ratteling noise when breaking

Topan · **Posted:** Wed Jun 03, 2009 8:47 am

Hi there.
Something new appeared on my 2005 CRD.
I got a ratteling noise from the back breaks when applying slight break power.
If i break to stop, then i got power and no noise, but typically going down hill, slowing down before a curve, i got a distinctive clonk-clonk-clonk noise that is in synch with the speed of the car.

my mechanic found nothing (...why can i see some funny smiles... :wink:

)

Anyone has an idea ? (aside stopping applying breaks or crankking up the CD player to cover the noise :wink:

)

My disks and disk pads are all in good condition.

thanks

Blaise

Sounds like a floating pin for one of the calipers could be loose, I had a similar situation one time. Also a possibility - Hub Bearings (not sure if the KJ has rear bearings like I'm thinking of) or part of the suspension is loose.

i have check the calipers pins. didnt find anything loose there
Will check the bearings.

I have tried since to shake the weels with the KJ on the ground, it is possible to hear a loud clonk. Looks like something loose somewhere, i just cant find it... :roll:

Have you checked your rear differential joint. Mine went dry at about 65k replaced it with a greasable joint. No noise since in the rear end. Just a thought

Sounds like a bearing then. Jack up the back and see if the wheels wiggle. ANYTHING is a sign of either a loose bearing nut, or a trashed bearing. Change them out either way, b/c if the nut worked itself loose somehow, the bearings WILL be trashed in short order. Hopefully it didn't rip up the mating surfaces.

Here we are !!
The problem was my rear axel...it was bent...so i had to replace the axel, the bearing and the gasket...
and it happened like that. my wife had made a 180 in curve. I still have no idea how she managed to do that. i take taht curve everyday since and really try hard to got a 180 as well...but no way...

cheers
