrong (we went for a drive and he clearly heard the noise and says it's wrong).


There are taking the car back for 2 days to do a thorough inspection. On a positive note, I'm happy to see they take these rattling requests pretty seriously, with a defined process : Take the car for two days, remove the trimmings/garnishes, test/inspect to locate sound (with some specialised tools)... if they don't find it they report to Toyota who apparently sends an "Expert" and if necessary takes the car to a specialised rattle tracking plant (whatever that is). In all cases, he says abnormal rattles are under warrany and are taken seriously by Toyota. I'll see how true this turns out ot be .....




But basically my question is: Why don't dealers have "vibration benches", they'd just park the car's wheel on a plateform, and then they'd make it vibrate and control frequency and amplitude, that way they'd save all this messy driving around with people in the trunck! Further, if such a machine exists, I wouldn't mind having one myself (for my other cars). Be cool to just have the car standing there and making the sound while I can crowl around, get under it, open close the trunck, .... I'm sure this is possible...

Because it's a cheap sports car, not an 80k luxury vehicle

Get a grip, put the hammer down, and drive the damn thing. Quit being a ninny

It's pretty common for them to bring an "expert" for engine stuff they say they are bringing a toyota "engineer"

West Texas. Lots of rattlers to track there.

That's the service center that's surrounded by really crappy roads that they can beat your car up on to find the noises.

I've discovered that subwoofers tend to identify a lot of rattles as well.

just gut the interior and then any NVH will seem normal.
