Default What do I need to know about wheeling an IFS Toyota

Just as the title states...

I'm finally getting near the point where I can spend some money on my 86 4 runner.

Gonna stay small for a while. Bumpers, sliders, rear locker, 31" all terrains I got for free.

I think my main questions relate to steering. Is this a weak link in IFS toyotas? Do I need to strip all the steering components at the junkyard so I have spares? What do I need to worry about?

Carry a spare CV and idler arm. The idler is a weak link; consider upgrading it.

You're gonna hate those 31s...

Pick the high level line where possible, and be aware that instead of that front tire dropping into the hole, the whole front end will tip into the hole. IFS will teach you skilz though.

That vintage of IFS is robust - except for the idler.

x2 on the idler.

A decent brace can be had from Downey offroad for fairly cheap.

Total Chaos makes a 300 dollar replacement that will fix it for good.

CVs are all about the gas pedal.

Don't hammer the gas, and it'll be fine, and don't try to climb a rock or ledge with the wheels turned fully over.

Front lockers help with CV breakage, but not sure how much coin you are looking to spend.

Junk yard or SAS spares are good to have. I'd consider getting an idler, and a set of tie rods.

Idler arm - Check
This Looks like the Downey Product. For $50 I think its the ticker.


As for tires...

I know I will probably hate the 31's. I got them for free and they are almost brand new. I may step up to 33's, but then re-gearing is going to be mandatory.

Am I correct in my understanding that a front locker will help not break CV's? That seems counterintuitive to me. I'm not opposed to a front locker.

It will help BREAK the CVs... if used foolishly.

That is what I would have figured, I'm guessing AxleIke meant that lockers help break CV's

Wheeling in an IFS truck can't be done. Don't try such insanity.





If you insist, here's a couple of trucks (besides AxleIke and tc) that I unashamedly steal ideas from.

http://www.yotatech.com/f86/sonoran-...y-28-s-104077/

http://www.4x4wire.com/toyota/hottoy/west/

I have a Total Chaos idler arm. Previous to getting it I only ruined one idler and that was when my truck was very stock with 30" tires. They are the Achilles' Heal of IFS. Surf over at Yotatech and find the thread about using brass bushing in the stock idler, that helps. Or use the truss like you show. Ideally you do both, the truss keeps the arm from bending and replacing the nylon bushings increase the life and reduce the tendency for the shaft to defect into the frame horn.

I think the idea with a front locker is that it divides the torque between both wheels and that can help reduce breakage. Plus it helps you crawl more than do the High Flying Hilux Dave act. But really, with a locker I would think you'd be more prone to breaking axles overall.

BTW, found a picture of my stock idler compared to the Total Chaos. There really is no comparison.

Cool. Thanks for the links, those help.

I'm undecided on a front locker. I'll probably due without until I start taking it places where I wish I had a front locker.

Plans right now:

Tires
Rear aussie Locker
Front / Rear Bumpers
Sliders
Budbuild cross memeber
Idler brace
4.7 t/case gears

Items I am considering
winch
Front Locker
63" chevy rear springs
Ball Joint Spacers
U Bolt Flip
1" body lift with drivetrain lift
Bigger tires / lower gears

I see your point, but at this point I can't justify spend the money on it. Ask me after I bend a couple
