Who's had problems in these areas, because Gracie still has, despite the input shaft being done, quite a fair level of backlash/slack/clunking, which I thought, from reading about various driving experiences of far more experienced Defender owners than me, was "Normal", but,.....IS IT?

Hi Pickles,

Yep 1nando has a good suggestion, now that the rear shafts on mine are new again, the HD flanges is something that I'll be looking at.

There's lots of threads/posts about the flanges, if they're not too bad then they can be greased which will make them last, otherwise replacing with the HD flange seems to be the way to go.
I think dazzaTd5 has posted about the flanges before, it'd be worth searching for some of his posts.

Definitely get the HD flanges & new rear half shafts, it made a huge difference on my TD5, but sadly won't work on the Heritage as the HD flanges are a bright goldish colour - can't hide them under the boost wheels! I will just change the standard flanges on an as yet to be determined basis. I keep a set in my spares kit for the Series 1 as they have similar issues.

I suggest you invest in HD flanges all round. If you can afford to do your rear axels at the same time it is recommended.

This is in my opinion a must upgrade on every puma. My opinion as a result of my experience

Definitely do the HD flanges. That alone took an amazing amount of clunks and slop out of my Defender's driveline. Mine was still only at ound 10,000km IIRC... And so didn't change the half shafts.

I was assured the new one had been greased!

I pointed out to them the rapidly deteriorating clunks from the rear but was still pleasantly surprised when they said 'yep you're right, so we've replaced them too!'

Great stuff from ULR!

Time to visit Melbourne then! :D

Sound familiar? From Explore Oz 2004. We are not alone...

"Hi...Just wondering how many people are having problems with the new gearboxes in the 78/79 series cruisers..I had mine strip the intermediate shaft @ 110000 km-(Was stuck in the bush and had to be towed out by a commodore)I'm no expert but the intermediate shaft has only about 20mm of spline connecting the gearbox with the transfer case...looks damm flimsy to me..the only warning I had was some backlash in the driveline...The thing that annoyed me was that I rang the toyota helpline and a dealership and they said they had never heard of problems with these gearboxes-but when I contacted a non genuine dealer here in WA he has the intermediate shafts on the shelf and they were selling like hot cakes.......The only two other people I know with 78 series cruisers had gearboxes replaced a 60 and 70 K...100% failure rate out of the three I know of seems poor..I've Emailed Toyota twice and no response..."

At least it sounds like ULR and others are doing the right thing re Defenders.

Ummm,just sounds like Toyota, when we did a diff in one of the work vans.The dealer was like'well its just out of warranty,we don't want to know,and i have never heard of a diff failure ever'.And that van was serviced at the same dealer,since new.

A quick look on a couple of forums,and there are heaps of issues with the diffs in those particular vans,noisy,failures,etc.:mad:

Agree,LR generally do the right thing,my experience with 5 new LR's over the years with warranty issues has been better than excellent,even though the vehicles have been serviced elsewhere.:)

If you are interested, I can take a HTE (brand name) drive flange and screw on cover to the place that does all my powder coating and ask if its possible to powder coat them and the durability of doing it.

Yes I'm sure I've covered the clunk clunk Defender TDCi issue a number of times in posts

If I havent already spammed this....
https://www.youtube.com/channel/UC0g...Uwpq2Qivaj_wbg

two short vids of axle / drive flange free play at 10K, 30K I think from memory

So to summarise, clunk clunk in drive line on Defender TDCi...
*Axle / drive flange free play.
*Centre diff preload poor or excessive wear.
*Adapter shaft wear.
*Clutch failing, mostly 2.4lt, but seems 2.2lt are starting to suffer.
*Poor driving technique.

Regards
Daz

Toybota's have had this same problem since the 60 series,I had it happen twice on my LC's,the rear drive shaft is also a problem,it starts to vibrate back up through the gearbox and Mr T's fix is to simply pack the spline with grease to dampen it. Pat
