"I also scraped a few rocks in that boulder section at the start down the creek trail. I don't seem to have suffered any damage from the rock garden, but I was a bit nervous after scraping the ledge on argentine pass earlier in the day. I found it challenging to pick a line in the large boulder field -- probably lack of experience. I followed Bob down, and was impressed with the clearance his GC afforded him in that section."
When we looked at the x-member at the bottom of Argentine, it was very minimal scraping - sometimes it sounds worse that it really is. Old rule of thumb...put the ugly stuff that is sticking up high and could be a clearance issue under the right or left tires when possible. Obviously, when clearance isn't an issue, we choose the smooth line straddling the rocks, but if it gets a bit ugly, sometimes the bumpy line with the higher rocks under the tires is better for clearance. If you put your tires on the high stuff, it raises the rest of the vehicle and provides more clearance. Sometimes, the high rock is right in the middle of the trail and its not possible to put it under a tire - so then it helps to know where your differentials are located. On the TJ/LJ, I believe the rear diff is centered between the tires, and the front diff is on the right side, so that means if you have to straddle the rock, try to have it go under the driver seat. Take it slow and a little bump often won't hurt anything - if it stops the vehicle its time for a spot. Following someone like Bob is also a good way to learn (I've seen him take some stock and lightly modified vehicles on some tuff trails) - it doesn't take long to get a feel for exactly where your tires are, and to begin seeing the 'line' or route through the rocks.
