Just wondering..

[4RunnerChaos]

I'm not sure how the 01 and 02 3rd gens are but I know they have the center diff with atrac, I'm unsealed of how that system works. What I'm wondering about is how hard it would be to put the center differential setup into the older 4wd 3rds..
What components would one need to perform this??? Say... A center diff, and then front and rear driveshafts..?:noidea:

And if anyone has attempted or done so? Any links would be helpful just, living in northern illinois I like the appeal of running full time 4wd..

Edit: reading brian2sun's post on the different ssystems now. Seeing the 99-00 limited had the center diff and the rear locker was still optional.

My previous 4R was a 2WD 2002 Sport Ed. and it had the "Atrac" system. Correct me if I'm wrong, but I believe they changed it from a locking rear differential (optional in 96-00) to a limited slip "Atrac" differential in the 2001-2002 model years.

So I'm not sure what you're asking, do you want to put a limited slip in your 96-00 Runner? I would much prefer adding a locking diff over a limited slip for off-roading purposes. Besides, it might be tough trying to add a limited slip because I'm pretty sure the ECU is different as well.

The ATRAC system isn't a limited slip differential. It's just a fancy name for traction control. The differential is still completely open.
