Ok so first the issue. I have a clunk sound during low speed left hand turns. After inspection I've come to the conclusion that its my driver side axle... and for some reason the previous owner replaced the original axles with junk yard axles... noted by the white paint pen marks on them so I've decided I'm gonna change them both.

So now for the question. I can only seem to find upgraded axles for the rear and not the front. Why is that?
