Converting from 2wd to 4wd

Has anyone out there converted their 2wd 4runner or tacoma to 4wd? If so, what is involved in doing the conversion? Is it as simple as hooking up a transfer case and doing a SAS on the front? Any info would be great. Thanks

PS: I tried the search function on all the forums and came up with nothing. If you have a link to a thread, please just paste it on here for me.

to just convert to 4wd ifs?

thats not 5-8k, not even close.

all you need is tranny and tcase out of something with the same engine, front diff with the right gear ratio, cv's, manual hub spindles, manual hubs.

thats all you need to do it.

The FAQ's posted are a great source.
You are gonna need an axle with a driver side pumpkin..Are you talking about going IFS, SAS with traditional leafs or coils??

a couple of threads:
iceman's https://www.yotatech.com/forums/f2/2...mplete-141506/
sar squid's http://www.ttora.com/forum/showthread.php?t=68120

probably one of the more expensive 2WD to 4Wd conversions but I would love to have Revivalist's Truck:

He was saying SAS, and that just seems like it would be a BI#&H to do, and fairly costly
Yah Ifs would be much cheaper, like 2k?

thats the mechanical part of it but you would also nned the new interior trim piece in front of the e-brake with the cut-out for the 4x4 shifter, a new instrument cluster with the 4wd indicator in the center, a new ecu? probably other various odds and ends, a new rear driveshaft as well

Seems to me that it would just be easier to find a 4WD rig.

Its usually just better to buy a 4wd, the swap is not usually cost effective, especially for the older trucks.

He would need the new trim piece and to cut out the floor shifter area.

He doesn't need new instrument cluster, no new ecu... Your running manual hubs, there is no computer for manual hub'd trucks, its all mechanical. You can wire the transfer case switch and route it to a bulb in the 4wd light socket in the instrument cluster. But it would be simpler to just look down, oh i am in 4wd. If you wanted to use ADD you still wouldn't have to deal with that crap, you could just wire up the solenoids to where you controlled there locking and unlocking.

I forgot about d-shafts
