Topic: making a 2wd yoda into a 4wd

[toyota35bogger]

need a little info, how hard is it to do and i am doing sas so would it be just like the ifs truck?? thanks guys

[jimbo74]

it isnt that hard at all... and a 4x2 is a lot better to 4x4 and sas than doing an sas on an ifs 4x4.... as the 4x2s have a higher front frame arch....

it isnt exactly bolt in, but you will need front drivetrain... you will need driveshafts, tranny, tcase, tranny crossmember as its diff from the 4x2, front axle and all needed to mount the front axle

this thread might help out a little bit http://board.marlincrawler.com/index.php?topic=16374.0

and if you need mroe info, jsut ask... i have a 4x2, and since my tranny is broken right now, i am learnign pretty quickly about replacement options

[toyota35bogger [OP]]

so if the frame is arched a little higher in the front will that give me a bigger lift?? and thanks for the info

[jimbo74]

it wont give a bigger lift, however it wil allow using crossover steering with a lot less lift, meaning it will be possible to fit bigger tires without having a hugangous amount of lift.....

A lot of the 2wds came with manual brakes and manual steering. Which would suck in a trail truck. I would just find a cheap IFS truck and forget the 2wd to 4wd in my opinion. 4x4 Ifs toyotas in decent shape are not hard to come by in the less than 1000$ price range (at least in my area because the bodies are rotten). I think starting with a 4wd is gonna make life a lot easier for you in the long run. You are also gonna get a smaller rear axle being the truck is 2wd. That is only my opinion though.

[jimbo74]

a smaller rear axle meaning what? narrower? or do you mean the fact most 4x2s came with a 7.5" rear end... my 4x2 has an 8" rear end... its going to be a good amount of work, but from everything i have heard, its actually easier to convert a 4x2 into a 4x4 with sas than it is to sas 4x4 with ifs....

as my truck is an 85, the rear end i have is as narrow as an 85 SA so there would be no difference is track width of my current axle and a sa conversion

thanks for the info guys

I was referring to the ring gear. I don't see how it would be easier to do a full 4wd conversion than a sas. With a sas, you only have to mess with the suspension which takes a weekend if all the parts are prepared. Not do a tranny swap, fabricate a t-case crossmember, cut a hole in the floor, and do everything for the front suspension among other small things that will undoubtedly pop up. But I may be wrong.

Always broken if ya start with a ifs 4x you'll get a flat frame rail above the front axle.  That in itself means you'll have to run at least 4" more lift just to clear the hi-steer compared to a 2x converted.  Ill never build another truck froma  4x again if that tells ya anything.

[kneedownnate]

It might tell him more WT if you referred him to THE thread...

[WHITE_TRASH]

Oh yea good point Nate...  Here ya go for you viewing displeasure...  My junk buildup

[79coyotefrg]

yea cole,   there s ALOT more stuff that has to be cut off the 4x  4  than a 2wd,   the 7.5 isnt in all 2wd, some have the 8

[jimbo74]

my truck is a 4x2 and has an 8" rear..... it has a 2 pinion 3.07 gear ratio though, i nee to fix that along with adding a locker....

[alwayzbroken]

It would be nice not having to cut as much crap off. 2wds are even easier to fing than 4wds so that would be a bonus. Are the doors off of 3rd gens trucks the same for 2 and 4 wheel drive?

if they are the same gen, the cab itself is the same....

[alwayzbroken]

Really! That is good to know. So all the body parts will interchange except the fenders on a 3rd gen?

[jimbo74]

wait, are you talking about a truck thats 4x4 and 4x2 or a truck and runner? runners are different than the trucks, espcially because the equal gen are different entirely.... a gen 1 runner is 84-88 an 84-88 truck is a gen 2 truck

hey jimabena74,
i have a couple of truck i am in the build of a 4runner right now i just wanted to now how hard it was to make a 4x2 into a 4x4 thanks

[79coyotefrg]

not that hard

[WHITE_TRASH]

As to what body panels will interchange thats easy.  If it looks the same as what you have it'll swap over directly.  Fenders doors hoods etc all fit within each generation.
