Any ideas on what this ticking noise might be?

[lamborghinifan]

I have a ticking noise coming from the rear right of my 04RWD 4spd terry.
Sounds like a credit card/cable tie on bike spokes.
Only does it whilst driving, gets faster with vehicle speed, but seems to be related to engine RPM, ie at the same speed it ticks faster in 3rd than 4th.
I'm hoping it's not, but seems to be transmission related, anyone got any ideas? My mechanic hasn't any ideas, we originally thought rocks in tyres. I can only hear it with my head between my legs in the rear passenger seat, wife can always hear it.
Any ideas for a man going crazy?

Sorry, it was too hard to refuse. If it were road speed I'd look at the cvs, seen problems on lowered territories. Could be a grommet missing so the noise is transmitting from elsewhere.

by road speed, when i drop it back a gear at constant speed it seems to jump a little inline with engine speed, but not sure if it's the lurch from the change itself

Movement in the brake pad , you most likely have a pad that is a bit smaller or a caliper that its groove is a little larger and it moves making a tick with the revoultion of the wheels . Had it with 2 of my cars 1 ford one another make , both fixed by going to a after market pad

Verrrry uncomfortable way to hear a sound I must say. It is amazing though where sounds can only be heard, or where they "seem" to come from. That sound you describe sounds like an interference from a faulty capacitor, in the vehicle somewhere, ticking in the radio. Is you radio on when you hear this sound. I've heard this in my EF. I remember it being a capacitor but can't remember where. (Can't find the repair report neither, after 12 years ).

Your radio does not have to be turned up neither. Just as long as it's on or off.

Yep could be as simple as interference somewhere along the audio system. It will be the same volume no matter how loud or low you set the volume. Put your head next the speakers and see

Rear passenger seat - that's above the fuel pump.
If it is engine speed related and NOT road speed related, I'd start there.
Maybe it's normal.

should the frequency then change with the engine being revved in neutral?

Possibly not as the demand for fuel dosent change much free reving.

Have we decided whether it is road speed of engine speed? Is it the same speed in different gears? Does the drivetrain have to be under load, does it alter relative to load?

One out of left field, but I had something similar happen to me. Do you have mud-flaps on the rear wheels? I had a loose/misplaced one on an EF Falcon which would rub on the tyre at slow to moderate speeds (though the sound would disappear at a higher speed), producing an alarming sound.

Possibly ABS ring touching on the sensor?

This could also be a wheel bearing, check all of them.

I hope you haven’t upset any Syrians around your neighbourhood?

Also, could you please post a pic of you being driven around with your head between your legs, I’d like to blackmail you later with it.

(checks in driveway car hasn't gone boom and there's no pile of cinder, no only have upset aussies recently, they're all too busy watching footy to blow anything up)


thanks for the ideas a hundred an one things to check now.

rear pads have been recently been changed, what would be best way to try and find a click there, swap them left to right and see if the sound follows?

Another one a little out of left field...
The little weights used to balance tyres on the inside of your rim hitting the brake calliper?

hmm, unless the back wheel has gone out of shape, it's not touching when it's stopped, and there's no scoring on the inside of the rim i can see

You won't see it on the rim, but on the weights used to balance the tyres.
What happened in our Peugeot is that the tyre places stacked those sticky weights on top of each other and when I had the front brakes pads replaced, the calipers were a little wider due to the thicker pads and the wheel weights would catch the caliper on their way around.
Even if you jack the car up and just spin the wheels around, if it's that, you'd hear them hit without having to take the wheel off.

it's amazing how many respondents didn't read that bit.

sounds like it would be engine or gearbox or electrical rather than wheels, etc.
