Hi all
I need some advice with my 4 speed gearbox. Anything higher than 120km/h results in a vibration that starts to become worse the faster I go.
I asked my mechanic to check when I did the last gearbox oil change and he found that there is a play where the prop shaft goes into the gearbox. I also picked up that if I replace the seal here it only lasts a short time and then leaks again. My mechanic said that it is fixed by honing the gearbox and then doing something to get it back into spec. This will then solve the problem. I have never read on this site about you guys experiencing such things with your datsuns. Is this a common thing. He said it is quite common on rear wheel drive gearboxes.
