Automatic rear locker?

[Tradera]

I'd like some feed back on an automatic rear locker on a 4th gen. I know this type of locker can be jerky on pavement I've had them on older runners with manual transmissions. I just haven't seen munch info on lockers in 4th gens besides the ARB. I like the simplicity of the auto lockers my self , but never had the chance to drive an automatic transmission with a locker like the Detroit or other brand auto lockers.

Any thoughts would be appreciated.

Thanks.

Although Toyota refers to it as an automatic locking differential it is an open diff. The only traction aiding device is the A-TRAC 2+ which will use the brakes to slow down a spinning wheel in order to put power to the wheel with traction.

The A-TRAC system is pretty effective, especially with center diff locked when you are in low traction situations. I was recently up in the mountains and the road had deep rutts and was very muddy. With marginal tires I was easily able to climb out of the rutts when I met another vehicle or the rutts started getting to deep - without the A-TRAC the rear tires would have pushed me and one front tire would have spun. I would have had to back up or used more speed and risk of bad results with past vehicle. I just got the 4r earlier this year so still learning what it can do. Looking forward to chaining up all 4 and trying deep snow this winter.

Old thread I know but neither response to the original question was relevant at all to the actual question. Auto locking device was intended to inquire not about all the electronic gizmos to assist with traction but an actual physical automatic differential locker. This would include such devices as the LockRite, Aussie Locker, or Detroit Locker. The inquiry was about the effect one of these devices has on roadway drive-ability and what negative side affects may arise with this type of device in a differential being powered by an automatic transmission.

I had the same question and when I found a thread with a search relevant I was genuinely pissed off at its lack of relevance and "deadendedness"

So again to re-emphasize the point, DOES ANYONE HAVE A SET UP LIKE THIS, AND IF SO WHAT ARE YOUR THOUGHTS?

Hahaha, that made me chuckle a little.

I would like to introduce you to Toyota120 you'll find more info over there.

Have you looked at the Truetrac? Not a true locker, but it's supposed to be very effective working with ATRAC, and smooth on the street. You could also check out the Grizzly locker as well. Very similar to the Detroit, but supposed to be smoother. T120 is a great place to get more info on the topic, but your just going to get told to buy an ARB by most

Not everyone is a fan of ARB's which are very expensive and not exactly trouble-free as auto lockers are. Anyone who has dealt with a bad O ring or mystery air leak will vouch for that. I plan on a Truetrac when I decide I need more than I have.

Some people insist that auto lockers are dangerous and hard to drive on snow and ice which should be interpreted as "I don't know how to drive on snow and ice" rather than blaming the locker.

Search again, then, because we just did this exact thread just a couple days ago, and it has exactly the answer you're looking for.

I had a 2001 Tacoma Auto, I slapped in a auto mechanical locker, DETROIT, It worked really well. I had no complaints. However rapid acceleration around a corner will lock the rear tires together, not fun in the rain for someone who is not prepared for what can happen... Ask my GF how she knows.

All in all I would not hesitate to do it again. Just have to re learn to take corners in the vehicle.

Wonder if this would be better or worse in the 4R with full time 4WD. I'm thinking the front might help pull around the corners instead of just the rear pushing too much.
