Lexus SC430 :: Helicopter Type Noise At Speed Around 70 Kph (40 Mph)
Jun 8, 2016
The SC I recently bought is quite quiet except for a helicopter noise at speed.
This noise becomes obvious at around 70 kph (40 mph) but can be noticed at lower speed (volume much lower). I don't think turning the wheels or braking makes a difference.
Since it's speed-sensitive and there's no noise when the car isn't moving, I guess it's related to the wheels. I've just replaced the rear tyres last weeks; nothing changed. I've checked the tyre pressure today; may have got a little improvement (not sure) but the noise is still there.
Is this the wheel bearing noise? Or is this tyre noise? Could the differential make this kind of noise (the only other thing I can think of that's speed-correlated)?
Also, as an aside I pulled the fuse on the te/ti steering the other day because I'm too lazy to use techstream. I swear there's a noticeable improvement in the steering accuracy and feel. Really don't know why.

I have a rear wheel bearing type of noise that appears to come from the rear. My vehicle is front wheel drive and has 135K miles.
I checked the rear wheel bearing/hub assys on both sides and they had no play but I changed them anyway. Noise did not change at all. Rear tires have normal wear, no cupping or anything. Noise gets louder with increasing speed up to a point and then remains a constant level.
My next thought is to check the front wheel bearings/cv joints.

I am in search of a SC430. I know that from 02-05 it has 5 speed trans. 06 and newer has 6 speed.
Is there a big different in the drive? I just want to justify the extra cost for the 06 and newer.

2007 Ford Freestyle 90K miles.
I bought it used and it had a slight helicopter noise coming from under the hood. Mechanics at Ford dealership didn't find it remarkable. Now, 16 months and 15K miles later, the noise has increased in volume so much over the past 30 days that typical road noise doesn't disguise it. Folks are giving me looks when I drive by in the parking lot.
I have a clip of the noise posted if you want to take a listen: [URL] .... I've read some posts that this is symptomatic of transmission problems...specifically the insert shaft is grooved, warped, etc.

When I am driving at a higher speed and I need to pass someone or accelerate, the engine bogs down. I push the peddle to the floor and nothing. This does not happen all the time but it happens. But when I accelerate from a light or lower speeds there does not seem to be an issue. I recently had the value gaskets replaced because of a small oil leak and it seems this problem began after then. I have taken it back to the shop but the problem does not duplicate itself when they test drive it.

In my current speedometer the speed needle doesn't work i did everything and changed all sensors and checked all related issues and all is fine turned out the issue was with the speed gauge it self. So i bought my self a used speedometer.
Now my question is, how to dismantle the speedometer cause I want to take out the speed gauge from my old one a replace it with the new one i know its much easy to change the whole thing but I don't want to play with the mileage I have on my car.

I have a grinding type noise coming from underneath. Not there all the time..heard it last night while driving home....pulled over and waited for a while looked underneath could not see anything. Started off again heard it momentarily then it stopped....but I am thinking that this could be axle/wheel related/ball joint? No engine issue coming from the chassis underneath, possible bearing?
I have a 2003 Gx with 245K on it....but overall runs great!

So I was riding with no music on--had family in from out of town--and noticed a strange noise coming from behind the dash on the driver's side. Hard to describe but almost a liquid-type noise (although not a liquid) and repetitive. Doesn't happen all of the time but happens frequently. Not loud enough to hear over music or even road noise on a highway.
Almost a swoosh, swoosh with sort of clicking. Wish I could describe it better.

I'm getting a loud gurgling type pump noise when removing the fuel cap. It is really something I have never heard before on any vehicle. It's not a quick hissing noise. It is a constant motor type noise coming from the fuel filler. I tried it again today because the dealer was there, but since I have a 1/2 tank of gas it did not happen.
Each time I have needed to fuel up, I've heard it. So I suspect this noise occurs when the tank is low...within 3-4 gallons left.

I have a 2014 ES300H that I just purchased. After driving around for a while I parked it in the garage. After it had been sitting in the garage for around 6 hours, I hear a motor or fan type noise coming from the trunk area. It lasted for several minutes and then stopped. Is that normal and what the noise might be.

I have a 2006 Toyota Matrix. I want to change my manual transmission fluid in it. I have called dealerships and auto parts stores and keep getting different answers. I was wondering exactly what kind of fluid do I use and how much fluid do I use. I am not going to pay $219 for the dealership to do it but I want to make sure I put in the right kind and the right amount.

i keep hearing a noise under the dash by the radio. it is almost a gurgling noise if that makes sense. i don't know if it is the cd player doing something, or something else.

I have a 2005 SC430. When I start it up it makes a squealing noise, and the more I accelerate, the more it squeals. I read through this entire thread: [URL] ....
I did as PearlPower suggested and sprayed it with some WD-40 (the top center pulley area) and the noise stopped, but not for very long. Think I need a new belt.

Over the past year I have been hearing a noise coming from the rear of the car. It seems to happen when the car is running and almost sounds like the fuel pump priming itself, but it happens when the car is running. So I don't think it would be that.
It doesn't happen all the time, it might but I miss it due to the loud levels I tend to listen to the stereo at.
My other thought is that it might be from the one of the top motors to raise and lower the roof.

When I start my 2003 SC430 I hear this screeching noise. It sounds like it is coming out of the dash but it may be under the hood because my neighbor heard it outside the car.

There's been a recent annoyance that's appeared in my '03 SC 430 with 32K miles. I've noticed over the last 3 months that whenever I have the A/C turned on, after a few minutes, a soft chirping sound appears. It sounds very much like a cricket chirp to be exact, kind of high pitched, but continuous. It's even loud enough to hear over my music.
I realized that it came from the A/C because it was gone whenever I turned the A/C off. I initially thought it might be from the belts for the A/C compressor, but I couldn't hear anything from the under the hood with the A/C turned on. I'm thinking it might be something to do with how the coolant flows in the lines, but can't be sure.
I'll probably have it looked at during my next oil change.

Grinding noise (light) in the steering column on turning the ignition key on, after few hours of parking in hot sun only, the movement of steering column is to the set memory, after that no noise, cold start in the morning is always noiseless, feels like it needs lubrication?

There is a noticeable amount of wind noise on the driver's side (obviously with the top and all windows up). Haven't ridden in the passenger seat so not sure if it's there too.
The top closes perfectly, so I'm assuming it's the driver's side mirror.
