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.
