Funny you should post this today because I just did a cleaning and oiling to my Brother for the 1st time since I've had it! :oops: I would suggest just taking off the casing and oiling anything that moves. Certain screws too. I did just that and I had a squeak still and found it to be in the bobbin casing. Also be sure to clean the feed dogs. I just read again where yours is computerized, can't help you there, sorry! GL!
