I looking for a new or near new ARB locker for the rear of my 2000 4runner.

 

You need part number RD132 or RD23. There are hundreds of online stores that sell these (ebay for example http://cgi.ebay.com/ebaymotors/ARB-A...pagenameZWD1V), and most offroad shops sell airlockers too

 

Looks like I need a RD132.

 

im plannin on gettin one of those sometime, will do the back and not the front, since i plan on doing a sas swap sometime in the next year, and i figure why waste the money on the ifs? my question is, how hard are these things to install?

 

I may pull and remount my 3rd member but I will be paying someone to "setup" the diff. All I know is that the backlash must be right or it will gernade.

 

Thats what i did this past weekend. Pulled out the third took it to a reputable shop and then installed it back in the next day. Only cost me 60 bucks to get it set up. Same shop would have charged me 250ish to pull it and do it. Its not hard to pull it yourself and put it in.

 

yup, thats what i did. bought spare diffs, gears+install kits. got it setup and an rd90 installed and swapped em in myself. unless you've got another ride...then you wont need to buy spare diffs. you can just pull re n re it.
