    Punto's back suspension--THUDD noise??

    Hey
    iv been driving my fiat punto mjd for the last month... i am noticing i big " THUDD" noise from the back tires as soon as it comes down after a speed breaker or bump?? its continues to come even if i drive very sluggishly in the speed breakers.. is this normal for a punto??
    is it suspension issue or tyre issue ( JK tyre 165/80 R14)??
    the tire pressure i keep in all 4 tyres is 32-33psi

    It is normal Do not worry.

    What's That Sound?

    I found this article very informative (source - http://www.popularmechanics.com/cars/ho ... ir/1833626)


    A moving car is a complex symphony of sound, most of it reassuring—tires humming, engine rumbling, tailpipes roaring. But every now and then a dissonant note creeps into the mix—and the alert driver's ears prick up: Did you hear that? Here's a guide that identifies those oddball sounds and helps you sort out which conditions you can let slide and which ones mean repairs—and how fast you need to make them.

    THUMPTHUMP
    THUMPTHUMP
    THUMPTHUMP

    WHERE: From one or more tires.
    WHEN: At low speeds, especially in the morning. Speeds up with car.
    WHAT: Flat-spotted tire. As the tire rotates the flat spot thumps on the ground. Nylon-cord tires will flat-spot overnight and make this sound until they warm up. It's usually worse in colder weather. You can permanently flat-spot the tires by locking up the wheels, grinding massive amounts of rubber off the tread in one spot.
    URGENCY: Nada.
    FIX: Replace your nylon tires with steel-belted tires. If you've ground down your tires like a pencil eraser, you can either live with the vibration until wear reduces the flat-spotting or buy new tires.

    FFFFffff ttttFFFF ffff ttttFFFFffff tttt
    WHERE: Under the hood.
    WHEN: Most noticeable at idle.
    WHAT: An exhaust manifold gasket has failed, venting hot exhaust gases to the air.
    URGENCY: It's not getting better on its own. The blowtorch of corrosive gases will eventually damage the manifold. Oh, by the way: Carbon monoxide from the leak may make you drowsy or dead.
    FIX: Replace the exhaust manifold gasket before the leak eats a hole in the manifold.

    Ticktickticktick
    WHERE: Under the center of the car, toward the rear.
    WHEN: While in motion and varying with road speed.
    WHAT: U-joint (rwd or 4wd only). A U-joint in your driveshaft has finally run out of grease, is getting loose and is about to fail.
    URGENCY: That's really just an urban legend about cars polevaulting over broken driveshafts when U-joints fail at speed, right?
    FIX: Replace all the U-joints and keep the new ones greased regularly.

    EEEEEEEeeeee
    WHERE: Inside the wheels.
    WHEN: Slowing down; it's sometimes worse on damp days.
    WHAT: Your brake pads are stroking the discs like a violin bow.
    URGENCY: Sometimes they do that. Your brakes still work fine.
    FIX: Try new pads, adhesive to hold pads to the piston or shims to insulate the piston from the pads. Another option: earplugs. (Sometimes the sound is difficult to eliminate.)

    SSSSSSSSSSSS
    WHERE: Under the hood.
    WHEN: Anytime the engine is running, but it's most noticeable at idle speed.
    WHAT: Vacuum leak. A rubber or plastic vacuum line or fitting has split or fallen apart.
    URGENCY: If you're wondering why your Check Engine light is on and why your car idles poorly, this is probably why.
    FIX: Reconnect or replace the line.

    Clang
    WHERE: Under the center of the car or truck, near the middle.
    WHEN: Starting off at traffic lights. Most often heard on pickups with automatic transmissions, not manuals.
    WHAT: The splines that allow the driveshaft to change length where it connects to the tailshaft are binding as you slow down and then releasing when you start off.
    URGENCY: Annoying, but They All Do That—or at least some of them do it some of the time.
    FIX: Packing the spline area with special grease helps for a month or so. Or just sell the car or truck.

