I like their selection and prices but the customer service is horrendous. The stupid online questionnaire is worthless and will just feed you canned answers instead of resolving issues. See the pic. Rockauto insists the nut on the left is the OEM axlenut. Got the one on the right from Chevy. Guess which one fits? I ve been trying to contact them to help future customers but they deleted my comment on their Facebook page. Never again rockauto. Seriously all you need is a small group of people to talk to customers.
