You can also check 3rd gear bush for wear.I dont know if this is the best way to check, but for the sake of a bellhouse gasket and throw out assembly gasket (if its the older model like I have) you got a good view of the internals.For those much more experienced than myself, please confirm if this is a silly idea. I hate for someone to take my comments as a way to do something when its not really a great idea

That's exactly what I usually do. The only problem is the "While it's apart I might as well...........

Haha - that went through my mind too and it wasnt an easy decision to just put it back together. Luckily I have another gearbox that ill rebuild and then swap it over.

I had my gearbox out for months and procrastinated about a re-building not having done this before.

Did all the visual checks etc, but it wasn't until I did a test under load that I realised the 4th gear bearing was shot. (gearbox installed and wheel up on chocks)

The cost of the new seals, gasket kit and bearing kit was minimal...all under $60?

I found the youtube video from the guy in NZ and set about a rebuild.

It wasn't that difficult once you got into it on a clean and tidy bench....you may need a bearing puller for the main bearing which I borrowed. everything else was relatively simple.

I didn't overhaul the transfer case....but ti didn't need it.

I felt much happier knowing it had been overhauled.

It still makes a whine in first gear....but I think that because its 55 years old!

It's allowed to!
Most of us who are over 55 years of age whine a bit every now and again.

Cheers, Mick.

It would have done that when new - they are straight cut gears.

That vid from the guy in NZ makes it look like a doddle to rebuild... but then again he has a super clean workshop and even clean hands! Very unlike me
