If your Toyota Sienna is riding rough or bouncing too much, these new front strut assemblies might be the fix. This 2-piece set includes both left and right complete struts — springs, mounts, and shocks all in one — designed as direct replacements for 2005-2010 Sienna LE and XLE 7-passenger models. Brand is Ubmotor, part number 12M141073074WM0506, with interchange numbers like 172363 and 172364. They come with a 1-year manufacturer warranty, so you're covered. Installation is bolt-on if you're experienced, but a shop can handle it in a couple of hours. New struts can totally transform your van's ride — better handling, less noise, and improved comfort for you and your passengers. Don't wait until they're completely shot; replacing them early can save wear on other suspension parts. These are aftermarket but built to meet or exceed OEM specs. Perfect for DIYers or mechanics looking for reliable, affordable replacements. Make sure your Sienna is the right year and trim before ordering. Get your van back to smooth, stable driving — your family will thank you on the next road trip. A solid upgrade for a tired suspension.
