noisy washer

Washer is very noisy while washing, not bad during spin. Repairman said we had a bad bearing, and a small leak inside washer base. He said it was’nt worth fixing, this washer is only 4 years old. I would like to try to change it out but I wonder if I need the special tools I’ve seen on this site. Repairman said the Maytag had Amana guts:( , also,can’t find exact model #on this site. Let me know if I should proceed. Thanks.
