Powertrax Locker Do you Need one? Front locker, Rear locker or Both

Powertrax Locker Do you Need one? Front locker, Rear locker or Both front & rear lockers ??
The Jeep locker is now installed and I checked it by raising one wheel with a jack and driving it right
off the jack, with either tire. Some people said they were noisy going around corners, but I
remembered an old trick. The trick is to use ultra-high performance fluid (like Royal Purple) and
that is what greatly cuts down the clicking noise. It uses a racket mechanism for complete lock up of
both tires in low traction situations. It is much better than posi-traction.go in the snow & mud, mud
& snow traction,posi-traction. This install was more difficult because it was a Suzuki. The locker
will totally lock both wheels in low traction situations only. A regular vehicle could not drive away
with one tire off the ground. The tire off the ground would just spin and the vehicle would not
move. With the locker, as soon a traction is lost, the internal racket locks and both rear tires have
traction. If you install one locker you want it to be in the rear versus having the locker on the front
wheels where the steering is.
This a full time locker. On the trail having lockers on both axles may be a huge advantage in going
through mud, sand or snow. But when driving on the streets in the snow, a front locker can be
harder to control when you are going around turns and corners. When driving in snow on the
roadways with a front locker, you would be better off locking only one hub and locking the other
hub in a situation where it may be needed. With the rear locker only you will stay pretty stable on
snowy roadways and you might find that the rear locker may be good enough to get through the
snow without using the 4 wheel drive.
