I have the bad box but my jeep drives ok with it. It's probably not nearly as bad as some with maybe about 1/2" dead spot. I do find myself correcting slightly tho. Any here that don't really have complaints with it and will you just keep the old box or at some point before the warranty is up...
One never knows when your number is up. I had a comanchee and soon as I heard about the gladiator it was a must have. Like they say...life is too short to not enjoy it.
I have to wonder if they at least adjusted the new box...also wonder if they adjusted the old box after the complaints and is why some aren't as bad as others.
