The car is a 2002 SUZUKI ESTEEM GL 1.8, sedan, automatic transmission.

On the highway, above 55-60 mph, there is a noise which increases if I accelerate more. The noise comes from near to my feet. The noise is periodical, "rotational", and not much smothered, . It is almost the same type of noise you hear when you shake a pencil in a glass (but low register). Or the noise that a shaky exhaust pipe would do. But I already got it checked. I also check all the fluid levels.

The noise also happens when the car goes on road irregularities at high speed.

After having being on the highway, the noise continues for a few minutes, at low speed, only when I turn.

I had a look under the car, and the elements that are close to my feet are:
- the automatic transmission
- the connecting rod from it to the wheel
- the shock absorber
- the steering link
- the connections between the car frame and the wheel
- the wheel.

I was first thinking that the problem is coming from the automatic transmission but I reached 60 mph with the 3rd and the 4th gear, it makes no difference. Also, the casing is pretty thick and filled with oil so I don't think the noise would be the same. Maybe the torque converter?

My last conclusions are that the noise comes from the shaft drive between the transmission and the connecting rod that goes to the wheel. The change in angle when the wheel goes on an irregularity could explain why it happens in this situation too.

Hi damolitoy,

Thank you for the donation.

Noise fault are never easy to detect what more online.

From the symptoms description, if the noise disappears when the accelerator is released and occurs only when there is partial load, the most likely cause would be the CV shaft inner joints. Check the joints for grease leaks which woulod be splashed all over the body around the joints.

Inefficient lucbrication would cause the noise and mostly it would be accompanied with a slight vibration in the steering wheel or body during slight acceleration.

Check the CV inner joints for excessive side play when holding the shaft and moving it up and down. Excessive movement means the joint is bad.

Hi, thank your for your answer.

I checked the joints. The rubber is old but there is no leakage nor tears.

I also checked the shafts. The only negative thing is concerning the passenger-side transaxle. In fact, this transaxle is composed of two shafts because the passenger front wheel cannot be reached directly. At the joint between these two shafts, I noticed an important play, AXIALLY. The moving part is the green part that I photographed here:

The play occurs uniquely when the wheels are turned to the right, and is about a fourth of an inch.

Is it normal?

Do I have to replace the complete transaxle or can I just replace the joint / grease it?

Thank you.

Sorry for the dely in replying, seems notification was not sent to me for your reply due to some technical glitch with my ISP.

That is the inner CV joint and if there are excessive axial play, it would cause vibrations and abnormal noise.

Hold shaft at rubber boot end and test for axial play from within the ( green ) joint. If the shaft moves by more than 1/4 inch, remove the rubber boot to check for proper lubrications from within.

If the movenent is between the green part and the inner half shaft, it could be due to worn splines of the shaft and replacement is required.

The bolted bracket has an internal bearing and that cousl be the cause of the rough noise. You would have to remove the outer shaft to test for coarseness while tuening the shaft.

Hi damilotoy,

Did you ever get your rattle figured out? I've got the exact same car as you (2002 Esteem wagon) with the exact same problem. Rattle that sounds like exhaust (but isn't) at highway speeds and when cornering at low speeds.

Just found this forum and your question. Any advice?

Thanks,

W.

Hey Gyre,

no, I haven't figured out what is the problem.

However, the noise is kind of gone most of the time. I have stil some bad vibrations at high speeds but it is not too bad so I'm not worried anymore. However, I have plenty of other issues with this car.

Let me know if you find out!

Hi Damolitoy,

I've sort of got the same attitude about the noise: sounds awful but hopefully isn't anything serious, and anyway it's been going on for over a year now. The frequency of the rattle is always the same, which makes me think it's just something vibrating against something else, rather than part of the engine or drive train. My latest theory is that it's the radiator vibrating against something. It's such a hard problem to isolate because I can't make the noise except when driving.

Apart from that, I have to say the rest of the car has been pretty good. No major problems.

Cheers. Will let you know if I figure it out.
