if the passenger side of the axle reached temps in the 1100 degree range and the driver side only reached temps in the 800 degree range then how do you determine anything???
3 known factors are a must to heat treat steel..
1) type of steel
2) hardness desired
3) proper heating then cooling technique based on 1&2
since most of what you have (for jeep parts) is going to be forgings, castings and mild rolled steel it's going to come down to what has the best chance of not being damaged from extreme heat.
The real downside to your scenario is that most likely there are number of parts that "got real hot" and then were partially doused by water and cooled in a very unstable manner....so anything that might "look fine" could very easily be brittle and fail once under stress.
Sorry about your Jeep....it sucks for sure....but don't let saving a few bucks by trying to salvage things end up costing you a whole lot more down the road.
