locking differentials

[delloro]

I am wanting to get rid of my open differentials on my new 4runner.

I have posi on my xterra and I do love it, but no posi-type units appear available for 5th generation diffs.

I have never driven a Detroit-locker equipped vehicle, but I understand they take getting used to. An air locker seems preferable, at least for the rear.

Has anybody used a Detroit-type locker in front, and an air locker in back? The front-wheels driveability should not be a concern, as the front diff would only lock when under power in 4wd, if I understand correctly.

Thanks in advance.

You have limited slip in the front differential on your XTerra?

No, the rear. It's 2wd.

Does your new 4Runner have multimode?

You don't need lockers on either diff. The A-Trac will do everything you need. Especially for someone coming from a 2wd.

No, it's a basic SR5.

You could conceivably run an automatic or lunchbox locker in the front then. You wouldn't be able to use 4WD at anything but fairly slow speeds, and pretty much never on the street, but as long as you don't have multimode you could do that.

If you really wanted to lock up both diffs tight and could only afford one selectable, I'd put the automatic in the rear and the selectable in front. Anybody who tells you all about how scary automatic lockers are on the road is either a wuss or has never driven a truck with one. They're not that bad.

go with a selectable in the front, and a Detroit trutrac in the rear.
OR both selectable.

yup. selectable in FRONT if you can only do one.

ideally, you want them in both.

I've know three people to put in a mechanical locker in the front. They all swapped them for selectables shortly after. makes turning a ***** offroad when it's dry.


I'd run a mechanical all day in the rear. I just went with air lockers when i purchased. I didn't want to mess with LSD as it makes diff fluid changes or adding fluid a little more note worthy in the sense you have to add the right amount of friction modifier to the gear oil.

Whoever compared ATRAC to locking axles, may only wheel in mall parking lots? not sure what the thought process there is..


East Coast Gear Supply has been the go to source for toyota owners for complete third member and IFS clamshell's assembled with lockers as well as regearing. They have the 8.2 diff products as well. Not 100% sure about the front 8.2 locker availability but if anyone can make it happen it's those guys.

I definitely don't find myself using them as much as I thought I would. I wheeled for so long with open diff's I just got used to using momentum as an advantage. They mostly get turned on after I've gotten in hairy situations when opens just won't make it through no matter what.
