Does fuel filter need to be changed?

Q: I have a 2011 Mazda Tribute and wanted to change the fuel filter. The manual states that it is in the gas tank and does not need to be changed. I find this strange, so I asked my local mechanic if he knew about this. He looked up gas filters for that model at his supply store and it shows one. I told him what the manual stated, but he said he believed that it does have a replaceable filter. Do you know what is going on? — E.D., Ft. Lauderdale, Fla.

A: The filter on the fuel pump pickup pipe in the tank is all that most cars have today. But your Tribute has a second, external filter located near the fuel tank. It is replaceable, but I have not heard of any getting clogged. (Maybe I should have my hearing tested for wax buildup.)

Q: I have a 2003 Jeep Liberty with 142,000 miles that is in very good condition. I have not been able to locate a squeaking sound that I think is coming from rear suspension. I have replaced all the shocks, struts, springs, and upper and lower spring isolators on the rear shocks. Noise went away for a while but is back. I was thinking about lubricating the control/suspension arms. What lubricant would you recommend? Do you have any other suggestions? — J.M., Plantation, Fla.

A: Squeaks and rattles often get the sunshine treatment. (They leave the vehicle outside until you return.) I suggest spraying all the rubber parts with silicone lube and the metal parts with oil or a penetrating oil. Start with one or the other to whittle down the source of the noise. My hunch is a rubber part.
