Invacare Aviva Storm RX20 front casters issue and fix

Aviva's casters fix I am happy to report that I have fixed the Aviva's casters issues. Now the casters swivel easily, smoothly and silently. The nose heavy feeling is gone. The Aviva feels like a new chair. I purchased the: $10 - Thrust Needle Roller Bearings 0.75 Inch Bore 1.25 Inch OD. You only need two per chair. https://www.amazon.com/dp/B09CG2TFJM another cheaper option $6 https://www.amazon.com/NTA1220-Thrust-Need... They fit the forks shaft perfectly. The bearings are 4mm thick so you can't over tighten the nyloc nut on top. Tighten it until all vertical play is gone and the fork swivels with little resistance. I kept the bronze spacer and wave washer in place and just put thrust bearing on top of them without adverse affects. I added some Hi-Temp Grease. Any gear grease will work. Hope this cheap and easy fix will work for other Aviva owners.
