Fortunately, it's a very easy process.
1.) Remove the pum head from the pump body by removing the TC clamp.
2.) Remove the motor bracket from the pump motor....4 phillips head screws.
3.) Inside the Motor bracket, you will find the cup magnet that's held on the shaft by a set screw...remove that set screw and take it off the shaft.
4.) Remove the 4 phillips head screws from the back...they're long... then remove the back cover.
5.) BEFORE you start pulling the shaft out, note that in front of that front bearing is a washer that's used in take up the slack between the length of the housing and the length of the shaft. Don't loose that because Blichmann does not sell replacements. (They only sell the entire motor body as one unit)
6.) Remove the shaft and then pull the bearings off the shaft. I used an adjustable wrench under the bearing (avoiding the c clip) and taped the shaft lightly with a rubber mallet to remove the bearings. You may be able to just wiggle it out yourself as mine came off very easily. Do the same with the back bearing. Put the new bearings on...they just slide into place against the c clips. (I used https://www.amazon.com/dp/B07VPQZZMV)
7.) Reverse the process and you're good to go!
After doing this, mine was extremely quiet.

I am sure quality has gone down over the years like anything else. In terms of build quality, I can't tell the different in materials used when comparing the riptide pump to any other cheap pump from china. They both use high carbon steel bearings with a plastic seal instead of ceramic or stainless steel bearings. They both use tricks (like the compression washer) to fill in space because the design tolerances are so high. They're all value engineered. I suppose building a pump with tighter tolerances and quality parts would probably cost more than the $250 they're selling these pumps for.
