I hear ya', but solving your own problems leads to a happier life which is more important (ps this is coming from an 09 Puma owner)...

At least you got a brand new t/c for nicks!

Fit an Ashcrofts ATB,cheap upgrade that will improve your vehicle on road and off and solve all your other issue's. Pat

My 09 Puma had a noisy rear diff and I replaced it with an Ashcroft HDP38 center.
That was even noisier, long story short I had my original diff center sent to a diff specialist who lapped it and set it up correctly. I think this cost about $350.
The diff specialist made the comment that the crown wheel and pinion and the bearings were all as new, not a mark anywhere. Vehicle had about 60,000k's on it at the time.
Now it runs silent and I am very happy with it, and quite prepared to just drive it and see what if anything happens.
As others have stated there are a lot of these diffs out there that perform well and give no trouble. It is easy to think the worst, as I did and spend a lot of money trying to fix something that does not necessarily need fixing.
I must add that even thought the Ashcroft diff was a problem for me, the service and attention from Dave Ashcroft was truly outstanding, he really went out of his way to see that everything was handled in a very professional and timely manner and I would not hesitate to recommend his service to anyone.

I'm on diff no. 4 in 2010 Puma 90. The first went at 10k; took me until 20km to get dealer to replace. They have gone at 10km intervals since. Early (until about 2011 were made in China; later supplied from Brazil) so depends when changed and what was in the system. Some were lapped in in Oz when the problem was at it's height in 2012.

Is it ok now or are you waiting for it to go again?

I'm at 66K new one only just gone in, car still at dealers with other issues so I guess ask again in 10K? The one they fitted at around 55K leaked oil on the way home! Car was just a couple of weeks from end of warranty which is why they were pushing back. I've held out although it took 6 months (after warranty expired) to get it in and the work done. My advice is be polite and reasonable, but be firm and persistent!

I don't know if its possible but can you just change to a salisbury?

Hi,
I've had four rear diff centres replaced on my 2011 110. Trivetts at Parramatta were as astounded as myself but this last one seems to be lasting well.
One thing I can say is that i ran the latest at no more than 80km/h for 500 km then changed the diff oil straight away, but this may have not been necessary.
The car has around 50k on the clock now and if it happens again I may go down the Ashcrofts HDP38 route, however, Les Richmond automotive in Vic. has decided to not use the HDP38 due to continuing noise problems, and is independently developing a ford based rear diff that will reduce ground clearance by 15mm, but is apparently bullet proof. I suggest getting in touch with him too for advice.
I really hope I haven't jinxed myself here. Hope this helps mate.
