Caster = Bent lower arm.

Post the alignment readings.

Unfortunately could not do the readings post replacement of struts due to workload at office. I had to wrap up pending issues. Infact plan is to start tonight at 3.30am.

Well, since the camber is taken care of, And the alignment guy must have done a toe setting before, you are okay for the trip for now atleast, but after getting back, get a wheel alignment done to check the caster and if its out ( which it will be as they have not done anything to the lower arm), replace the lower arms. Don't worry, caster being out won't wear your tyres out, but there will be a minor pulling to one side at high speeds.

Returned last night after driving nearly 2500 kms covering Vizag, Araku, Tyda & Borra Caves.

Let me try to explain the vibration issue now. I'm seriously confused. On highways sometimes the car would allow me to go all the way to 120kmph without any vibrations at all. On most other cases the moment I crossed 100-110kmph there was heavy shuddering from the front left side of the car. Once you reduce the speed to 90kmph there would be no traces of vibrations. Sometimes (very rarely) the vibrations would start even at 80kmph.

Is there really another problem or 100-110kmph is the natural frequency of the car/engine. If that was so then why is the front left vibrating?

Mr. Lokesh from Surakshaa Car Care Pvt. Ltd. called me while I was in Vizag to get a status of the car during the trip. I also told him about this issue. He told me to bring in the car back for check up once I was back in Bangalore. But surprisingly in the past I have done highway trips and never faced this issue before.

Will provide an update post checkup.

Tell me something, do you remember or can you check how much balancing weights went into both your front tyres ?

Also are any of your front rims bent ?

Lastly, Did they check for any 'wheel bearing play' as well as tie rod end play while the suspension job of your car was done ?

Secondly, I find your 'vibrations' changing issue strange. I guess to observe the actual speed at which the vibrations occur, you need to be on miles and miles of empty roads where in you can stay at a particular speed, go up a little, then up a little, then up a little and keep observing what when the vibrations appear.

I generally check this on the Mumbai Pune expressway as that is the most empty and long road I can find. It used to be the Chembur - Mumbai freeway before, but the road is not leveled properly because of which my cars floor and steering vibrates there above 150 kmph, which I had read in Frank Mehta's Swift Diesel thread too and my friend too who has a Polo tells me that his car has a tendency to vibrate there too, So I stoppped checking anything there.

Hi,

My 2008 Honda City ZX GXi CVT was recently taken for 70k service and i had observed that the car was showing very high vibrations at idling rpm. This was prominently felt when stopping at signals and even after shifting to neutral. So the service technician diagnosed the issue and reported that the cause is Silencer A & Silencer B which is touching the underbody and causing the vibrations and need to be replaced costing around 35k. Before going ahead with the replacement, i just wish to confirm if anybody else faced similar issues and what can be the other solutions to rectify the same.

Thank you.

Unless the silencer units have broken and are hanging and touching the body whole unit replacement is NOT required. So first check if it is just the rubber mounts that hold the pipes in place that is broken or the whole unit that has corroded.

Leave the car idle over night and before you start the car for the day try holding the end pipe and shaking it. You might be able to figure out if there are any apparent issues with this. Overnight parking to allow the parts to cool down, so caution and do not burn yourself

Next is checking engine and gear box mount, which can also cause undue vibrations.

Thanks Jaggu,

I tried examining the silencer unit but could not see any apparent damage. Also its not shaking much. Its properly fixed. I doubt whether that can be the cause of vibrations. Need to check the engine mounts next. Can you suggest any good service center other than ASS to rectify this issue?

I am facing a problem with the brakes in my car for more than 1 year.

Problem : Front left brake makes rattling sound when reducing speed from medium speeds. Brake pedal pulsates (car is not equipped with ABS) during panic braking. Braking performance is otherwise normal.

