Thread: TD5 Driveline Vibration

Check the auto and transfer case mounts. I had the exact same symptoms and replaced lots of things.

Turned out to be the TC case mount. They looked fine from the bottom. But the trick was to undo the 15mm nut on the bottom on the mount where it bolts onto the chassis and jack the auto and TC case up. The crack through the rubber was evident, so evident it came out in 2 pieces.

This is a quick low cost replacement that may resolve you problems.

Something else I had noticed, the exhaust was closer to the auto sump than I was comfortable with, this can be adjust pretty easy though.

I assume the vibration has not been around since you bought it, if this assumption is correct then it is not likely to be the different drive shafts.

I have had the front driveshaft re-balanced and it was found with a small bend in it. Its a big mother and looks like it may have been replaced just before I bought the car, it is not a double cardan shaft type. It was also not in phase either although some people say that it should not be in phase as is traditionally done, so I would welcome some comments on that topic.

All D2s are designed to have a Double Cardan shaft, and I would think the angles of the diff pinion and the transfer output shaft were arranged to suit. The single cardan shaft is also on back to front although that may not affect anything.
IMHO , you should beg or borrow a DC shaft to see if that is the problem, which I think it is.

As said above, if the vibration is new, then the front shaft should be OK, if not, replacing the double cardan shaft with a single could be the issue.

But I'd look at what Jazzman suggest first, it probably needs replacing anyway.

Baz.

Have run a single cardan front shaft. Vibrated like crazy but I was grateful to have it when I needed it!
As said, check auto and engine mounts.
Also agree with PhillipA, get a normal front shaft.

I've had a v8 and now a td5. Both of them had an almost identical slight vibration/ harmonic around 105 kph.

This sounds worse but I'm just saying.

Good luck.

Remove the front shaft, lock the diff and see what happens.

I reckon the vibration is getting worse since my trip away in the weekend so I will pull the shaft off and try it with the diff lock in. This shaft was bent and Driveline Services straightened it and rebalanced it.
Has anybody experienced what a cracked flex plate feels like? just an idea, it still drives though.
Had a quick look at the T/C mounts, look ok.
