Squeaking/Claknking sound while reversing

MRSSIIM3 · 07-22-2010, 02:28 AM

I was doing a couple high speed runs then i pulled over to the side to let the car rest for a while. I noticed while decellerating without pressing on the brake i heard a squeaking clanking sound. I then put the car in reverse and accellerated in reverse and i heard the same sound. It sounded like something was getting stuck in the rear of the car or something of that nature but i looked under the car and there was nothing stuck.

once again, it was NOT coming from my brakes and only happened while going in reverse or slowing down by downshifting

any thoughts on what it might be?

is the "rotation" sound engine speed or travelling speed related?

MRSSIIM3 · 07-22-2010, 02:48 AM

no it happens from dead stop up until ~30 mph in reverse

MalM3 · 07-22-2010, 02:50 AM

yeah.. but if you disengage drive (so engine speed falls to idle) and roll at 30mph is the sound exactly the same?

Or is it whilst the drivetrain is under load?

MRSSIIM3 · 07-22-2010, 02:53 AM

ooo sorry didnt get your question at first

its when the drivetrain is under load

MalM3 · 07-22-2010, 02:53 AM

can you "feel" the noise

MRSSIIM3 · 07-22-2010, 02:55 AM

no i cannot feel the noise. the car does not shake i just hear sounds

MalM3 · 07-22-2010, 03:00 AM

hmm, prop shaft bearing possibly?

MRSSIIM3 · 07-22-2010, 03:03 AM

could it be anything else? im gonna take it in for service tomorrow but im trying to get an idea of what it could be before i go in. would it be covered under warranty? (whatever it is?)

MalM3 · 07-22-2010, 03:37 AM

hard to say what else it could be...

Regarding warranty, you need to consult your agreement

But good to know you have a booking already
Let us know what it turns out to be !

MRSSIIM3 · 07-22-2010, 11:09 AM

kk will do thanks man

AlpineG05 · 07-22-2010, 11:10 AM

Sometimes when I go into reverse I have heard that noise as well. You cant feel it but I've heard it more than once so I'm sure of it. I would take the car to the dealer but I'll be trading the car in soon.

MRSSIIM3 · 07-22-2010, 11:55 AM

yeah im on the way to the stealership right now

hopefully they fix it instead of trying to tell me that its normal...

MRSSIIM3 · 07-23-2010, 04:17 AM

update: sound went away when i got to the dealership and things seem to be fine now...

as always

SSIMPS · 07-23-2010, 11:45 AM

My car squeaks in first gear both under load and not... up until about 20-25 mph and i have no idea what it is either.

MRSSIIM3 · 07-23-2010, 02:56 PM

the squeak youre talking about is a faulty brake sensor

theres a service bulletin out if you take it in theyll fix it
