Hi Marla,
noises due to lack of lubrication are funny... My 380SL was making a "dry bearing" noise when the temperature here dropped below freezing. I took the AC idler pulley off and lubricated it with a grease "needle", but it continued to make the noise until the temperature warmed up again. Now the noise is all gone! One thing you can be sure of is that the noise is a precurser to further problems. So, I think it would be very advisable to take it in to a good alignment shop and ask them to give it a "once over" to check for worn or damaged parts, concentrating on the passenger side front. Whatever they charge will be worth it in your peace of mind.
