The 2018 Toyota 4Runner comes in a number of different configurations, but across all of them, the windshield wiper sizes are the same. This model year requires the use of a 24 inch driver's side wiper blade, and a 20 inch passenger's side wiper blade. This is the same on all 2010 and newer 4Runners, while those between 2003 and 2009 used a 22 inch driver / 20 inch passenger, and those in 2002 and earlier used a 17 on each side. The replacement, if needed, is relatively simple. Though most auto parts stores will install blades for free with purchase, even if You order somewhere like Amazon, even the greenest novice should be able to complete the job in no more than 10 or 15 minutes.
