How hard is it to replace the tire pressure, slip and abs censors? I'm having a few minor issues with sensors my '08 Titan 4x4. It starting when the air pressure warning light flashed a few times and has been on solid ever since. The air pressure is fine and the book says if it stays solid it's a sensor. Not much longer after that the abs and slip lights came on. I'm fairly certain it's because of some heavy duty rust.
Any advice is greatly appreciated!
