doriftu,
I used AW grease on the diff plates and 3mm balls. However I first sanded the diff plates to make them flat and I used Much More Thrust bearing grease on the thrust. I changed the balls to the carbide 3mm Tamiya balls.
Make sure you do not over tighten the diff nut. I have already stripped a 2mm locknut, split a thrust bearing and snapped a screw.
I am now trying some other Tamiya parts in the MO5 diff, which are stronger.
Later,
Calvin.

sidecarphil1,
I have found the screw is not the problem,(unless you really over tighten, then snaps) but the inferior 2mm locknut is the cause of the problems with the Tamiya and 3Racing MO5 ball diffs.
I have fitted two locknuts into my 3Racing MO5 ball diff and will give it a try. I am hoping that the extra nut will give more purchase area to the screw and prevent stripping.
On the Tamiya ball diff I have removed the nut holder and replaced with the 416 diff screw mount and applied loctite.
I am testing these to see how durable they will be. I am only tightening my ball diff until I can not move the diff gear when using two allen keys.
When fitted into the car the diff feels slightly tighter than a gear diff, however does not slip.

Hi guys
Since I'm not getting to run much right now, I'm selling one of my Minis.
This is my new M05 PRO that I built for the last round of our series.
It TQ'd there, so it can't be bad !
Only other runs it has had is a couple of practice runs at the club, all on carpet, to set it up.
Will come complete, highly specced, lots of hop ups.
stuff like ; ball diff ( + parts to make geared one too)
Tamiya M chassis alloy shocks
steering link changed out to 3R one.
all good stuff.
KO servo
GTS Speedo
motor
no receiver as I think I'm the only one around here running 27FM !
Large spares package.
box
manual
body shell
and anything else I can find that I think you might need
looking for around $300CDN
thanks
Stu

Hope i am in the right section here but i have a small question for you guys.
Will the Alfa Giulia Sprint GTA body fit the M03M???
If so where can i buy a replica of this body if it is been made.
Looked on Fleebay but you hardly see the body there,only the complete car and that is a M04.
cheers and thanks in advance Roy

I've received a set of Muchmore Sweeps (25s) pre mounts with soft (pink) inserts. Can anyone offer advice regarding running the M05 on the same inserts all round on carpet?
Should I glue them up and run them or is that asking for trouble and I should swap the fronts out for a medium insert?

Do you know what the Tamiya part number is for these aluminium spring perches? I have been looking for some for my TRF dampers (42102) but can't find them. Any help is most appreciated. Cheers!
