79 fj40 disc brake conversion front and rear

[calponte]

I'm going to order all the parts for my 79 in a week.

I've read guppies write up and it was awesome, although I still have questions.

He seems to be doing what I want to do and just rebuild to a mild slightly better than stock build.

What I didn't see was an exact place to get everything and if there was a more preferred part over another today?


I want to install power steering as well and would like to know what is needed?

Is there a company that has all the right stuff for one stop shopping? lol

Thanks for the help

I finally ran out of inventory on all of the Downey NOS steering conversion parts, but I do still make (and will continue to make) the power steering custom hose kits. I am down to my last 8 Downey NOS rear disc brake conversion brackets and hose kits, when they are gone, their gone. Problem with sourcing from me is you would not have a "one stop shop". I do, however still have the Downey power steering and rear disc brake conversion instruction sheets. Lemme know if there is any way I can help.

As far as I understand it, it's all stock fj 60 components right? That's what you have? Couldn't I just go to my parts store and buy the stuff?

If I bought used takeoff assemblies from a 60 what would be a fair price?

PM me your e-mail address, I have a spreadsheet including part numbers and sources for front and rear axles (at least the way I did them). I ended up spending about $1100 on the front and $1100 on the rear, but this included completely new brake lines and lots of parts I probably could have gotten away with reusing, as well as new brake lines, extended breathers, and a refresh of my dif's (but not a complete rebuild).

If you have a 79 FJ40 you MIGHT already have most of the components, as this was the chaneover year. I'd suggest checking before you buy, as late FJ40 front outer axles and FJ60 outer axles are pretty much the same (large pattern knuckles, front discs, large pattern, fine spline birfields). If you don't have front discs in your 79, it's not a US model truck (I don't know where you're posting from).

If you do have drums and coarse splines, then you'll need a late FJ40, FJ60, or early mini truck (I think pre-1984) front axle assembly. The inner axles are the same. I bought all the outer axle components from an 89 FJ62 when I did mine. I think I spent $200-$300 for knuckles, spindles, birfields, steering arms, hubs, and wipers. I've seen better deals on front axles but I took what I could get when I needed them and they were in great shape. $200-$250 seems to be a pretty average price most places. I then went out and bought new calipers and rotors from NAPA. I also replaced the wheel studs and knuckle studs "just because." I bought knuckle rebuild kit from Kurt at cruiser outiftters including the Marlin inner axle seals and Koyo* wheel bearings. I believe this ran me just under $200.

*Looking at the spreadsheet I just sent you I actually went with Timkens.

For the rear's, I bought the rear axle disc conversion kit from Poser here on MUD, including brackets to mount Monte Carlo calipers, and custom bored rotors to match. I bought the Monte Carlo calipers themselves from NAPA.

I also have completely rebuilt my Saginaw power steering setup. I have a lot of part numbers and prices for that setup as well. However, there are other power steering options out there, so it all depends on what you want to do. Lots of pictures in my thread (linked in my signature). It's sort of long/scatterbrained but lots of good info in there. I'm trying to keep a Table of Contents up in Post #1.
