This is a standard cv joint or half axle youd find in most cars, its created with high detial while keeping the polycount decent. It's a great peice of detial to add to a car model since its uselly well seen from the outside of a car and so often overlooked. I've included two versions of this joint, theres a straight version and an installed version, if you use the morth tool you can esaily blend the bend to fit your car, or easily modify it using soft selection as the geomtry is very clean.
