Good point, must do mineThis may sound downright rediculous to some but evey now and then i poke stick into the little drain holes in the bottom of the doors and drag out the sludge and junk at the bottom. helps stop rust forming as quickly, you'd be surprised what gets in there, esp on older GQ's
Good points. Also, before you start off at highway speeds again, re-torque all your wheel nuts. This is especially important if you are running alloys. In fact after having one tire monkey mess up and not torque my wheel nuts properly and loosing a tire, I now always check the nut torque after anyone has touched them. Nothing like the feeling when you realize that tire passing you on the road is one of yours.After a good clean underneath I generally check for any damage from sharp pointed sticks and rocks etc, if deep water involved then a bit of extra lubrication and water ingress checks may be needed.
