Um, you might want to upgrade it. The Suburban, Tahoe, and relatives are *very* fragile when taken off road. Their tie rods and balljoints in particular are too small and weak for offroad usage out of the box. The old Jeeps, on the other hand, do not require any upgrades.
no no no no no!!!
I don't do offroad but I haul alot of stuff. My baby's joints and rods are good enough for me!! :)
