That popping and banging is enough that I'd always be worried something is wrong with it. I've seen lots of good things about the truetrac, just never wanted to spend that money on it.

 

Auto lockers both lunchbox and full case don't lock under power, they are always locked unless you are in a turn where the outside tire has enough traction to spin faster than the carrier then it will uncouple and overrun the carrier, that is what the clicking noise is that you can sometimes hear. In a turn since the outside tire is uncoupled only the inside tire is being driven, if you give it enough gas you can chirp the inside tire because of this, but that's usually not an issue, the locker re locks when the inside tire catches up with the outside tire.

 

Have a read here.

 

His explanation is incorrect, you can read how they actually work on the manufacturers websites.

 

Well that's certainly odd, considering that every other article I see about them, from various off-road type places, all say the same thing. Do you have a link that says otherwise?

Most resellers do NOT recommend them for daily drivers..... Here is only one example.

Edit: Ok, the powertrax lock-right locker works slightly differently, it basically 'ratchets' when the outside wheel needs to turn faster.... Really not a bad design. As for the rest.... well, most appear to use engine power to keep them locked....

 

Not sure why they say that, like I said I have daily driven with them for years, I'll get you some links explaining how they work when I get a chance.

 

Probably due to the way that one works. It does indeed use engine power to lock the diff, so, if you are cornering, and accelerating at the same time, it could get exciting on low-traction surfaces. If I had to guess, I would expect the lock-right wouldn't have that problem.

 

They all work the same way.

 

Uh, no, they don't. Thought I had already shown that...... The first article I linked talked about the oval hole, and adding power causes it to lock. The powertrax unit is ratcheting, so, it really doesn't matter how much power you are pushing thru it, if the outside wheel in a turn needs to spin faster, it can. (unless of course you are also spinning the inside wheel..... but, that's a whole 'nother kettle o' fish.)

 

They are both like that both have oval holes and ratchet when you turn, also have you had problems driving on the street with any of them that you have owned?
