Good Day: After replacing one idler pully, I am pretty sure my engine noise is now the water pump bearing. There is a little play in the shaft. The Parts Store shows three brands as replacement parts. They are Laso, Graf, and Hepo. Is one better than the other?

Also, it appears if I get the correct sockets the repair should be pretty straight forward. Any tricks, I should know about?

Thank you in advance for your advice!
