2011 Defender 110 Puma 2.4 SW Keswick Green

Perhaps people who have experienced similar problems can all post their specific problem and how it was solved.
This way we can sort of build a library of casue, effects and solutions to future puma problem solvers.

My problems:

1. I get that rattle when free wheeling in neutral to a standstill. (This was not covered explicidly in this thread up to now). Possible causes I have gathered from others to be something wrong with Universal joints or something to do with the handbrake drum. ie transmition brake sticking?

2. I have the clunk in the rear of the drivetrain when shifting. (talked about allot in this thread). This it seems is most likely the rear diff or loosely fitted flanges on the rear prop shaft.

Can anyone expand on this?

Had a drive in a 90 yesterday.....NO noises. Also noted that perhaps these are due to clucth issues and not diff issues. When you drive and engage/disengage clucth without changing gears there is no noises due to roughly the same revs on prop side/gearbox side. THis to me suggest either clucth or syncro on gearbox issues. the diff noises are poccibly only a symtom due to the faulty clutch. Going in on thursday for a look.

This might be obvious but have you shifted the transfer box whilst moving? If so run in low come to standstill clutch, neutral, clutch, high, roll on gently might reset the transfer gearbox wind-up. I had a heavy knocking after a spin in low-range this sorted it and transmission and diffs now silent again.

Good luck, all this talk of replacement diffs is scaring me, only done 3k in mine and when it started knocking I though "here we go.." Above sorted it though

I'm not understanding you entirely. So I run run in low range and come to a standstill in gear with clucth depressed. Now I change to neutral and then change to high range and start going off gently?

I do that at least once a week just to work the box & linkages, no effect on the drivetrain backlash.

That's funny.

I went to N1 City on Tuesday and had the senior technical guy drive my landy. His first comment was 'this is one of the smoothest Pumas I have driven' - which totally bowled me over.

I then drove a brand new 90, and guess what? It made the same noises that mine did - gearbox clunking going in & out of 3rd, drivetrain backlash, etc.

So I guess this is a standard feature on mine and must just learn to shift more smoothly.

now what do I do?

I'm in 2 minds about taking it to LR Stellenbosch, 'cos their foreman drove my landy and said he also feels there's too much clunking in the gearbox.

But the last time I used them with my 110 Td5, they replaced a gearbox unnecessarily (when the problem was a propshaft) and forgot to put the gearbox cowling back, so not too happy about that.

u suck! but only because this has not solved mine

Going in for its first service in 2 weeks' time at LR Stellenbosch. At least the foreman there did concede the gearbox had an unusual clunk, so let's hope they sort it out.

I'll try the low-high trick again tomorrow and see.

I had the clunk and after spending the last 4 days and 500 odd kms off road, towing a heavy off road caravan in mostly HR3 and sometime LR1. I have noticed no more clunk since getting back onto the road and "normal" gears. Wondered what had happened.

Seems the clunk in allot of cases is transmition windup.....or possibly the inability to wind it down....
I still have the clunk if I shift like a lunitick. If I just take care to shift well the noise is 100% gone! I am so relieved. I was starting to develop trust issues with my new steed.
