Help please noise judder, donk

Hi

I need some help, I have an 06 d3 manual which developed a rotational “donk” quite heavy, felt like it was being held back (binding).Noticeable a low speed <30mhp on acceleration and <10 mph on deceleration. Above 30mph no symptoms It also exaggerated on hard lock in either direction

Since I already knew the rear diff was On the way out and leaking oil, I changed the rear diff (used) but from JOS and looked good. While changing I noted the prop bearing rubber was shot so put a new prop on

Still there

Spoke to jos advised probably front diff, I also noted some play I. The front prop

Both changed (used) JOS

still there

With the help of my son, noted the noise coming from front right

Decided it had to be wheel bearing or driveshaft

Changed front hub (new) and driveshft used JOS

NOISE STILL THERE!!

driven round in circles on full RH lock at slow speed can hear see and feel a judder from front right wheel

Any help really welcome, I can’t think what else to look at !

Thanks in advance

Have you checked the Constant velocity joint in the drive shaft ?

I know you mention a donk but you also say it feels like binding, do you have the 4x4 info screen to show where your wheels are pointing or gap tool to check steering angle sensor ?
Just a thought may need to recalibrate The steering sensor or the coupling has moved / slipped

Hi all thanks for the replies

Yes I checked the ball joints and changed while driveshafts for different used ones, no difference

The car is basic spec, I do t have any screen showing where the wheels are , so don’t this it’s that

I’ll try the DSC later, but don’t think it’s that

Any more ideas please !!!

Many thanks

Are all your abs sensors working? I presume you have looked for diagnostic codes?

I’ve not run it through a diagnostic but the screen on the car usually Tells me if I have a sensor fault. I lift a ride height not clipped on the arm and it told me. The roads speed sensors are there and present .

As a matter of interest if I wanted an affordable diagnostic tool for the d3 what would you recommend? Is there software available to use with a laptop and lead. I had a free software to deal with the EAS on my old p38

I guess switching off dsc would eliminate abs sensors as a cause ?

Many thanks

Not sure on DSC solution. You will need to try. Perhaps record a movie of the issue and put it on youtube?

I have an iid bluetooth tool, and it’s great with diagnostic codes and live monitoring, not cheap though.

Ok update

Took the car out again this morning

Switching the DSC off or on makes no difference, no faults being displayed on the screen

Chasing the noise around the car I think it may be coming from the back not the front, it actually more noticeable inside the car than outside by the wheels

With the car driving in a straight line in 1st but at idle speed I get the a dunk about every second ( I reckon this is approx once every revolution of the wheel)

If I turn right (half turn of steering wheel) that rate of dunk increases to about 3 times per second, if I then correct steering left it disappears for a second or 2 and then starts again

I have noticed that it does it when I apply the handbrake at stand stil, but only the first time after motion

Could it be something to do with the handbrake assembly in the rear hub ?

Many thanks

It certainly wouldn't harm to do a parking brake clean up and reset per Bodsy's 'bible'.

I’ve ordered up a set of handbrake shoes and fixing kits. No idea if / when they were changed but after 350k I think a new set would be in order before I dismantle

Anyone have any other ideas please suggest

Many Thanks

So,

I’ve changed, adjusted and bedded in new handbrake shoes, handbrake working beautiful but still got this noise

While I had the back end apart I checked the rotation of the rear hubs, could not hear any noise no apparent play in the rear hub bearing all rear suspension joints tight with no play

The noise is most noticeable under 10mph and a lot worse when turning the wheel even half a turn left or right

The noise is accompanied by a jolt you can feel through the car

As a reminder I have fitted the Collins new parts

Front right hub
Rear handbrake shoes
Rear prop shaft

The following used parts from JOS

Front diff
Rear diff
Front prop shaft
Both front driveshafts
Rear right driveshaft ( had a split gaiter when I changed the diff so got a spare one)


New oil in both diffs and transfer box

Help !!
