OK I'm back with another question. So the 325 I got runs great and hardly anything wrong with it, had front engine worked on extensivley a couple months ago, but I notice a deep whirring sound coming from the back when driving. I was told it's the hubs and hub spindles that need replacing...does this sound about right? Is there anything else I should be looking at or replacing while the mech is back there? Also, anyone have a round about figure on how much this will cost me to get them replaced, what can I expect to pay? Thanks again and sorry for all the questions, I just like to hear opinions and facts from people who've been there and done that.
