So these WEDOAUTO tie rod ends are direct replacements for the ES3461 part number and they come as a 2-pack for both the driver and passenger sides. They fit a bunch of vehicles including Ford Explorer from 1998-2003, Ford Ranger from 1998-2011, all the Mazda B-series trucks like B2300, B2500, B3000, B4000 from around 1998-2009, and Mercury Mountaineer from 1998-2003. Before you order, definitely double-check that these match your original parts by comparing the pictures or OE numbers since installation instructions aren't included. Speaking of installation, this is one of those jobs where professional installation is recommended unless you're really comfortable working on suspension components. The good news is they come with a five-year free replacement warranty, which is pretty solid for auto parts. These tie rod ends are crucial for your steering system - they connect your steering rack to the wheels and when they wear out, you'll notice loose steering, uneven tire wear, or your vehicle pulling to one side. If you're experiencing any of those issues with your Explorer, Ranger, or Mazda truck, these replacement tie rods should get you back to tight, responsive steering. Just make sure to get an alignment after installation to prevent premature tire wear.
