I have a 2004 jeep liberty. I was recently changing my oil and a friend of mine said that I have a front differential leak. What does it mean and how much should I expect to pay. Further, I am trying to get as much life as of this car as I can so what can you suggest to extend the life of the car. I am going to the mechanic tomorrow and I want to be prepared so I don't get over charged. Thanks.
I have a leaking freeze plug. I recently had the shop put in a new water pump and radiator (the reason for the leaking plug). While they are working on replacing the plugs what other work should I have done? I figure to save time and money I could have other things replaced or fixed before there's more problems.
