What kind of sounds is it making?

If the sound is noticed ONLY at the end of the spin cyle:

*Thump-Thump-Thump-Thump*

This will be a worn Agitator Drive Block.

This repair requires some level of skill to correct (and possibly one specialty tool)

__________________________________

If the sounds occur DURING the spin cycle:

*Bang/Boom/Rattle/Etc*

This is most likely a tub assy that is not in it's proper position on the superstructure/frame and/or a missing suspension support spring.

To correct this--also requires a bit of previous experience being able to identifying whether or not the tub is out of position on the frame.

The rear spring however---if found hanging---is easy enough to correct with a drill unless the spring lacks a *hook* from corrosion.

Bottom line---this repair can be more than a DIYer wants to tackle. A competent servicer can resolve either fault rather quickly.
