Outer seals degrade when they are exposed to contaminated engine oil for long periods of time.

You may want to replace your dual row bearing before replacing the clutch if you haven't changed oil frequently (once a year or every 5000 miles whichever came first), you've let your car sit for long intervals between drives, or you/ve tended to take many drives where the engine hasn't run for 20 minutes or more at operating temperature.

If you're worried, replace the bearing now.
I change the oil every year. I hardly use the car, sometimes it sits in the garage for about 2 months. When i change the oil my mechanic jokingly tells me that he feels like selling my old oil to someone else, as it's colour is that of brand new oil,sometimes with as little as 500 miles on it.
I still make it a rule to change it every year though, and inspect the magnetic drain plug and oil filter really well.
So do you think i should change the bearings because i don't use the car much?
