I just bougt my 99 4runner like 2 months ago and was wandering if there is anything that is known to go bad on them. So far I know timing belts and water pumps, I have always noticed the rear sag but I dont think 99's had that? either way I believe it has a lift/leveling kit because parked beside 4 others and mine sits a good 1.5-2 inch taller front and rear and sits straighter. If anyone has any ideas it would be great appreciated! Thanks
