Jon uses nitro gear stuff on his diff rebuilds IIRC Clive, might be worth a note to him...
Thanks for that Gav, I'll drop him a pm.
I went to see the truck today, and the Nitro shafts and birfields they propose to fit.
It's very strange, I had misunderstood what the problem was, when I lost drive, but I understand it now. I had assumed they had found a broken shaft, but the truth is, the RH birfield had lost its balls
They were scattered about in the grease and with me driving it in that condition, the center part of the joint having a bit of a hammering with no balls to protect it from impacting the outer, has damaged the spline on the driveshaft. There's play now between the driveshaft and the birfield center, so their advice is to replace both the shaft and the birfield. I'm doing just that, on both sides. New Mr T rotors too. The birfields on my shopping list are quoted OEM parts, in the Toyota box, not after market. That's why they were so expensive, about £480 each....
The nitro birfields look nice, but they would. All shiny and chrome looking
The other bit of news is they've found me an axle casing. For years I've known I've got a bent casing, giving me a slight Hillman Imp ish positive camber on the RH side. It's about 1 and a half degrees out from the laser measurements I had done some time ago.
An empty casing is going to cost me about €300 so don't tell Karl, he says after strip down, he throws the casings away for scrap
Pricey, but it will be great to have upright wheels again, or at the least both wheels at the same camber angle. He's also going to check the front diff to see if some of the backlash can be reduced. I've got about 5 minutes of free play in the prop flange, but I don't know whether that's in tolerance or not.
I had a good chat with the guy, he's very knowledgable and interesting to talk with. He's got a bobbed 80 that's his favourite comp off-roader. It's an 80 chassis with a home-made body, short and high with some monster shocks on it. They must be 6" in diameter

He's also got a 70 comp truck which is bobbed as well. He says there's 6 donor 70s at his place, the parts are so hard to get, he's been buying up knackered second hand trucks as donors.
Looking forward to getting the truck back...
