If you're hearing clicking noises when turning or feeling vibrations, your Volvo XC90 might need a new CV axle. This is a complete front right (passenger side) axle shaft assembly. It's made to fit Volvo XC90 models from 2007 through 2014. It replaces OEM part numbers 66-9344, 36000515, and 36001221. The compressed length is about 40.24 inches (1022 mm). It has 28 splines on the input shaft (transmission side) and 40 splines on the output shaft (wheel hub side). It includes all necessary boots, joints, and hardware for a complete replacement. A quality aftermarket part that can save you a bundle compared to dealership prices. Always a good idea to replace both sides if they're high mileage, but this one gets the job done for the right front.
