Occasional banging is normal, so is a little tire scrubbing, never heard of anyone shreding the teeth off of a Lock-right, they will however slowly wear down over time.. I doubt you'll break the cross-pin, you're more likely to take out joints and shafts, and if it's still a D30, the gears themselves. I blew up the crosspin in my 7.5 with a lock-right, but it was never put behind a 4.0 from the factory, let alone on 33" tires, and I've got a heavy foot.

I've daily driven rigs for almost 4 years with locked rear axles, including the lock-right, and wouldn't trade it for anything. I don't recommend the No-Slip, I hate it's manners compared to the Lock-Right and Aussie Locker but at the end of the day, when I put my foot down, it locks and I get moving.

 

I had a Lockright in the back of my old Cherokee, and front and rear in the TJ for a while (6 months). I took the rear one out as soon as I could and installed a Detroit SoftLocker. The worse was the bucking when coasting into a parking spot. The whole Jeep would buck back and forth as the front and rear fought against each other. It was the craziest thing, and was very harsh.

I've had two different friends try and save some money and put a Lockright in the back in their D44, and both of them broke within a couple months. On the other hand, I have a friend who has one in a D35 who has wheeled for 5 or so years on it. Some have good luck with them in the rear, I haven't.

After switchng to the Detroit I'll never put a lunchbox locker in the rear again.

 

ya isnt it lsd it only ingauges when on the accelerator, can stil burn both tires off

 

No, an automatic locker does that. A locker will not spin faster than the ring gear. It allows one side to run slower around a corner when not on the gas. An LSD lets a tire spin faster or slower than the ring gear.

For an LSD, however, the Tru-Trac is the best.

 

There is nothing inside of it to engage or disengage, that's what lockers do.

Basically it's a really complicated open diff and the helical cut gears make it more difficult for the power to be routed through only one wheel, that's the best way I can explain it. Get a big traction/weight difference side to side and it will still only spin 1 tire.
You've got that backwards, it's the inside tire that remains locked with a locker when cornering and the outside tire that's unlocked and as such, it spins faster.

 

Actually, that is only one style of limited slip...... some use the helical cut gears, others use clutches, still others use a viscous coupling.......

For lockers, when they are locked.... both tires turn at the same rate, when they are unlocked, they are essentially an open differential, and the tires can turn at different rates. Step on the gas in a corner, the locker locks, and one tire or the other is going to 'scrub', because the tires are traveling slightly different distances in a corner.

Are we having fun yet?

 

Its a bit of a pain in the *** really. I'm locked in the rear and some times the bang can be quite unnerving while towing. Turns its not to be. I have had mine in for about 4 months now.

 

Lockers are awesome, cant wait til I get one in my truck been looking at the lockright, and waiting on my rear end to blow to convince parents to let me install it.

One of the best things is slamming on the gas going through turns and hearing them lock and the drift begins

 

I'm well aware of the different kinds of limited slips, I was talking specifically about the True-Trac lastrights had posted a link to. The Torsen and Quafie (sp?) work the same as well.

 

Yes, you are right. That's what I get for typing before thinking it out first...
