here's also my signature.........
Ooops... Your correct I did mean 2x4.
I did more testing this past weekend and had mixed results. As before the normal straight up hill pull was awesome. Both tires pulled together and strong just like a locker. The thing that really impresses me is that the system seems to act much quicker than any conventional clutch type limited slip i've ever tested. In most all cases there is NO one tire wheel slip in order to get the unit activated. I can tell this by driving the truck and having someone look at both tires while outside of the vehicle.
Now for the problem:
The second test involved going along side a deep rut and turning directly into it in order to get one tire in the air. I did this knowing this a weakness of this type limited slip. In this situation when one tire has much less traction the system sends all power to the tire with least traction. Anyway, it did as expected and only spun the tire in the air. Surprisingly, i also heard a horribly loud whinning or squeal coming from the differential. At this point i'm worried that something is damaged or the unit has been installed incorrectly. Thinking maybe I did something wrong I tired once more but this time I also applied the brake (not parking brake) and still had both the noise and one wheel spinning problems. At this point i'm very disappointed and decided to head home.
The next day I contacted TracTech and was asked if i was using a synthetic based oil. I told them yes and that it was Aimsoil (spelling?). He told me that I should use NON-synthetic oils only and that changing the oil would solve the problem. Apparently, synthetics cause most LS units to do crazy things and that normally they are not recommended. This didn't sound like a fix to me but I decided to try anyway. As for using the braking manuver for one wheel in air situations he said to use the parking brake instead of the main brake. To do this correctly you should gently apply the gas and slowy start clicking down the brake until you notice full lockup. At this point leave the brake in that position until you are out of the situation. This allows braking for only the rear tires which allows the vehicle to still move while the brake is applied. I felt a little stupid on this one as it made perfect sense.
Now for the final test:
I went back to the same spot and the results this time were AWESOME. No noise at the differential and by using the parking brake I had full lockup and made it out of the rut without using 4x4. It is truelly unbelievable how much better your truck will go with these units.
