Thread: "They all clunk" True or False?

My 2.7 D4 clunks when accelerating after the engine revs drop back, particularly when braking to go around a round-a-bout then accelerating before I come to a stop. The engine management does a pretty good job of holding the revs up after your foot is off the throttle but not all the time. If i feather the throttle on however there is no noticable clunk.

My dealer looked into just after I got the car and at the last service. They were going to put some microphones on the diffs and transfer case to isolate the noise but the unit was broken when I last had the car serviced.

If you hop under the car and rotate the drive shafts there is backlash either side of the transfer case, but this seems the same whether the car is new or not, since I got under one of the show room cars and it was the same. This explains why sometimes I can hear the clunk up the front and others up the back.

So I'll see what the dealer decides when the listening device is fixed. The D4 still drives like a dream but the clunk just gets a bit anoying at times as my engineers ears hear everthing. Once I go deaf I'll be fine, but at 39 I've got a few years to wait. My wife never notices the clunk. What's up with that?

Well actually it will. I like a challenge. If everyone else has the problem, I can live with it too - because the D3 is otherwise a brilliant 4wd. However, the inconsistency of reports is already apparent and I would like to find the reason for that - and so should Landrover. They should all leave the factory with identical characteristics, wouldn't you agree?

Well, after driving my '95 Deafener for 15 years I can barely hear a gunshot but I can hear the clunk. My wife, on the other hand, has 20/20 hearing and she reckons I am imagining it.

LR don't give a toss.
Apple Corp don't give a toss . NO ONE gives a toss ; that's the
new standard in industry and service.

2005 D3 with pushing 200K on it, yes you might get a clunk under some conditions but not during normal on-road driving. In 12 months I have probably heard 'clunk' 5 or 6 times.

D3 MY08 model. I can get the very occasional clunk in the right condition. Ie. Braking to a very slow speed, and then accelerating heavily without feeding in the throttle.

Nothing like the backlash in my (ex) Range Rover 86 model. Either way I very quickly adapted my driving style to cater for it so that it almost never happens. Not done as a conscious thing, but an unconscious adaption of driving style.

Bugger ...Bugger! ... I have missed out on this and that stinks!

I have no clunk that I can hear! ...I think I'll complain to LR why should I miss out on a clunk when everyone else has one?

Maybe Neil you could assist me get LR to fix my D3 so it has a clunk.

cheers,
Terry

I have a clunk in my 06 TDV6 and was wondering if the clunk frequency can be changed to the same as my wifes voice then it will be fixed
