Hi my estima is making a ticking noise when driving especially when slowing down or at stand still also the exhaust is rattling.i had a new one put on eleven mths ago.im going get checked but wondering what the ticking could be

On that particular vehicle, and is very common, the rear upper strut mount rubbers wear out and cause a rattling noise. The noise is influenced by road conditions and speed and will vary in noise intensity.

The noise could be due to worn universal joint on drive shaft. Could be going bad. Slowly starts as a rattle with a little vibration and over time it gets worse. If there's no propeller type drive shaft, running down the center under the car, then it is something else

Hi Graham,
I think you should look at the heat shields often attached to the exhaust, sometimes when at idle they can vibrate and rattle and make a hell of a racket. Have your mechanic take a look at these it shouldn't cost very much if that is the problem

Have a look at the shrouds around your exhaust system, they are prone to shaking loose and rattle on over run.
Try giving your exhaust a bang ( with your hand when it is cold) and see if it causes the noise . Follow the noise.
Sometimes the baffles fall off inside the muffler and rattle around inside too.
Happy hunting!!

You have a loose heat shield or a broken rubber mount.

jack your car up make sure you put some thing under need like a jack stand ( just for safety) and manually shake your muffler usually rattling noises are cause when metal rubes metal.

Hi.
I think the problem is the power take off for the front fan ,steering etc. Underneath the middle of the car you will see what looks like a small propshaft pointing towards the front with a doughnut shapped mounting bolted to each end. These rubber joints wear and rattle on tick over or low revs cost is about £40 for the 2 from Japarts
Takes about 2 hours to change.Hope this helps Good luck

Check your converter on your exhaust when it's running and see if the noise of rattling is coming from there.If it is you have a plugged converter,it's broken up and in piece's which will make noise and no power especially when calling for power.Be sure to let exhaust cool before repair is done.If the engine is making the noise like a knocking sound you should bring it to have it checked.Hope this help's.

Could it be an exhaust leak? A minor one can make a ticking noise.

I had the same problem! I crawled underneath the car and discovered that a heat shield on the exhaust header pipe was corroded and rattling against the exhaust pipe. (Before the muffler)
I removed the portion and clamps and solved the problem. Give it a try.

sounds like the problem is brake related. That ticking you're hearing is your front brake rotors, clicking against the sides of the brake caliper. As you speed up, the clicking will get faster untill you won't be able to hear it, (it's still there, it's just inaudible at such a rapid revolution) upon deceleration, you will notice it more prominently, clicking in rhythm to the speed of your wheel's revolution.
basically, It indicates your brake pads are worn down. Unfortunately the condition will get worse, louder, and the car will become extraordinarily more dangerous to drive as front braking will be compromised if the vehicle's braking conditions persist.
A qualified mechanic will setup the brakes, rotors, check for warpage, hone the rotors if need be, and be able to install a proper replacement pad.
