Product review (4 stars): Use these OEM ,not the Taiwan copies from Memphis
Can be done w/o special puller . Much easier with Tony tool or check out xtremeskier video on utube.
One of better ones online.  Steel spacer tube between bearings little tricky to hold in place if just driving bearings in.
These Neptunes [no glass door styles] are built better than [samsung / maytag glass door styles] as well as many other later one. Better vibration dampening , and use about 5 gal water. Downfall of newer ones in my opinion is too fast [1000 rpm vrs 800 ] gets dryer but tears themselves apart after 4 yrs or less. Use less than 3 gal ,, Not enough to rinse soap out.
