o2 sensor: Denso or AC Delco/ Wheel bearing recs

[radchad3]

Hello all. I am in need of an o2 sensor I am looking at either of these.

Denso: Part # 2344018
AC Delco: Part # AFS109

Are these the right parts numbers? The Denso is a little cheaper so I was just planning on going that route unless someone felt differently about them.

Also I will be ordering a front wheel bearing. I am looking at:

National/Timken: Part # 513087 (These are listed as separate bearings but the same part #)
National/Timken: Part # 513062

Any suggestions on these?

Thank you all for your time! Chad

O2 sensor: Delco. The Denso I had went bad after 30k miles. Not worth it for the price difference between it and the Delco.

Wheel bearing: 513087 is the part number on the box my new National front wheel bearing came in.

Also, if you have an Advance Auto nearby you, the wheel bearing can be had for $103 by ordering online for in-store pickup. Use a discount code to get that price. If it goes bad in the warranty period, then you don't have to wait for a warranty unit to be shipped.
