Thread: Replacement Puma diff warranty terms

It was fixed again and was great for ages but has started to whine again..we have also had a persistent leak from it.

I'm not going to be ****ed if its a tailshaft I'm not the one spending all the money on it...

There is also a none quality issue with crown and pinion wheels whether they have that isolated yet or not I don't know

Sounds like the pinion seal is rooted and a lack of oil has caused a bearing to sieze, how bad is the leak?

Nab it's not that the leak is not bad enough for that the leak on my rear pinion was worse... Besides the leak came back after the whine.

Hi Dullbird - Just thought I'd wade in and let you know my Diff is getting done again next week. First time it was a whine after about 90km/h or so.
Came back after being reconditioned, and it now whines from 40km/h up. Loud enough to not be able to talk over over about 70km/h....

yeah been there done that....dealer is trying to obtain a new diff for us rather than rebuilding for a 3rd time

got a line on what the cause might be......

found out when an appy was trying to set up a diff and couldnt get a whine free diff...

the spacer block for adjusting the zero of the DTI used to measure the pinion height is now 2.1-2.2/1000ths of an inch undersize so he could never get the initial pinion height correct.

Might be an idea to get whoever the diff specialist is thats doing the diff to ensure that A) they are using the right pinion block for the relavent diff (the p38 style is different to a rover but both are listed as a rover diff pinion block) and the block is manufactured correctly.

Good luck to them DB, last week there were none avail in the country

I just salisbury converted a 2005 110 due to screaming /pinion failed/ rear differential.

Very poor quality crownwheel and pinion hardfacing is my guess. It was howling for only a week then the pinion bearing let go and started to leak possibly due to being immersed in metal particles from the crownwheel face etc. This vehicle has done 130K and AFAIK is its first rear diff failure. Anyway, it has a REAL diff in it now so no need to worry anymore.
