I just bought the GC a few weeks ago and the hose is completely missing. It's definately GL5 and it's all over the gas skid plate and the bottom of the driver side chassis above where the breather is. I wiped it down good and checked the fluid level (which was full) and drove around a little bit and there was nothing. Then I went on a 1 hour road trip on the highway and about 40 minutes later all you could smell was GL5 and it was smoking of the exhaust.
Soooo anyway, I was pretty sure it was because of the missing tube, but that seemed too easy. Wont the fluid just spray up the hose if I put it on? Is there a more serious problem I should look for that's causing the pressure? I have a limited slip and I'm thinking maybe if someone changed the fluid without friction modifier, maybe that would be part of the issue?
