I am shaking my 38 down. No longer drops out of top gear. New problem. After about 100 miles on the freeway I arrived home to find oil on the inside of the LH rear wheel. Now that has come all the way from the transmission. I drained the excess from the differential which came to 1/2 a pint or 1/3 of the transmission capacity. I have read up and see that I need to replace the front tailshaft bushing which can either be the original style or an "Oakie bushing". The former is readily available in Australia but the latter would need to be imported. Is the original type satisfactory or is there a great advantage in the Oakie bushing? At the same time the rear axle oil seals are obviously not holding back the oil. Would replacing these seals cure the oil leaks onto the brakes though obviously I would need to monitor the flow from the transmission? Thank you.

Hi Terry, Actually, the original bushing and seal worked well. After many miles the bushing would wear. The correct procedure is to remove the rear end and replace the bushing and place a new seal. This was a lot of work so someone invented the "Okey Bushing". It was for use by the lazy owner. It is strongly recommended to remove the rear end, replace the drive shaft bushing and place a new seal. Replace both axle seals and replenish the oil in both the transmission and rear end. Should solve your problems for several years.

Hi Terry ,
How did you fix your gearbox to prevent it popping out of top gear?

Hi Terry, I disagree with Ray's comments on "laziness." Because there is an easier way to do something doesn't mean you are "lazy" to do it that way. Maybe it means it is a whole lot easier or smarter. In the case of replacing the front bushing and seal of the drive shaft it is a hole lot easier to do it with an Oakie Bushing. The problem you may have is that the Oakie Bushing for your year may be out of stock from our traditional suppliers? Do an advanced search on only the word "Oakie" and search the last 3 to 4 years and you will get a good understanding of the whole process. Good luck, Mike P.S. Here is a start.

To answer jack's question. Basically we noticed that the input shaft had been cut short so a new input shaft was installed along with new sealed bearings throughout and a new spigot bush. We also installed the best of a selection of universal joints.

Ray,
I would like to know the recommended procedure for adjusting the gear lash when putting the rearend back together. I have seen opinions that the shop manual method may not produce good results with a gear set that isn't new.
