This weekend I will tighten the out put flange nut to ensure this problem do not pop back up.

Steve,

Can You describe Your reply a bit more in detail? I´m not sure what bolts that You mean and it sure sounds like something that I should check on my car.

Thanks,

Steve I have never seen this nut. I plan to take off the Four bolts to remove the driveshaft from the flange and maybe remove from the diff too. I trust that when I get there I will be able to see the nut. Then I plan to stick a socket on an impact wrench and tighten things up abit.

The nut could very easily require a special spaner socket. The new nut will tighten with a 12point socket but the originals were round with four slots. I have seen many tightened with a chiesel and hammer.

The nut holds the output flange to the output shafts and doing so squeezes down on the output bearing inner race the governor the speedo gear and a few spacers (most of which is inside the trans.

It will require dropping the front of the driveshaft out of the way.

The spanner socket driven nut explainse why it is loose. Brownaie, either get the socket or the replacement nut before you pull the driveshaft. A new hex nut seems to make more sense.
