Hey boyz i wanna convert my 98 4runner to 4wd and i was wondering if a 96 tacoma tranney and transfercase would fit on my 98 2wd, and tips would be greatly appreciated thanks from Hawaii.

 

Unless you're planning a SAS, you'd be better off just selling your rig and buying a 4WD. Or if you've got plenty of spare time and access to parts then go for it. You can make anything fit if you really want it to. But yeah, a 2WD would be fairly easy to SAS.

 

Well the 2wd 4Runners basically have the same brackets and all as the 4WD's.

There has been plenty of Prerunner to 4wd conversions on Tacomas and it would basically be the same thing for you.

If were going auto to auto or manual to manual I think you should be ok there, I know both 2wd and 4wd 4bangers use W59 (5Speeds)
Same for V6's they both use the R151 (5Speeds)
Autos 4bangers are A340F and V6 are A340H (I believe, Deff search for that)

Check out TTORA and find a few of the prerunner to 4wd builds and youll be good to go on that.

 

try asking iceman601 about it. he converted is 2WD 4Runner to a 4WD..

also look for his post about it here in yotatech & maybe in ultimateyota also.. lots of pics and info about the conversion..

 

Rude, I have thought about making my 2wd a prerunner, with a rear locker, it would be an easy swap as the whole rear axle can be found at a salvage yard, and would bolt right on

 

Sell it and buy a 4wd. It's just not worth the effort, not to mention it's effect on resale value.

 

From what I have seen it seems to be quite a bit of effort to convert from 2wd to 4wd ifs. Guys have done it. To each its own, but from my point of view its not worth it for ifs. You are probably better of doing an sa instead of ifs. It looks a tad bit easier too.

 

This guy here did exactly what you are looking to do:

I don't know if I can be much help, as mines a V6 and auto.

 

I'm about 95% done with doing a swap from a 1997 v6 2wd auto limited to 4wd auto 3rd gen.

Most of the key elements and pictures can be found on www.sonoransteel.com, but when they did their conversion, it was a 5-speed, not an auto. In addition to that, they chose to use manual locking hubs from a tacoma, I used a set of sequoia/4runner hubs/spindles.

Parts needed:

Non-ADD front differential from a Tacoma (I believe 1995-2000 will work)

CV axles from any 3rd gen 4runner

Spindles/Hubs from 3rd gen 4runner or 1st gen Sequoia

Optional, front differential drop spacers (I bought mine from sonoran steel)

Front drive shaft (Toyota calls it a propeller shaft)

4wd transmission and transfer case from the same engine as the one in your truck, find a transmission and shifter assembly WITHOUT the 4wd selector button, the one with the button is the ADD model and that would require that you purchase and install a lot more items. The transfer case shifter is different towards the bottom, the non-add model has an all metal bottom, the add model has a round plastic piece, I went with the non-add model, since I was using a non-add front differential

Rear driveshaft, when you purchase the transmission/transfercase or rear driveshaft, make sure it comes with the bolts that connect the driveshaft to the rear pinion flange, the nuts are special order and are extremely hard to find other than the dealer, the nuts are M11 x 1.0. I also chose to buy the rear driveshaft from a 5-speed v6 3rd gen 4runner/tacoma because it was about 1.5 inches longer, I have a 2.5 suspension lift and 1 inch body lift.

Rear engine mount (transmission mount) will need to be fabricated. The guys at sonoran steel made their own mount. I chose to use the factory rubber mount and have my local welder extend the #3 crossmember to connect the mount and crossmember. I will post pictures later of what I'm talking about.

All the items listed above are installed and working fine which equates to about 95%, the only items left are to re-gear my 3rd member to 4.30.

One last thing is the transmission filler tube (Transmission dipstick tube), on the transmission that I bought, the filler tube connected to the transmission is shorter and at a totally different angle compared to the 2wd transmission.

I think that is pretty much every. I will post pictures later. I hope you find this information useful. It took me quite some time to find all these parts from other members and local salvage yard. I will also post part numbers what I had to buy along the way.

Good luck...

 

Sounds like you've gotten some good info but if you haven't already, try searching.
This topic has been discovered in detail - I can remember several years ago reading at least a 5 page thread about it.

Good luck.
