More SOA Q's before I start my build over christmas break

I found the longfield website this morning and after looking at the real ones I think mine are standard birfs so I might upgrade to the longfields. The P.O. says that the inner shafts are the stronger chromo replacements but I haven’t figured out how to I.D. them yet. For all I know I’m getting smoke blown up my you know what.

The knuckle was pretty torn up inside with gouging on the top and bottom where the bearings meet the bowl. If the bearings were eaten up on the top and bottom of the knuckle does that tell me something I should be aware of like improper alignment which may affect seal and bearing longevity? Maybe I need the SST to make sure the shims are doing their job correctly?

I talked to a guy at work here today and he said I should buy an extra socket and turn it down a little to get it to fit between the caliper housing. I’m going to try that before doing anything more destructive like welding a bolt to it to get it out. Worst situation is a broken socket and wasted time.

Why should I be scratching the SSBC calipers? They are billet aluminum so they should dissipate heat better, they have bigger area pistons and the billet aluminum shouldn’t flex as much as cast steel so there should be less inconsistency when braking which should provide better stopping power. My stock axle which is currently on my truck needs a new rotor since my caliper came loose on my last trip to death valley and pitted the crap out of it. Either way I need to buy new brake components.

The rear axle has a disk brake conversion so I’m guessing that my LSPV won’t be needed since the P.O. parts truck didn’t use one with the 4 wheel disk brake setup. Not sure if my master cylinder size is correct to handle all four disks. Something else to consider as my SOA moves like a snail.

I will post pics of my status today in a few hours so people can help evaluate my status and point me in the right direction. Taking apart axles is fun and I’m glad I’m doing this.

If anyone wants to lend me the SST knuckle tool in a few weeks that would be awesome so I can make sure everything is assembled per spec.
 
Is there a proper way to get the spring clip off without smacking the inner axle / birfield assembly in a pipe? Anyone have a picture or schematic of what this assembly looks like without all the grease showing the spring clip and CV assembly?
 
If the issue with the brakes are that you have to modify it or modify tools to get it to work then why keep it? Not sure about you or anyone else but I run stock brakes front and rear with upgraded rotors and I have no problems locking up tires when I mash on them. Other bonus is not having to figure out what caliper I have to buy new pads, hardware etc.. especially in the middle of no where.

Don't get me wrong SSBC stuff is well built and definately brings the bling factor but we are just trying to offer suggestions to help in your time of frustration. I know that a SOA is overwhelming enough as it is and then throw in mods someone else did and I would go crazy.

Can't help you on the LSPV but I think I read somewhere that it will need to be modded because of the lift. The master will need to be replaced for the upgraded brakes. Look up Tundra master cyl and you have a bolt in upgrade.

Can't wait to see the pics!

I found out that the SSBC take OEM landcruiser pads so the only difference is the rotors which makes it a price issue as rotors need to be replaced every once in awhile.

If I keep the rear drum brakes I will modify the LSPV bracket and run it accordingly. If I go with the rear disk brakes I am curious who has done that and if they used an LSPV valve or difference master cylinder as stated. I have heard people using T100 master cylinders. You're the first to mention Tundras but that makes sense as well.

I will try and get pictures up by 5:30pm.

Aluminum flexes more than steel.
E(steels) = 29,700 psi
E(6061) = 10,000 psi
E(A356-T6) = 10,500 psi

It is possible to design around this deficiency of aluminum, but only a volumetric displacement test can tell for sure if the design succeeded. An educated eyeball might be able to make a guess, but I wouldn't bet for or against the results.

Until you know what the front calipers are going to be I'd hold off on thoughts of changing out the master. I'd first try what you've got and see how it well it works for you. Then if the master doesn't work like you want look into changing it.

sorry you are right it is the T100 master not the tundra :whoops:

What I have read of doing (in mini-truck circles), but have never actually done is to use a piece of tube or pipe that fits over the axle shaft and supports the inner race of the Birf. Slide the axle down into the tube/pipe and holding the tube/pipe in one hand and the stub of the Birf in the other whack the assembly against a piece of wood laying on the ground. Keep the web of your hand out of the intersection of the Birf and the tube/pipe. That hurts like a sumbeach!!!!
 
Wow those birfs are toast!

Looks like you might be able to run an allen bolt on there instead of the hex head?

Feels good to get it aapart doesn't it!

Keep it up you are getting closer!

Clint
 
you mean one birfield is toast. Not both right?!
 
Yes sorry just the one.

Have you picked up the brackets and such for the SOA portion?

I have some shock mounts that came with the "axle kits" just was going to bounce some stuff off of you on mounts.

Thanks

To remove the birf from the shaft:

Take a piece of 1.75" or similar tubing. Then insert the inner shaft into it and drop it on a piece of wood.

Does it wreck the spring loaded clip in there? I'm assuming that's the only way?

Dirtgypsy,
For shock mounts I plan on using the knuckle gussets from MC and ford towers in front. Not sure what I'm using for the back spring perch shock mounts yet. Probably stock plates turned upside down?
 
Now that I have the axles apart and completely disassembled I plan on doing the following:

Sending out diffs for regearing
Picking up a front axle rebuild kit from Mark’s offroad
Ordering Ruff Stuff perches and Anti-wrap bar kit
Ordering Marlin’s tie rod’s and 80 series pittman arm
Ordering Ford shock towers per Dirtgypsy’s P/N referral

Haven’t figured out what brake lines / connections to use yet
Haven’t looked into trany crossmember notching yet

What prep can I do to the axle housings while waiting for the regear and parts? Other than trim off old perches. I don’t want to paint it yet as I need to weld perches and do CnT.

My point is I want to move forward and I have next week empty other than ordering parts.
 
Not exciting but you can always clean stuff up so the paint sticks when you do spray it.

You could also separate your spring packs and repaint them. That would be good anyways to see if any of the leafs are broken.

You could grind off the old shock towers up front.

You could work on another smaller project you want to do to your cruiser while you wait.

You could get scab plates ready for your sliders
 
Good idea on the springs. That should keep me busy. :)
 
Its good to finally see it coming along slow poke ;)

You too. Better get sliders on your 60 soon or we can weld you up some because the eastern sierra trails done in the summer are not forgiving.
