Hi my wife bought the truck while i was deployed. when i got home i seriously underestimated the truck and now i love it. Its a 97 he with the 4.0 i do take it off road and it keeps up with more than it should. but today i took it up this big hill it was dry dirt and i krept up it but when i got to the top the truck was overheating so i shut it down let it cool and added water. i drove it onto base and the bottom end let go and started knocking so i towed it home and now im looking for info. is it common for these trucks to get hot when going up steap hills? Im in the U.S. anyone have any sugestions on where to locate the bottom end parts for the truck at a decent price or sugestions on affordable upgrades for the engine i wouldnt mind going to the 4.6 but i still am new to the truck and dont know the drawbacks. Thanks for the info and i got to admit these trucks are in a leage of their own if you ask me.
