A clunk over bumps, fluid on the strut body or a bouncy ride can mean the strut is worn, though a tired strut mount or coil spring can also be behind those signs, so pin down the source before buying. This listing is one strut; the front axle takes one at each wheel, and the pair is normally replaced together.
Fits
This front strut fits the 2005-2023 Toyota Tacoma, the 2003-2024 Toyota 4Runner and the 2007-2014 Toyota FJ Cruiser.
