Not all bearing needs to be changed. Do some research and decide what you want to do.

Read Zuk's write ups as he does amazing job on gear installs.

Also you can source Aftermaket install kits from a lot of vendors like Cruiser Outfitters and Justdifferentials and etc. Just an option to save few $$

Sorry, but what does that mean?

never saw 'em before .. kinda skeptical about that ..

You never saw them because they were mainly available only in Europe with 5spd

Thanks for doing this Akella!

Since I'm planning to use gears from a 60 series third member for the rear to keep cost down, will I need any additional items?

You won't be able to match the gearing exactly with 60s in the rear.... 3.70 vs 3.73

Crap, is that way out of range or will it work? I've got a part-time setup, so the front will only really see use off-road.

 

[davegonz]

I think it will still work. If I'm looking at it right, it's less than a 1% (.8%) difference between gear ratios.

yes indeed they will work ..

 

[Fromage]

Less than 1%? I would rock that like a hurricane.

Dave, you have to do this.

 

[davegonz]

Gonna rock it!

3.73 gears for my front locked hi-pinion diff! Thanks Akella for sourcing these!

Very nice. That'll drop the RPMs a bit

that's really nice ..

 

[Workhorse]

Any update? Dave, did you get these installed and running? Update on the change in RPM, fuel mileage, etc.???

Thanks in advance for the information Dave!

 

[Workhorse]

Any updates to report on the 3:70 gearing?

Thanks!

Gob I love beautiful Aichi metal!!

 

[scuba steve]

Subscribed!!!!! Super interested aswell.

I've been slacking and haven't regeared the front yet, but I did do the rear (part time 4wd rocks). The RPMs are down on the highway and I don't think I lost much on low end grunt. I'll get the front ones in when the temps cool down around here and will post up the results.

I've sourced a few parts fro a yard in UK, Says he is the biggest landcruiser yard in the his email is garry@80breaker.com
I was there in July and he had 14, 80 series waiting for breakdown. I nearly slipped in my own drool.