    ThunkThunkThunk
    WHERE: One or both front corners of the vehicle.
    WHEN: Going around slow, sharp corners under light throttle.
    WHAT: A CV joint that allows your front wheels to turn and still be powered is loose. The boot has failed and let out all the CV joint's grease, or maybe it's just time for it to wear out.
    URGENCY: Don't leave town. Don't use a lot of throttle around sharp turns. Your car will stop suddenly when the joint completely fails.
    FIX: Replace the entire off ending half-axle.

    CLUNK
    WHERE: Front end.
    WHEN: Initially, when parking; eventually, over small bumps.
    WHAT: The ball joint that connects the suspension arm to the upright has lost its lubrication and the metal-to-metal contact is wearing it out.
    URGENCY: Make an appointment. Avoid bumpy roads, curbs and potholes.
    FIX: Replace the ball joint.

    GrumbleGrumble
    WHERE: Front of the car.
    WHEN: At idle. (Check for weeping coolant at the bottom of the water pump, too.)
    WHAT: Water pump bearings.
    URGENCY: When the bearings fail completely, the fan will pull forward and slice a nice big smile-shaped chunk out of the radiator, making it leak profusely.
    FIX: You need a new pump.

    Yyyyoooooowwwwrrrrrrr
    WHERE: Under the hood.
    WHEN: Whenever you rotate the steering wheel all the way to the left or right steering stop and hold it there.
    WHAT: The pressure relief valve inside the pump is dumping excess power-steering hydraulic fluid back into the reservoir. It's supposed to do that, although maybe a little more quietly.
    URGENCY: No big deal.
    FIX: It's normal. Actually, you should check the level of powersteering fluid in the pump. Don't hold the wheel hard on the stop like that; it annoys pedestrians and is tough on the belt.

    YEEEEeeeeeaaaaawwwppp
    WHERE: Under the hood.
    WHEN: Right after startup until you rev the throttle a couple of times and the rubber warms up.
    WHAT: Belt squeal. A loose or glazed belt, bad tensioner or misaligned pulley.
    URGENCY: Make an appointment, and don't take a long trip. This won't go away on its own—until just before the belt fails.
    FIX: Check belt tension and pulley alignment; replace the belt.
  4. Re: List of Known Faults/Issues

    I am getting a rattling sound from my steering console. Specifically from the Blue & Me Controls on the left part of the steering. It sounds as if some nut is loose and moving around. This sound comes up when the car moves on uneven surface, potholes, etc.

    Any clue about the reason? My service is still 5000 KMS away. Should I get this checked now or wait for the service?

    I had some rattling from the steering too. It is nothing serious, I managed almost 2000km with the sound since I was on a road trip. If it irritates you a lot then fix it. For me it felt as if my car has suddenly become old and could not wait for a service to be due.

    When I cross speeds of 80-90 Kmph there is a hissing noise from the right window as if air is coming in...when I asked the TASS person he said that it is due to high speed wind passing between the rear view mirror and the window and it is not air coming inside the cabin. Anyone facing this issue?

    I have driven my Linea at speeds more than 140kms, no hissing noises. Only the tyre noise can be heard. Might be you would have shut the other vents of the AC & more air is passing through the right hand side vent. Check.
  8. Re: Squeaks, Rattles and niggles

    The TASS person is correct. Its the windpassing through the narrow tunnel between the rearview mirror and the window.
    You will notice this on the left side as well.

    Has anyone faced issues with the rear seat lock in the Punto? (2/3 split version seats). i see that in my car the lock does not prevent all direction movement. I see some sort of play in the locked position which makes the seats move a little bit horizontally, causing some sort of tak tak noice while going over path holes at slow speed.

    has any one faced this issue, what is the solution. is this something that we can claim warranty for a replacement?

    Narayan, this issues has not been reported yet. Even I dont have any issue with it.
    Visit service center, either they should fix it or replace it.
