Double Axle Swap Front SAS 100 Series LX470 to LX480 or LX105 UZJ100

[SoCal FZJ80]

Like Duggy said, trying to retain 5 lug for anything is counter productive. This is based on cost and future flexibility. The 100 series wider rear axle only exists to match the track width of the IFS setup. And the offset of the front wheels only exists to allow the UCA/LCA spindle setup to be longer and still keep the tires tucked under the fenders.

I will go further to say, It is in your best interest Financially to source a 93up FZJ80 that is body damaged, has a bad powertrain, ruined interior, or even better yet... All three defects. You need many parts to do this conversion right. It is less expensive to buy a damaged
or salvaged vehicle and harvest all of the parts from it, rather than buying parts individually ala cart. Not to mention the savings in time not searching and waiting for components to arrive in the mail. Later when your build is complete, sell off or donate the remainders to the rest of the Ih8mud community. Please don't kill a perfectly good 80 series if you can help it. The 80 is a future collector item, keep them in the circulation of enthusiasts.

In this build we harvested 90% of components from a donor 80 that had a dead engine plus many other defects.

Short answer is no. The 100 series IFS hub has larger bearings and a different spindle. You could go with 105 hubs and 80 spindle and retain 5 lug, but at the tune of $450/hub and little availability, it's a hard pill to swallow especially if you need a replacement hub. 6 lug also gives you the ability to fine tune your offset since there is a much larger selection of wheels as the 80 track width is narrower than the 100.

Here is a picture of the coil bases welded in. Relay steering arm made at custom length. Power steering high pressure hose is made from taking both the original UZJ100 and FZJ80 high pressure lines and having a hose shop make one that has the pump side for the UZJ100, and the gearbox side of the FZJ80. Power steering gearbox from the FZJ80 will need to be installed on the UZJ100 frame. We drilled and sleeved the four holes just like the OEM FZJ80 frame has them. I will look for pics of that process and add them to the post. You will also need to combine the lower column to gearbox steering shaft of the 80 series with the lower column to rack & pinion shaft from the UZJ100 to adapt. Again having all of these parts on hand reinforces the value in having a complete donor 80 series standing by for parts acquisition. You can reuse the original front sway bar by reversing it and running upside down putting the curve that normally goes around the driveshaft over the pumpkin on the axle housing. You will need to make bushing standoffs on the axle and two drop down mounting tabs (similar to shock tabs) on the frame side.

That sway bar setup is sweet! I don't have one in the front, but am thinking about doing an anti-rock setup to allow for max flex but also regain some sway on the road. At this point, it's not that bad since the ORIs do really well at this already. What did you guys do for a steering stabilizer?

@SoCal FZJ80In other words, is it possible to do an SAS swap on 100 without having to swap the rear axle and retaining the larger brakes of the 100?

Yes, you can convert the rear axle to 6-lug and benefit from the added width especially if you are going 37" or taller. Then use a custom or widened front axle to match.

If you do this, you may as well leave the rear axle alone and keep the front 5 lug.

With Front Range Offroading introducing new 80 series hubs that will accept larger brake calipers the point of retaining 5 lug is difficult to justify.

What happened to this thread!!!!!!?????

What happened to this thread!!!!!!?????

Uh I think people stopped posting in it. @LX470Beast I think bought the rig and never wheels it but reminds everyone of his 10" lift constantly

This is Actually the build thread for my LX. Some improvements were made to the original build but I still daily drives it and seldom wheel it because I really don’t have time. It’s been trouble free.

 

[LX470Beast]

Just to clarify nukegoat, I had it built because I can. I’m not a cheap cake and love what XTREME Lancruiser have done. I didn’t half a$$ just in case I do decide to wheel it someday. With that said it’s the only LX470 with 10 inch lift sitting on 38” that does not look like roller skates. FYI when I did wheel I launched it on the air and it held up pretty well. Now I’m toying with 2017 LX570 because once again because I can. So please don’t hate.

What is a 10" lift anyway

 

[Alibaster]

I’ve been told. 2.5” lift feels the same but maybe they’re just being nice I dunno

It’s 2” short of a foot, duh

 

[LX470Beast]

Compensating options...

 

[OEMGUY0720]

Curious what front and rear coil springs you used. Overall build is five stars imo.

 

[LX470Beast]

Not sure what the brand name, but I know that Ryan got them from Australia. It’s a 80 series coil and springs.

 

[vman07]

Can we some some current pics?? Please?

 

[OEMGUY0720]

Not sure what the brand name, but I know that Ryan got them from Australia. It’s a 80 series coil and springs.

Interesting. Is it still 80 series specific or it’s something you got for a different make and model and then retrofitted to work for the 80 axle components?

 

[LX470Beast]

No I believe it’s 80 specific.

 

[OEMGUY0720]

No I believe it’s 80 specific.

Sweet. Thanks man.

Here are some updates since build. Hydraulic assist steering. Initially the truck was hard to control at high speeds, I had a lots of play on the steering.
