Thread: D3 vibration/shudder/noise

Can't be too careful.
Simpson in1989 in RR classic with 44gal petrol on the roof and a family of five did one front spring (carried a spare) and clutch master cylinder (convoy carried one). Otherwise trouble free in 160k.
Dico 1 all over the country no problem in 120k.
Disco 3 fro Melbourne to Cape York did in two front steering bushes, one turbo return hose and had to replace its second suspension pump. Luckily on that trip service was not too far away or problem did not stop us.
Otherwise I've only had the problems everyone else has had. But I love the car!

Urgh. Looked under the car today, mainly to check the propshaft, and I didn't quite expect to see the transfer case like this. You can't see from the the pic but it also looks like the propshaft has been spinning oil near where it meets the case. I wonder whether this is my culprit.

Off to MLR today, should know by wednesday what my problem is. Hopefully simpler than transfer case bearing seal.

That looks like an annoying issue Morpheus. Be interested to hear if it is the source of your vibration. Looks like a bearing seal ... And they look to be a pita to rectify.

Do you know if this leak was present when the diffs were done ?

MLR helpful as usual. Checked the drive line and all and did test drive.
Was the roof rack as I first suspected but SHMBO disagreed.
Cheapest but rumble continues.

Mick - there was a slight bit of weeping, but nothing to write home about. The service I had done recently (a major) did not even raise it as an issue.

Mechanic and I took the car for a drive (for about half an hour!) and we have traced the noise to the transfer case. However, we also picked up a wheel bearing noise (when cornering), so this may have been where the problems started. The car is going in for a proper inspection on Thursday so they can put it on hoists and run tests.

Will know more on Thursday and what I am up for. The Minister for Finance, War and Torture is not impressed.

My rear diff was weeping slightly in the lead up to the commencement of rude noises and subsequent replacement.

Front wheel bearing ? I'd say do both, the other one won't be far behind.

On the bright side, once you get that sorted it should be all good - there are only so many issues you can have and these are normal age/weight/mileage related problems.

Good luck with the Minister for Buttkicking - I'm lucky that mine is fairly understanding of such things (and it helps that we always have at least 2 working cars) ... although she has still not quite forgiven the one and only time it ended up on a tow truck (wheel bearing) ... let us know how you go

Better pics of the rear propshaft. You can see the oil spray marks on the underbody of the car.
