I sort of chuckle at the idea of airing down to help with darting. I get that we get desperate when we try what seems like everything and it doesn't resolve the issue.
Does it feel like your uncontrollably moving to the right or left, as if you where in a floating boat on waves at highway speeds? Especially when the road sort of has smooth highs and lows?
2 cent EDIT: unless your YJ is a manual, you travel often with kids and or it has no AC, I think the YJ is more reliable. And tougher too. Plus cheaper and easier to fix. One exception to daily driving is if it carborated.
