I think ours is on it's way out

we rent and it came with the house, so luckily isn't our responsibility to fix! It's always been quite noisy, but today it's really, really noisy! I think the drum's coming loose as it shakes a lot when spinning, but now it seems to be making noises when it's taking water in? I don't know how to describe the noise really!
Is there anything I can do to try and fix it, or should I call the landlord? Typically I've got a weekend's worth of washing to catch up on and all the towels need doing! Sod's law
