I wasn't able to afford a 4WD at the time so now I have the oppotunity to buy a wrecked '94 4WD dirt cheap. I've checked the specs. It'll work, but what do you guys think?

 

Everyone is going to say it will be a lot easier to sell the 2wd and buy a 4wd. The reality is that you should do what makes you happy. If you are attached to your rig, convert it to 4wd. If not, sell and buy a 4wd.

 

There is another thread https://www.yotatech.com/forums/f31/...roader-135455/ just started also.

neliconcept had a 2wd 4runner. He liked the vehicle so he converted it to IFS 4wd. If I were to do it I think I would go SAS since everything is new. It can be done. I don't know what he spent.

There is a shop that does SAS on 3rd gen 4runners. Kits too.
