Whats the fastest you should drive with part time 4 wheel drive?

I have an 00' Cherokee with New Process NP231 "Command-Trac" case. Ive always heard its like 30 in gravel/snow but i can do 50 on snowy roads and the transfer case make less noise than going 30.|||45 mph is a safe max speed, although it mostly depends on road conditions. Patchy snow and some dry pavement can cause problems, especially in turns where you will get binding. Excessive speed cause front driveline problems over time, but keeping it around 45 or under will be a good safe bet. Good luck!|||I can safely drive 80km/h in my 89 Cherokee with it in 4HI, but even then, it is not recommended for extended periods.
