Is it ok to stack washers on the CV axle for some reason I only have a spacer on the driver side and not on the passenger side and I can't find one anywhere
Are you talking about the washer behind the axle nut? If so O'Reilly's usually sells them, they are just called a washer. You will find them in the "Help" stuff or it will be with the "Dorman" stuff behind the counter. Some CVs dont have any they use a flared nut that acts as it's own washer.
