PUMA rear diffs?
are there known problems with the rears? i am aware of issues with front diffs and we have certainly got through a few at work but havent come across problems with the rears.

i took my 09MY 110 XS utility (2pin std rear?) into the dealer to have the rear diff input seal done. when driving it in there was a rumble from underneath so i asked them to look at this too.

end result after they had spoken with LR technical was that they dont want to let me have the vehicle back and they need to strip the rear diff and send some pictures back etc etc - then i suppose they may think about ordering a replacement and then they may even fit it - i dare say a long drawn out process!

i know the 130s and later utility 110s come with a 4 pin rear so maybe it is a known issue - anyone lse had REAR diff problems? Cheers

I`ve had 2 rear diffs so far due to what sounds like a high spot on the pinion gear, you only noticed it at slow speeds. Mine has a 4 pin diff and its an 08 double cab Thumbs Up

Yes had a new Rear Diff 10 months ago in our 110 Utility 57 plate not sure if 2 or 4 pin, been ok so far. It went in a quarry and as soon as we got speed up on the road it was very loud and rumbling/grinding. Dealer got it sorted under warranty.

increased torque and lower gearing?

we had alot go on steep descents but they were all front diffs which with a fully loaded 110 and low 1st thats a lot of engine braking on a component. Cheers

Hi (remember i'm from Brazil)

- What is "pin", and "2pin" , "4pin"????

- How you can broke that much of LR diffs?????

Here in Brazil the jeep and toyota diffs are common, but the war CJ's and FJ40, not the modern ones, and all the LR diffs are much, much, much, much more strongest!! i'm impressed how tuff it is knowing my 09 90 CSW, I ask: How you broke it? Is it in off road? Or excessive speed/distance?

regards

2-4 etc pins are the "satelites" small conical pinions playing inside the carrier. Probably LR did not test them app with the new high torque engine. Puma 110" SW

markalpha I was lead to believe that they are 2 pin. The reason behind this was that's what I was told by LRCC. When I asked for the diffs to be up graded to 4 pins (I offered to pay the Extra) I was told NO by LR as it would invalidate my warranty as the vehicle is not standard Shocked Shocked Shocked I know I could not believe it either. However Ashcroft Transmissions has posted on this forum saying that the diffs are all 4 Pin.

Check out this link you will see an animated image showing a working 2 pin Diff. The red objects in the animation are what's called the 'pins'. If you were to add 2 more 'pins' between the existing ones you will then have a stronger 4 pin diff.
