I think that after just 3 years, my pump motor bearings may be going bad (brand new motor 3 yrs old). I am hearing a loud whining sound coming from motor. Already replaced the impeller and seal, but that did not help. My question is, if I don't have a bearing puller, then by the time I buy the tools needed, plus the bearings themselves, I will have about $100 into it, and seems I can get a new 1hp motor for around $150. Is it worth the hassle to replace the bearings?
Also, if I replace motor, the last one I bought was US Motors from Leslie's and I just read a bunch of not great reviews on these motors. Should I get an AO Smith, or does it matter?
