    NP or NS? Ther was a problem acknowledged by Mitsubishi where the companion shafts actually seperate slightly from the diff and then leak around the seals. Mitsu will replace the companion shafts with ones that have a better retaining clip. I am told that they should do it as a no-cost recall however I had to pay. Cost is about $260 per side.

      Didn't want to start a new thread as i have a similar problem with my '08 Paj.

      The car has done 83,000kms and absolutely no towing at all. 10-15% off roading in desert sand dunes and no rock crawling too. I recently (a week ago) changed my wheels from 18" to 17" and got michelin latitude tour HP tyres in 265/70-R17 so got a wheel alignment also done at the same time. There is a leak from the rear diff at the right side companion shaft.










      It seems unreasonable that at only 83,000kms the seals are leaking. We only have 60,000km warranty so i'm not too hopeful about any positive response from MM but i'll give it a try.

      Is it just a matter of repalcing the companion shaft seal OR does it need the whole half shaft to be replaced ?

        In mine(2002), and some of mi friends (2001), happens one or two time in each car in almost 200.000km (in mine firts time at 70.000 in left and second time at 120000 at righ) without towing, and we only change the seals, and works fine. The seal it's so cheap and not to hard to change.

          That leak pictured is a seal leak not a popped companion shaft. So it will just be a matter of replacing the seal, no new shafts involved unless your shaft has been scored/worn (which I think is highly unlikely). However I believe it would be prudent that if removing the shaft to replace the seal, you also replace the c-clip on the shaft, to be sure, to be sure. Both parts relatively cheap compared to a full shaft replacement.

          The seal itself is a radial lip seal with an additional face lip that mates with the companion shaft flange to stop crud from damaging the main seal. I suspect crud can sometimes work its way past this lip. Once past the face lip, it cant get out. Sand may be a big culprit due to its size and abrasiveness.

            Thanks a bunch Enric & Shane. I have some peace of mind now. Gotta love this forum . What i'll now do is fill the diff with gear oil to the proper level as i'm not sure how much has been lost by the leaking seal, and then i'll take it to my mech for replacing the seal+clips on both left+right side axle on the rear diff. Does it make sense to do this replacement (seal + clips) on the front diff as well ? preventive maintenance ?

            So, i'm looking at 2 x Rear diff oil seals and 2 x Rear axle drive shaft clips ? would that be part nos. MR410469 (clips) and MR350883 (oil seal) ? or are there new/updated part numbers from MM ?


            thanks again guys.

                Do you have a link to where you bought those seals ?

                  I'm from Spain and I bought it in England in Milner offroad.

                    Vicks, I had the same diff seal fail at about 50,000km. Replaced under warranty by MM no problems or difficulties.

                      I got new MM seals (equivalent of 20AUD each) and installed them 2 weeks ago. Washed off the oil from the diff housing & axle and till date there are no signs of leakage. Also changed fluids in both diffs & the transfer case as it was due.

                      Thanks gents for all the advise & help.
