Drive shaft noise - Need help

girishab · 28th March 2005, 13:03

I have been getting some noise from the drive shaft of my Ikon, off late. This usually occurs when I shift up, say from second to third gear at about 40kmph, and then floor the pedal. It stays for about 3-4 seconds and then everything is smooth. It happens in almost all gears from 3rd - 5th. The noise sounds like some component is not able to take the load. This does not happen if the acceleration is gradual. Is this something serious to worry about?

Sounds like there is some play due to wear and tear leading to gear backlash - does this happen when the car is turning ? Could mean a riveshaft replcement or somedifferential bearings needing replacement. How many km has the car done ?

A good way to check if your driveshaft is on its last legs is to turn your wheel to full lock and take a turn. Do this in bopth directions. If you hear a clicking noise, then it's time to change you driveshaft.

Also make sure your driveshaft rubber covers are not torn. This would mean the grease would get dirty, causing noise. If you catch it and change the cover in time, you may get away without too much damage to your driveshaft.

If it is more a one-time noise like a "clunk" when you accelerate only, then it could be your balljoints or tie-rod ends.

Well, this occurs mostly when I am not accelerating and not during turns. My car is about 10 months old and has done only 6k Kms.

Rtech · 28th March 2005, 14:27

Well, that's odd. If your car is only 10 months/6000km old, it would/should not be your driveshaft.

What kind of noise is it? Is it a whine, grating noise etc?

Another thing it could be is engine knock. As you say, it happens when you floor the throttle. If you floor the throttle from too low an rpm, the engine may knock a bit. And, as you say this noise goes away after a few seconds, showing all the symptoms of engine knock.

The cure for this is not to let your revvs drop too low in any gear. Downshift and accelerate away.

That is alarming ! Is n't there a warranty period ? worst case ask for good will or ask Autocarindia to poke their nose in !

Rtech:

The sound is more like a grating noise. Also, my car hits 40kmph mark at about 2500-2700 rpm in 2nd gear. If I now shift to 3rd, then am I letting the revs drop low for the 3rd? I am new to driving so I may be doing things wrong here. By the way, mine is 1.6 Ikon and I use Speed 93 regularly.

Ajmat:
Yes, I do have the car covered under warranty. I will surely head out for the service center and get them to inspect it.

Thanks
Girish.

That's bcoz you're letting the engine get bogged down. It's common for all cars (except ones that produce considerable torque at very low rpms).

Check you car manual and see what the optimum shifting point in each gear is. If the 3rd gear is tall, then the revvs will surely drop.

Shan2nu, I'm not getting this. Explanation please..

When the engine revvs drop too low, the engine gives out a sort of clanking sound until the revvs increase.

Like he said, for 3-4 secs and then its smooth.

Though my car doesn't clank at 40kmph in 3rd, it depends on how the car is geared and will diff from car to car.

Maybe 2700 is not the ideal rpm to upshift. If it's a driveshaft problem, then even a shift at 3000 or 3500 should produce the same sound.

The problem looks to be more engine related than the driveshaft.

But a trip to a service station is a must. Get it checked asap.

Thanks everyone. Will pay a visit to the service station and update you guys on what they say.

That's the reason why I asked you. According to girishab, noise is coming from drive shaft. What you're saying here is typical pinging noise.

Maybe, coz pinging is most likely to happen when you floor the throttle and if you read what he said in the opening message (quoted below), it sounds very much like a pinging problem.

well girishab, it does seem more like a engine noise rather than drive shaft noise. but anyways, since your baby is literally brand new,get the CV joints checked, just in case.
and also, the ikon runs even on 87 octane gas, so 91 octane might not give the desired performance at mid/low-range, as the 1.6 sports a compression ratio of 8.4:1, and hence, the engine could knock/ping at low revs.