Car : i10 1.1 (2008 model) (completely in stock condition except music system, remote locking, seat covers and floor mats)
Kms : 28k (mostly in city traffic)
Tyres : Bridgestone OEM stock tyres on stock steel rims
Rotation : 5 tyre rotation performed at every 7-8k
Alignment/Balancing : performed after tyre rotation at every 7-8k

The problem started when I took my perfectly working car to Hyundai A.S.S. for a periodic service (at 22k kms). The service advisor found a leak in the front left strut and advised a replacement to which I agreed.

When I received the car back after this service, there was a rattling sound (grunt grunt sound) coming from the front left brake (when reducing speed from medium speeds). The service advisor convinced me that the sound would go away on its own after a while. But it never went away even after 1 year.

The rattling sound is very annoying, even with the windows rolled up. But braking performance is otherwise normal.

I normally try to avoid aggressive braking, but on rare occasions when panic braking is required, I feel the brake pedal pulsating when reducing speed from 80 kmph to crawling speeds.

I got the brakes inspected in the next routine service at a different Hyundai A.S.S. The service advisor told that the brake noise is because of scoring of the disk and there is no way to reduce the noise except to replace the disk. I didn't replace the disk since he suggested that there is still more life left in the disk and pads.

Please suggest what to do.

Few more related points :

- I have hired a washing guy who washes my car with plain water every morning. Like all washing guys, he also has the habit of sprinkling the left over water on the wheels to make them look clean.

- I don't use my car on a daily basis (because of car pooling). On some occasions, my car is left unused for a complete week.

Look for
1. Worn out caliper pin
2. Warped disc
3. Loose suspension bolt or hub retaining bolt

Waiting for 1 year wasn't a good idea.

Thanks for reply, sir.

I didn't wait for 1 year. In fact, I got the brakes inspected from another Hyundai A.S.S. They didn't find any issues. (I hope they were competent enough to spot a worn our caliper pin or a loose bolt)

I guess I will visit a different Hyundai A.S.S. for my next service and get it inspected again.

What should be the course of action ? Should I get the discs replaced during my next service ? Do the brake pads also need to be replaced along with the discs ?

Is it normal to replace discs and pads at 30k kms for a hatchback which is primarily used in the city ? (I must add that I learnt driving on this car and in my initial learning days, my braking technique was not correct. I didn't make use of engine braking and used to press the clutch while applying brake. On one occasion during the learning period, I also have driven down Nandi Hills in the same manner)

Not a question of competence, but looking in the right places. Get a technical specialist in one of the HASS to take a look and diagnose the issue. Service advisors are pretty useless in this respect IMO.

Car - Lancer.

I had vibrations, since i though the engine mounts are worn. It actually had torn mounts( I saw it while removing), I changed all the four mounts (indian make) since OEM is too costly. Also changed Four struts from Gabriel and also changed the Rubber kits in front strut bearing, and strut mounts. Since i had bottoming in humps and noise in fronts.

But even after change, I can see only slight reducing in vibrations. Still there is vibrations and also the steering pulling left and have to and fro moving towards right and left(waving) at low speeds. So i have to get pull the steer towards right a bit, while driving. I had changed the Tie rod ends and Steering ball joints, Still i feel hard. not feeling soft in suspension. What will be the cause of vibrations and much noise in cabin,

I got the noise from left front suspension , tak tak noise while turning. i am sure it is noise from strut bearings, But i had used old springs only. But other kits are new. I have decided to take it to A$$ , so that they will be much knowledgable in lancers. Let me know the inputs from members.

[Rudra Sen]

It's not at all clear from your post as which car you're talking about!
What made you think that engine mounts were the culprit?

I would like to assume it is a front wheel drive car and that sound is because of defective/damaged drive shaft.

[rajivanoj]

Thanks Rudra, I had the noise while turning full right turn, I think i can hear left end wheel side. Till now i had not that vibrations will also caused by drive shafts, I thought it gives noise only by full turn, and then it wont affect much, Thanks for eye opener. And also just now i called for getting an Xado repairing grease, it will reach to me by the end of the september from dubai. Thanks for inputs.

edit: Sorry for not giving details about car, it is lancer. But also the tak tak i specified is also happen in stationed, not moved. it is from struts. but the above also happens in full right, that is different noise from cv.
