Builds 1979 FJ40 Preservation-ish Project

8/80 + rear axle would be ideal! I am assuming they would be hard to find.

FJCO Sells bolt on adapters for $500, or you could make them yourself pretty easily with your skillz

Or narrow a FJ60 axle, again pretty easy with your skillz

I am now fully committed to a stock axle rebuild on this truck.

Only question now is do I powdercoat the axles and components?

My dad is rocking the FJCO drum upgrade on his 78, cool solution but not the road for me.

I just noticed that a rear brake cylinder is leaking on my fj45 shop truck. That truck is going to get converted to rear disks. It had been previously updated with 1978 axles.

 

[OPMACHINE]

I have got the rear axle stripped down, minus the 3rd member and the backing plates. I am trying to determine acceptable wear tolerances on the thrust washers and the pillow block shaft. Anything else that is typically serviced or inspected while I am in there.
- Going to replace the universal joint on the drive shaft.
- Probably going to pull the fuel tank while the driveshaft is out.
- serviced the transfer case output seal and parking break.

The shaft has some visible wear, the thrust washers are polished and smooth. I am trying to determine if these should be replaces? Can I still source OEM thrust washers and pillow block shaft? (I have not found the correct term). Tonight I will grab a beer and read the MUD and the FSM to get my answers.

Salesman mechanic trick to avoid reading a FSM ever…..

Put the front diff in the rear. It’s basically new on 98% of US 40/55/60s

 

[OPMACHINE]

This is a trick!

I should have planned on rebuilding the front axle at the same time. I could probably finish both axles before Christmas. Skipping the powdercoat would sure save some time.

Rear axle is prepped for blast, etch and powder coat.

First attempt at removing the u-joint with a socket and hammer failed, I guess I need a u-joint puller

Toyota joints are a pain. I take them to the driveshaft shop

Pretty easy with one of these.

 

[OPMACHINE]

That is what I ordered. Glad to know it will work. Took me about 20 min to scrape the grease off to find the c-clips.

 

[OPMACHINE]

My wife thinks I am working late, but in reality I am trying to get ALL the grease out so I can sandblast.

Did you like the u-joint press?

I'm a little late to the party to be useful on this but I don't bother pressing out ujoints anymore. I torch all 4 of the crosses in half, basically cutting the arms from the center...I then use a air hammer and drive the caps in, to the space previously occupied by the center of the joint and they drive out like a hot knife through butter. It works awesome, I've never had it fail me.

 

[OPMACHINE]

The puller worked as advertised. Took me about 20min. The torch method seems equally effective, but I would have to work myself up to the torch.

What are you guys and gals using to secure the hard brake tube to the rear axle?

Toyota P/N: 90480-08343 is discontinued

 

[cruisermatt]

If you didn’t already find out all the rear spider gear components are available new
I’d love to buy a few of those diff plates?

Brake lines - adhesive lined high ratio heat shrink

 

[OPMACHINE]

I have ordered the spider gear thrust washers, but not the actual spider gears. Better to replace the spider gears at the same time? I have been a little concerned the old spider gear and new thrust washer would not mate/ wear well together. I was also planning on swapping the front and rear 3rd members.

Heat shrink is a great solutions! I just tried to order 90480-01069 brake line grommet, we will see if it is actually available.

I am new as scouring the internet for Toyota parts, @OGBeno had me spoiled. Takes me forever to get my parts list together and I can never seem to order everything I need at the same time.

 

[S.CarolinaFZJ80]

You could probably use two separate rubber bushings/grommets for the rear brake line bracket.

I think two small bushings, similar to the spring eye bushings, placed end to end from either side of the bracket, might be a good solution if you can't find the actual one.

Maybe @ToyotaMatt could reproduce this bushing???
