If you are not getting a warning light on the dash, and are not picking up any codes, then leave them alone.
The only way to find out if they are bad and need changed is when your engine light turns on and you read it for codes like Rowefast stayed.
I have approx: 154,000 on 2004 Highlander and have read somewhere O2 sensors are only good for 100,00 miles then need replaced. What's the scoop?

I have a 2008 highlander base AWD. I purchased it certified used in 2010. It now has 76,000 miles on it and it feels like the ride is getting a bit rough. Do I need to replace the shocks and struts...
