there is such things as 4X4 prerunners rfcruse but if you really really don't want 4wd all you would have to do is what was said earlier, remove front diff, cv axles and the front drive shaft, as for the trans/transfer just get yourself a 2wd trans and maybe the driveshaft (not really sure if it's the same between 4wd and 2wd I am sure with a little searching I'd find the answer to that.)

I have said this before on here somewhere, FYI most 2wd prerunners are converted 4X4 vehicles.

But what I would do is go with a Long Travel front, keep the 4X4 and widen the rear and have the best of both worlds.

Thanks to those of you who actually had some useful information for me. For those of you who provided unsolicited opinions... I'm sorry your mother's days are so empty that you have found it worth your time to blather on about how cool you are and how stupid you think i am.

It's unfortunate that this Forum has far more opinion than knowledge.

More and more misguided information is being posted on YT lately. If you don't know what you're talking about, please don't post it or make it clear you're not sure.

You can run any non-offset axle you want. This has NOTHING to do with the transmission. So NO you don't need a 2wd 7.5" toy axle to go to "2wd."

You don't need to swap in a 2wd transmission UNLESS you wanted to save the little bit of weight by eliminating a transfercase. This would require new crossmember, new transmission and new rear driveline (lengthened)

Removing the front diferential and CV's would leave the wheel bearings open to water contamination if you subermeged the spindle since the spindle would be open to the elements where the CV shaft actually inserts in.

Unless you're hardcore into pre-running removing all the 4wd components will not give you any significat increast in gas mileage. Just compare a stock pickup to a 4runner with the same motor. Gas mileage isn't more than a mile if that.

Better off leaving it alone or buying a factory 2wd runner.

4runners werent made available in 2wd versions till 1989, fyi. Which was when they introduced the new body style with a non-removable top.

Woops, If it was I that went too far I appologize. I didn't mean to be mean.



Some times I get carried away. My bad

Perhaps you should reread this and follow your own suggestions

This is not true on pre-Taco "early" IFS. The CV isn't exactly sealed to the spindle, and the bearings are on the OUTSIDE of the spindle, so the chance of water contaminating the bearings is no worse than with the CV installed. But if it really freaks you out, just pound a runner stopper into the spindle.

There are 2WD versions of all 4Runners, at least through 3rd gen.

If you want a 2x4 then buy a 2x4. In my opinion thats the easiest way. I would think that removing the 4x4 would devalue your rig unless you went with a super cool long travel kit : ). If you want more gas mileage then you should probably get a car .

First off, show me a 2wd 4runner pre 1989 in the USA. Second off, the spindle being open from where the CV inserts in, goes straight into the hub. There is no seal or anything to stop water from filling the hub assembly if you submerge it. Water will enter the spindle, into the hub and then gain access to the entire hub where the bearings reside. Theres a rubber seal on the the entry to the spindle where the CV slips in that rides on the CV shaft.

You got one thing right, IFS hubs by design aren't leak proof but water resistant at best.

if removing the cv from the 4wd spindle is so bad then why the heck does Total Chaos use modified 4WD lift spindles in the 2wd caddy kit?

I only mentioned the 2wd trans and driveshaft IF he wanted to remove the x-fer case.

pre 86 4runners did not come in 2wd at all US or otherwise. They were all SFA.

only mention I can find about 2wd 4runners were 90-95 in both 2.4 and 3.0 flavors and the 09-present base SR5 and Limited's come available with both 2wd and 4wd

who the hell came up with the long travel bull crap?!?!?!? the guy never said ANYTHING about long travel...NONE WHAT SO EVER.

the guy asked a simple question...and all you guys can do is flame him...wouldn't surprise me if he left yotatech.

you people remind me of pirate4x4 LOL

and i have NEVER seen OR heard of a 2wd 84-89 4runner.....ever

now 90-05 has 2wd's...because there is a stock one in my town.

the suspension setup is IDENTICAL to my '86 IFS and my '92 IFS

Yup... not looking for long travel setup, just a simple, bulletproof, fuel efficient runabout that I can haul either 4 people or my camping stuff in/ sleep in....and be able to take the top off. MPG difference on 1993 4runner 4wd V6 auto vs. 2wd V6 auto is 3 MPG City / 4 MPG highway. (www.fueleconomy.gov) That a substaintial difference IMO.

the only reason why I brought up long travel was to point out Total chaos is using the 4wd spindle and no front drive shaft in there caddy kit for the 2wd's. I never flamed him BTW.
