I just completed a rebuild of my driver's side steering knuckle, wheel hub, spindle and brake components - adapting the Longfield studless hubs, chromoly spindle and the 48mm 4-piston caliper with 338mm rotor from a 2015 4Runner. With careful planning and some minor machining work, everything bolted up very nicely! Only the driver's side has been completed, as a proof-of-concept allowing me to evaluate the installation and note any changes to be incorporated into "round 2" on the passenger side.Overview:
The FZJ105 is essentially the same chassis as the FZJ80 with wider body mounts for the 100 series body.
Over the years details have trickled out on Mud about various changes made to the FZJ105 compared to the FZJ80. This thread is intended to be a FAQ link or Stick that lists as many as possible, the next 7 posts will be summaries of the respective systems. I will edit/update them as information comes in.
FZJ105 and other newer Toyota parts that are upgrades and can bolted on the FZJ80 will be noted (I.e. steering sector shaft).
I also want to note aftermarket upgrades that are directly analogous to upgraded FZJ105 parts that don’t fit on the FZJ80. (I.e. the FZJ105 has M10 hub studs where the FZJ80 has M8 studs. The M10 cone washers hang out past the FZJ80 hub, so those won’t work but Front Range Off Road sells stronger M8 ARP studs, so they get an honorable mention).
Aftermarket parts that allow for the use of newer upgraded Toyota parts will be note too. (I.e. upgraded knuckles that allow for the use of larger current model 4Runner brakes on an FZJ80 or and adapter kit to bolt a A750F 5 speed to 1FZ would get mentioned.)
Enjoy!
I'm trying to consolidate all of the information that I have, to do a write-up of the project. I'm a bit of a noob when it comes to posting write-ups, so this should be a fun intro!

Wait...what??? This deserves it's own thread. Details sir....
What?
What am I looking at???
I'll definitely start a new thread for the write-up, and yes, details will be plentiful!Wait...what??? This deserves it's own thread. Details sir....
I stumbled upon this post yesterday and really liked the thinking unfolding here! Given the massive amount knowledge and experience present on this forum, this could get really interesting - quick!
It's a hybrid unicorn...
Rebuilt 1997 Toyota steering knuckle.
Trail Gear spindle and studless hub.
2015 Toyota 4runner brakes.
Yeah, this really a inteesting subject... will this be same track width or is there a wider option like 3" wider IFS hubs on none IFS axle on Yotas?
Bayou, plz do a how to on the 4runner brakes. I want to do this to the FZj80, 2015 4runner Big brake kit.

I can’t recall the post, but I inquired a month or two, about big brake kits.
There was a member who did a kit, split & cut OEM rotors, made a hat, & went with big rotors & calipers.
Witts End had posted in the discussion about making the kit.
I recently poked him about doing it to compliment his turbo kit that is coming along nicely.
I can’t find it on my phone based internet though....

In your first post of this thread you have the stud sizes wrong. You might consider editing that post to avoid confusion. The two sizes are M12 and M14.
100 Series switched over to a 5-Bolt pattern using 14mm studs.
80 Series kept the 6-Bolt pattern with 12mm studs.

Of course that guy that makes this awesome discovery makes 4 posts then disappears. I've been curious about these studless hubs for years and could never figure out if they worked on the FJ80 or not. Anybody else have other insight as to what kind of machine work is required? This along with Nick's recent 5th gen 4Runner brake upgrade has me really interested.
I feel so behind the times: TG Studless Hub on FJ80

Anyone on mud tried this? Asking for a friend...

in for more info. looking for caliper bolt length and whether wheel studs need to be swapped out with longer studs!
