Disc brake swap on 73 fj40 (1 Viewer)

[Rumrunner439]

I just picked up a 73 fj40 the other day and I want to do the front disc brake swap. I thought about swapping in a fj60 front axle so what is the best year axle for that swap and what all needs to be done for the swap( I am new to the forum, and not new to wrenching or fabbing). This is a power steering and it has a brake booster already, I just rather keep it Toyota brakes over the gm brakes. This truck has the chevy 350 conversion done already but will probably be pulling the old 350 out and either a 6bt cummins swap or the ls 5.3 since I have a few of those engines sitting in my shop. They also swapped a gm 3 speed manual trans in it and did a lift already. The body is in ok condition but no top or soft top and no doors. So I will be looking for some soft top doors and eventually a whole hard top set up. I edited this to add some pics and yes Im cheesing next to my new toy! I have wanted a fj40 for a long time.

When and if you need them, I have the 5.3 front motor mounts in my ebay store at a decent price for Mud guys, lemme know.

Plenty of threads on this swap, but basically the 60 axle swap requires out - boarding the springs to clear the third member. It's simpler to throw the 60 knuckles on your 40 housing. If you do want to go whole hog, I would (and do) use the FJ62 axle housing. They come trussed from the factory.

Welcome to the bad habit! 60 knuckles and arms have a larger TRE taper, so if you are keeping stock 40 steering, you must get TRE shims. Cruiser outfitters has those. I would also get fine spline 40 series axle shaft kit from RCV. Grinding your inner housing knuckle balls will have to be done, as well as a full axle knuckle rebuild with marlin inner axle seals!

Mini truck front disc setup also can be used on your front axle housing

Post up some pics let’s see what you are working on is it a sm420 or a sm465 tranny. I’m still running the old 350 with the Rochester quadrajet carb in my rig. Ive seen a cruiser with the 6bt in very nice.

Swapping in an entire 60/62 series axle is gonna be messy.

Using the 60 knuckles on the axle you already have is a decent way to go.

I agree; post up some pics.

I think I have the same set up as you with the sm465 3spd but I was told its actually a corvette 327 engine. Ill have to find the numbers on the engine to be sure.
