There are other things but I can't think of them right now.

Here's some quick pictures.

Passenger side frame


Driver side frame


Welding Front Hanger on.


Working on frame plating.


Front Axle all Painted and ready to go. Thats my 3.4 swapped 95 in the back ground. Sweet truck.

Here's a little tech.

When doing the IFS Hub Swap on a Toyota front axle tap the calipers to 1/2" fine thread and drill the knuckles out to 1/2". Now you can mount the calipers to the other side of the knuckle.

Here's a picture of my new V6 IFS calipers 1/2" fine thread taped.


I'll get some more pictures of everything mounted later.

Here's my steering shaft.

This was completely bolt together, no welding needed. It might be long enough to work with an IFS steering box to.

i thought 95.5 and up was driver side diff drop?

yotaman

You would be correct. I'm converting the transfer to passenger side.

881stGenRunner

ha, i was jsut reading over your list of things to do to it, and noticed the MC07 adapter plate. whoops.

This is gonna be sweet!

Looks like an awesome build but, I am curious on something.
If its going to be a dd (commuter) than why not do an e-locker in the rear as well as the front, would seem to be more street friendly than the aussie?
Maybe you know something I don't so thats why I'm asking, not knocking your build at all, I think its cool!

Also,if you didn't already buy them, you might want to reconsider the Summit wheels, I have black 185 series on my '93 and a friend had polished 185's on his Chevy. They aren't real beefy, are made in China (if that matters to you), and my buddy cracked one of his wheelin' around an old quarry (actually was the first time I saw a broken wheel in person), just something to consider.

I have the 8.4 differential/axle and it's geared to 4.88. I'd much rather have the e-locker but already have what I have so I'll run it for now.

Thanks on the wheels, I haven't purchased any wheels yet.

the summit 164 series wheel looks a lot like the Cragar Soft 8 wheel. i havent had a probelm with my Cragar wheels yet.

theyre pretty inexpensive too. between $38-47/wheel

yotasavg

so what kind of a xfer case are you gonna run?

great project!

edit: scratch that.........dee-dee-deeeeeeeeeeee!!!

I love a vehicle that can drive to and from the trail and still get to work on Monday...Nice build. I need to get on top of mine soon.

crolison

sounds like what i would do if i was going to do a sas (spring under) either that or a 3link in the front

Some more pictures.

Axle under truck.


Truck sitting on it's own weight with tire on axle. The truck still has a 3" body lift that will be coming off.

Some more pictures of the IFS hub mod.

yotasavg

that looks really good! why did yo decide to do a SUA?

yotaman

To keep it low. It's hard to keep a SAS'd Tacoma or newer 4Runner low when doing a Spring Over. So a Spring Under keeps the truck low.

yotasavg

that's what i figured.....i can't wait to see it flex!!

also: what are you doing in the rear?

yotaman

It won't be a ramp champ but it'll flex fine. It'll do any trail I want it to do. I plan to take it on some of the toughest trails around.

Haven't decided on the rear yet. My plan is to get the front done then work on the rear. I'll probably keep it spring over and use the stock leafs. We'll see.

I got my tie rod and drag link ordered today. I had to have the drag link tapped 21mm on one side instead of 23mm so it took some time to find someone who could do 21mm.

BudBuilt is making both of them and they should be here next week. Then the truck will technically be drivable.

Here's a picture of my FJ60 tie rod ends. This is what allows me to use stock steering arms and do Spring Under.
