The next day we lined up for Hell's Revenge. I was excited to show this tril to Julie as it is, in my opinion, the prettiest trail in Moab. It is "signature" Moab with the sheep drops nex to the trail, the steep climbs and the off-camber stuff.
Most of the day went off without a hitch. A guy from South Dakota was following me in a 98 with rear locker and no TRAC. After a couple of ledges I asked him how the locker was working and he said he had not used his yet.
I was still fooling with the Trac system and rear locker combo so I decided to stop using the Locker and let the TRAC system work alone.
It was amazing to me, and there is nothing scientific to back this up, but once I stopped using the ARB, the TRAC seemed to work much better. It seemed to me that the ARB in the rear was throwing off the computer and was overcompensating in the front since the rear was not slipping due to the locker being engaged.
After that, I pulled the ABS fuse and tried some stuff open and with ARB only.
I liked this a LOT better than with ARB and TRAC in combination.
I think (personal opinion again) that the TRAC would be great on snow or slippery roads, but in rockcrawling it seemed to be overworked, especially when the ARB was on.
Again, another caviat, I wheeled 2 days with the FJ Cruiser and the 2007 version of the TRAC seemed to work much better than my 2001 version.
Where my TRAC would let the tire slip 1/4 to 1/2 revolution before catching, the FJ's system would ony let it slip an inch or so. It seemed to be a much "smarter" TRAC system.
I think the BEST thing and the easiest thing on the drivetrain would be to ad another ARB to the mix. That would eliminate all the banging ang whacking the TRAC does in the front.
My 2001 has 4 spider gears (commonly refered to as 4 pinion design) and without that, the TRAC would rip the ol 2 spider design to shreads. That is a lot of stress on the spider gears as the front locks and unlocks when a tire leaves the ground.
With IFS, the front leaves the ground A LOT. That said, the ARB would eliminate all that when engaged and you would not have to "pull the plug" on the TRAC.
I followed a locked 80 most of the day on Hells Revenge and by the end when I was running one locker and no TRAC I was doing stuff as easy or easier than the 80.
