My understanding is that those are called lateral rods by Isuzu in the manual. In steering terminology the center link or I believe upper link is the long rod that connects to each inner tie rod end, the pitman arm, and the idler arm. So I made an assumption that lower links were the name for the tie rod (also called an adjuster sleeve). Without those lateral rods (that your calling lower links) if you hit the gas your rear axle would go flying out your front end and you'd be staring at it. Those lateral rods ought to be called push rods ha ha ha cause that is exactly what they do. They push the vehicle forward or pull it backward.![]()
