Good prices too!
But they don't/won't deliver to UK addresses (in checkout you cannot get beyond the first step with a UK address), and so far they have not responded to my query about this.

I've rebuilt the diff using ceramic balls, resurfaced the diff rings, replaced the screw and the the lock nut. I've tried lock tight.... but I keep having the same problem.

Any tips of input on how to fix the problem I having would really be appreciated.

check the manual for the diff build,,there is a shim that goes between the diff bearings,,make sure it is there

That's what I use.

I'd try replacing the little nut in the diff half. That might have worn out. What diff grease do you use?

Get new diff rings. Clean everything with motor spray. And give it to someone who knows how to build a diff properly. And watch how he does it. But, it sounds like the same problem I use to have, which was putting to much grease on the diff balls. And the sound your talking about, have someone check to see if your belts are to loose.

The sound you are hearing is the diff slipping. Try to tighten the rear diff 1/8 of a turn and see if slippage is reduced.

I had the same issue and rather than going to thicker diff grease or finding some other means to reducing diffing, simply tightening the diff helped.

I just wanted to add a little more to whats been said about Tamiya diffs.
When they are built correctly they are as smooth as butta!, but if not re-built correctly they can be a real pain in the "AZZZZZZZ"!
Not only check the locknut but also the plastic piece that holds the locknut. Look very closely at them,some of them crack and get deformed from over tightening. I do a little mod to protect this piece. I put a washer between the plastic piece that holds the nut and the spring. This protect the plastic piece from getting deformed from the spring which can cut into the plastic or worse. I believe it also puts even pressure on the nut and screw.
I also use anti wear grease and replace the thrust bearing when you change the plates and balls. Hope I could be of some help!

Hey there

I had a feeling at my MRE:s original Tamiya servo saver is little flexible, so i decided to change it. I bought Kimbrough servo saver 25 spline drive # 114 because i use Futaba s9550 and i think it`s better to use saver anyway.

I`m not visit track yet, but is that ok, or what saver you use with that servo?

Thanks

Tamiya servo savers are well known for going sloppy very quickly. For all their expertise, why they have not come up with a better arrangement is beyond me.

I use the small Kimbrough servo saver that is specifically made for Futaba servos. Works beautifully.

I had a problem with the Tamiya diff, it kept coming lose. The problem I was having is the locknut would spin inside the plastic locknut holder as I tightened the diff screw. I race at Tamiya's track in orange county, Fred Medel of Tamiya gave me a fix two years ago and I have never had a problem since:

Place a drop of CA glue in the placstic piece that holds the diff locknut, it will keep the nut from spinning as you get to the desired diff tightness, it also helps keep the plastic nut holder from cracking.

Good luck, I hope this helps.
