Cross8 clunk

[yowiie]

Sorry, delete reference to searching Ford forums. Their search function is rubbish … 'transfer case' will get 500 hits, 450 of which are irrelevant.
There are a lot of posts about vibrations, clunks etc, but no answers. The main suggestion is the '3rd bush' which is not a Holden thing.
As for you rotation movement in the front tail-shaft, it could be transfer case.

Maybe forum members with an Adventra could add constructive ideas.

I decided to get a second opinion on the issue, so went to Inverell to a 4wd place and talked to a guy that was holden mechanic, he checked all oils in diffs and transfer case which were good as I had already replaced them. He checked the driveshafts and he said that they were both fine.they had only slight movement and wasn't a problem
He took the car for a drive for half an hour and he is quite confident that its a gear box issue, as I mentioned earlier the clunk was only there around 60klms/hr and he verified that it only happens when its under load and going up hill. If its dropped back into 3rd the problem isn't there.
He suggested I put an additive in it which I did but it didn't change anything
So I guess I talk to an auto trannie guy and see what he suggests

As with all forums, it goes off track further down.

I'm interested in what your problem is, on the grounds that I hope it does not affect mine one day.
