hello, I have a problem with my T3 back 4'77 is the second set I and breaks up the metal does not stand up???? Have you ever had a problem.

The bearings are in good condition and adjustments as an idea!

Exactly the same.

I did built a pumpkin in winter and bolted it all together in febrary. Was excited and went did the brakein proceadure. 500k's later noise. Since then i did 4 rebuilds and brought the pumpkin to roth racing. Wasn't better, because i had the exact same symptomes like you. They told me, that they tried the best, but it wasn't quite.

Now this week after a long motivation loss and many hachiroku-destruction-attempts i'm going to take the pumpking down again. I have a new TOYOTA 4.8 r&p and a new pumpkin ready to be assembled and this time the guys at roth racing will bring it to an end!

Ask Roth Racing in bern region, they are cracks on ae86.

As I see you had a bad pinion height set up! The teeth didn't contact at the "middle" And other idea is you didn't use solid spacers, the third is just an additive, there was not enaugh oil near the teeth - maybe you drifted (or tracked?) long time at one direction and the oil went away.

We used to over fill the rear axle and upgrade the breathing it helps a lot for the final gears.
