My dryer squeaks when I firststart it then it slowly stops. HELP

Oscar28:::-IT could be the belt that turns the drum or the tension whell down at bottom ,or it is possible that where the drum axels (SHAFTS) are on front and back that holds drum in place . I have found onseveral dryers that from the heat, in dryers causes the lubercant they put there when built dries, disapeers, but the squeling starts, I used to when I found it comeing from this area, I would put 3in1oil(a few drops)on front and back, it would stop for some time. I gave 3 susgestion, I hope One of them work .::: GOOd luck :::: F.B.E.
