    replace bearings vs new motor?

    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?

    Harbor freight has the pullers for $15 and bearings are ~ $10 each online so I just replace them when they get noisy. Use sealed vs shielded to improve the life. Way below $100.

    Ok, that is good to know. So, other than the bearings, is there anything else that can cause a loud whining noise? Almost sounds like metal rubing metal at high speeds. Hate to go through the trouble to replace them, and have that not be the issue.

    It could be the armature hitting the windings due to bad bearings or something inside coming loose. Usually bearings are a high pitched whine/squeal.

    First I thought it was bad impeller but after replacing it didn't solve. Then the pump stopped working so I bought a new one on amazon and it works great. So much quieter than my old one even before that sound started.

    That's a Very common noise when front bearing goes bad. Not sure why you replaced impeller instead of following advice here but for the above poster, I'd focus on doing a bearing replacement (along with seal/o-rings). I've rebuilt mine twice now on my 12 year old pump.

    Where would I be able to buy bearings and seals to replace for a noisy Jandy 1.0 hp Stealth SHPF pump? Any recommended online shops? Or go local?
