Thread: D4 transmission clunk

.......... would give you enough to read until Easter .................

This was a common problem in the D3 (I had it) which was mostly fixed with a software patch. I don't recall anyone with a D4 having the problem and I don't for sure.

I was going to do a google search on this, my D4 has 10,500km on the clock & I've also noticed it. The heaviest thing I tow is my 6x4 box trailer with rubbish to the tip, but I only notice the noise on & off the throttle at low speeds.

The clunk sounds very similar to the driveline clunk I had in my defender before I changed the rear axles. I hope it's not anything like that I doubt it would be as easy to change & as cheap!!

I just figured a bit of driveline slack must be normal? Mine's done about 24000 km...

I've only had experience with worn axle splines, do the CV shafts even wear like that?

2009 D4 SE.....I've had it from new, comes on when I've been giving it a bit of welly and then back right off.

50K now on the clock and hasn't got any worse.

Happens rarely.

Cheers,

Kev.

Gday...

My mate's experience -

· Last week (mid-October 2011) while driving to Melbourne, I had to go off the freeway into Morwell (after about 100km on highway that morning). As I slowed down there was a distinct “clunk” and a shudder through the car. Rolling the throttle on and off, very gently, repeated the clearly audible noise and a shunting that could be felt – definitely something loose between the crankshaft and the Rims! Fortunately this happened within 500m of the only Land Rover dealer in Gippsland, otherwise, I would have been stuck and the D4 would have been on a tow truck again. In this short distance, the shunting and the noise became worse. After a very short demo drive with the Service Manager, the D4 was put up on the hoist and the front mount on the rear diff was tightened. From the Service Manager's feedback, this Nut/Bolt was never tightened during assembly and hence had taken 25,000km (purely road driving) to work its way out from Finger tight and in the next 100km had worked to be almost fallen off. Fortunately this didn’t happen in a month’s time when I’m going into Wonnangatta (although after this experience, I’ll revert to a day trip on the KTM!). The Dealer was very helpful and had me on the road in about an hour, although the breakdown caused me to miss a meeting in Melbourne and delay a flight.
Just for interest concerning "Clunks" in D4 driveline.

Christ could it be that simple?? Sounds like the oil pump gear issue I had to fix on my Td5 with lack of loc tite on the bolt from the factory.
