Had this 'knock' for ages. Comes from drivers side rear sounds like metal knocking on metal but more of a 'crack crack'
Only get it at low speed turning left on an uneven surface such as entering my driveway
Had my exhaust guy check it out and all good
I cant see anything obvious. Local mechanic had a look but wants an hours labour to fully check it out as he can hear it but cant see anything obvious on hoist
I dont mind paying for the work but wondered on your thoughts
I have Kings Lows fitted
I've tried to replicate the noise by leaning/ bouncing on the rear end and jumping up and down in rear seat but no sound
Happens with or without passengers in the back
Cheeers

Rear swaybar bushes may be stuffed

Having Googled rear swaybar symptoms I think you are correct.
Is it a big job? The bushes dont seem too expensive.
Are the aftermarket ones better than the originals
I have done 85000 km

I wouldn't expect it would be especially difficult, the front ones would the the more difficult ones to replace.. maybe an hours labour at a mechanics?
Some like poly bushes, I prefer OEM rubber bushes. Poly ones may be more durable in some cases, but they create more noise and are harsher on components.

Replacing the rear sway bar bushes on a 380 is a piece of cake, have done it three times myself so far. Save yourself a few $ and DIY.
OEM rubber ones are fairly cheap from a stealership, less than $20 the pair I think.
You don't need to jack the rear end up all that far to get at them.
As always, make sure the car us properly supported on ramps or jack stands, hand brake on and (front) wheel chocks in place, before you slide underneath.
Four easy to get at bolts, two on each side. You might need a breaker bar to crack them as they are torqued up fairly tight.
Liberally coat the insides of the new bushes with the right type of grease before you fit them, otherwise they will creak, groan or knock. I've used copper grease and white lithium grease, both have worked well.

As above, use genuine, are better but also use a smear of rubber grease (is red in colour generally) to make sure they do last and also do not squeak

Cheers Guys
I've ordered them and I'll let you know the results

ohhhh so thats what that crack sound is... i have the same issue, I'll also get on to the sway bar. thanks guys !

I had the exact same symptoms on my 380, turning left I would hear a metal on metal clang, thought it was suspension but when I had my muffler replaced the sound completely disappeared, turned out I had a loose muffler, but looks like this has already been checked?

The strange thing is the noise travels right through the car and at times seemed to be from rear window and/or sunroof.
Eventually I strapped my wife in the rear seat and said you dont get out till you tell me EXACTLY where the noise is coming from

So I replaced my rear swaybar bushes and .,......still the noise!
So I take it to my local dealer who takes it for a drive and pronounces its ..... THE SUNROOF
I sit in the passenger seat with the headliner cover open and as we turn left I can feel the frame moving everso slightly
They give it a good grease but no change
Suggest removal but big bucks. Whereto now?
At least I know its nothing dangerous but bloody annoying. The noise travels right through the car. I may have to sell it as its driving me nuts now
At least I have new rear swaybar bushes.
I know what your thinking how can the noise be from sunroof and sound like its from the rear but the sound travels through the whole car and hard to pin down.

I don't have the same problem, but I've always had problems tracking down the sources of creaks, groans, squeaks and rattles.
Most of the time, like you, it's caused by something not even close to where the sound is coming from.
Maybe it's just a peculiarity of the 380 chassis, body and interior, setting up all sorts of strange harmonics?
I think it's also partly due to the 380 being a fairly quiet & refined ride, so that any extraneous creaks, groans, squeaks and rattles are very noticable & annoying.

Googling how to fix noisy sunroof found a Toyota site
Similar issues and even mentions 'swaybar' bushes haha


Hello,

I'm a first time poster. After a week of owning my 2012 Camry SE with moonroof, I heard this persistent moderately loud knocking noise, which sounded liked it was actually coming from the front left wheel area. As soon as you start driving, the knocking sound occurs, stops, and stops again. It is most persistent while driving over uneven street pavement. I thought maybe it was a bushing, control arm, or swaybar not tightened up. The first Toyota dealer I went could not reproduce the issue, and 45 minutes later while driving back from the dealer, the knocking noise reoccured. Why it took sound long to reproduce, I really can't tell you because there was plenty of uneven pavement around that Toyota dealership.

The 2nd Toyota dealer I went to this morning identified the issue by driving it 20ft. The service tech said the knocking noise is coming from the moonroof, and that the knocking sound is caused by the moonroof hitting metal on metal due to a lack of adequate insulation between the moonroof and the left headline. Toyota called their dealerships about two weeks ago and reported this as a known issue during a conference call per the Service Department tech. My car is being fixed under warranty next Tuesday.

I hope this knowledge helps someone else get this fixed on their Camry SE '12!

I've had the same noise and always pretty much thought it was the sunroof. It doesn't happen often enough to me to actually annoy me much - only when the car is in a position that the chassis would be under significant stress, such as turning in to a steep driveway. I reckon it's probably something just moving slightly, such as the sunroof frame or rubber seal against the glass/metal. Don't reckon the next car I get will have a sunroof... It was fun and a bit of a novelty when I first got the car, but rarely use it now.

If you end up finding a solution, certainly post it up!

Anyone know how to tighten sunroof frame?
I can feel the flexing with my fingers with the headliner cover in open position.
