Thread: Life of Puma Rear Diff's

Hey Iain,

Leaving on Tuesday 30/7 heading for Broken Hill.

Then onto Tibooburra, Cameron Cnr, Inaminka.

Not sure what day we will arrive as we just going to take it easy and enjoy the sights on the way.

Would be great to catch up somewhere if it works out.

Just thought I'd give this thread a bump to see what transpired with the Ashcroft HD P38 type replacement diff.

It would be good to hear any reports of how people are finding these as some must have clocked up a fair few km now. OK so the locker probably works and gives you heaps of traction (you'd be disappointed if it didn't) but what about the noise issues that were being reported. Do they 'bed in' and become quiet over time or has removal and machining been required? Also what is the source of the noise, is it the gear profile or something else?

Anyone got some experience to share?

Thanks,

Ian.

Recent inquiries with a (large) local dealer indicate that the issue remains unresolved...largely because the source of the issue is proving elusive.

Having said that, I'm aware of at least one example that is operating reliably and silently.

I have a heap of km on mine (just over 10k I think), it has been re-lapped and the noise is still there.

Otherwise great.....!

I have done about 12K on mine now and can report that it is still silent and smooth as ever under all conditions. Engages and disengages without any problems or noticeable noise.

Only issue I had was a leaking pinion seal which was replaced immediately upon noticing it under warranty.

I've got 7000k's on mine.

Still the same small whyne on de-celeration 60k's to 40k's, really not a big deal, not even sure I would pull it out once the cause has been identified.

Very smooth, engages/disengages with ease and provide confidence that ts not going to break !

No doubt Ashcroft's will sort it.
