I am curious, when I had my axle seals replaced. The Mechanic said I should put the center caps on to keep the water from getting in and rusting out the seals. My regular Mechanic said, since it is a sealed bearing you do not need the center caps and they do not stop water or anything from getting through.
I do not like the look of the center caps on the rims, and I agree as to them not stopping moisture from getting in.
I think they are there for looks only, but I liked the look of the rims without the center caps. So are they necessary or not? Thanks
