Washing tool squeaks? I live in a apt. and have have my machine for 5...

I live in a apt. and have have my machine for 5 years and it is a small stackable. It works good and I other keep filter clean. Lately it have been squeaking on and off during cycles. It does not do it every time. Maintenance said it be ok but should I push for a new washing apparatus?
Answers:    the machine comes with the apt?? if it runs next they have fulfilled thier part of the wrangle. when it failes then they will give U a spanking new one.
Hope this helps
oil support whill the squeeking is probably only the tension springs or the snubber pads neither of which is a problem except for the annoying boom
