Xr6 Ratcheting Metal Sound Heard Under Acceleration

[JBJARROD]

Hi I have a Bf Mk1 Xr6 turbo, 6 speed auto sedan.

Lately I have noticed a metal (ractcheting sound) caoming from underneath my car under reasonably harsh acceleration and changing down gears. (sound like tools are loose in the back of the car but definetely not this)

Easy way I have showed people this noise is by putting the car in drive, hand brake off, foot brake on hard, the back of the car dips when a tap of the accelerator is made, there are several high pitched metal sounds coming from under the car.

If I continue to tap the accelerator these noises start to stop after about 7 or more creaking and metal sounds heard (as if something is now under load).

So to make the noise again I do the same above but put it into reverse.

What I have done so far is replaced the uni joint in the drive shaft just past the centre bearing but still noise appears, im thinking centre bearing next but not too sure about that.

My car only has 56000kms on it and out of warranty unfortunately so no go with warranty.

Gotta love the falcons, bloody diff thud is awesome hey!!! but that is another issue we all know of.

Please help

Sounds like diff bushes to me.

Is your car standard? Not pinging/pinking is it?

Ok guys, took it to ford, they fixed it!!!!!!!!!!!!!!

Basically if there isn't enough grease on the spline that connects the rear shaft with the front shaft (between gearbox and diff) it will make this sound.

Takes about 2 hrs to do and involves making sure the driveshaft is put back on the same way it was put on due to balancing issues. Just put a fair bit of grease on the spline and clean it up, put it back together and there you go.

NOTE: Id however recommend changing the uni joint while your at it cause it has to be pulled apart anyway to seperate the two shafts.

sounds like that is my problem also! when placed into gear (auto gearbox) and mainly reverse it make a metal tink noise like as you said spanner bouncing around.

Car has nearly 70k on it.

Mine does the tinktintink too.

Like yours, not really on accel, more when I put it in to reverse and hit the throttle (even lightly).

I thought I read somewhere on here that it was to do with the brakes/handbrake? Some shim or something...

I have the same problem

Thought I would give an update regarding the issue that I had fixed by Ford.

Well after about 5000kms, tune of 341rwkws and spirited driving the noise is back again damn it. Goood news is I know how to stop it but im a little annoyed it only lasted for 5000kms!!!

Anyway another $25 bucks for a uni joint and $120 for a few hours labour for them to grease the tail shaft up again!!! My car is turning into a major money pit!!!!

In relation to the noise that was rasied about handbrake and shim noises etc I think I know the noise you speak of but its no where near as loud as the metal driveline sound im speaking of.
