Rear diff for lunch, anyone? *munch* *munch*

[elnevio]

It's worth a go, but the diff will be open to the elements until the drive shafts are fitted, so the potential for contamination to the new oil is high, at least with an empty diff if you do get any crud in the seals whilst fitting it you can clean them with petrol/diesel/brake cleaner/mr muscle/channel No.5 without diluting the oils.

oh and good luck gents

Thanks for the info.

Team CVR4 to the rescue. No other club has this type of response, 41 post in 20 hours. Diff sorted, pit crew sorted. Well done guys and good luck Nev!

Definately interested in how this goes seeing as it now looks like I am going to have to change mine in the New Year

Oh dear! That doesn't sound good

The noise that I had at the 'Ring came back this morning when I hit the loud pedal mid roundabout despite having changed all the fluids at the weekend. It only happens when turning right and giving it some stick. I noticed from an old thread that you had some issues with it but they were resolved with a flush and clutch pack fluid change?

I am assuming it's the diff at the moment but I don't know for sure. Mind you, I am not sure what else it could be.

I had the very same problem with mine and me mates from mitsu initially thought it was a propshaft issue but after closer inspection, they noticed very minimal play in the driveshaft (to the wheel on the inside of the turn). It never got worse over time tho.. and so I never swapped out the shaft to see.

When were the oils last changed Wayne?

[foxdie]

Hope you can sort it without breaking the bank mate

Saturday.

That's interesting, Pezza. So, they thought it was the driveshaft at fault not the diff? I have not checked for play yet so perhaps I should.

When I first got it, basically fresh off the boat, it had a bit of squeal when turning left under power ie coming off a roundabout, which sounded like tyre rubbage. Changed the oils and it was OK after that. Changed them again after 2K and then every 4.5K.

Tyre rubbage, yes it does sound very similar to that. But, quite severe rubbage at that. Interesting that you had an issue on left hand turns and now it's on right hand turns hmm.

Anyway, I wonder how the CVR4 pit crew are doing ...

Down the pub by now I expect?

[Mrs B]

Um..... they are still here - outside in the cold.

[Roberto]

They sure are commited to the cause, fair play to all.

[ANTHONY]

so how mant other members card has this happend too........................oh and bad news nev but looks like you have it hand

[Adam.Findlay]

Yeah man know how you feel. same thing happened to me, just cruizing slow and VERY LOUD NOISES. then a large oil trail as the diff had smashed itself.
im real guttered that i never got pics of the casing before i turfed it because it was real impressivly smashed.

[elnevio]

Well, the old diff is out. Eventually...

We have learned something about removing the diff - and that is that Mitsi engineers didn't have a lot to play with when they 'designed' and fitted the 4WD system / VR-4 combination!


MASSIVE thanks to Turbo_Steve and miller for helping out - more than one person for this is really REALLY useful. Unfortunately, we gave up as the two rear bolts haven't quite aligned, so are now proving practically impossible to put back in - meaning that the three bolts on each side will need slackening/removing again. One of the lessons learned is to do the rear bolts back up first!! The reason we gave up at that point is because it was past midnight, and everything outside of a 3 foot radius of the halogens had iced over! Brrr!! So, I have that to finish off this afternoon, but the hard work is out of the way. I'll just be grabbing an assistant to help me bleed the AYC when I've finished realigning all the bolts, putting everything back together, and refilling the fluids later on.

In the meantime, I will start a little story regarding the old diff.


Before removing it completely, thought it would be best to drain the gear oil out. Undid the drain bolt, ready for the torrent - and got about three drips of red/brown fluid. So it appears that the ATF and gear oil had joined forces in their successful escape attempt (i.e. yes, Brad - there was definitely red in the gear oil! )!

Anyway, the drain bolt appeared to have little bit of swarf on it:

Got a better look at some of the cracks in the case:

Remember those pushed out bolts? Well, they seemed to have taken their own little momento from the case, in the bolt threads:
