crank bearing replacement

[NationalGN]

hey all, does anyone know if i can replace worn out bearings on crank with it still in car?

The car has 78,00 miles on it bearings are slightly scratched.

Yes, you can

I'd be more worried about why they are scratched with only 78,000 miles. Something is in that motor that needs to be cleaned out.

If they are scratched debris went through them and is probably embedded in them. If the debris is still in the engine it will do the same thing again. Bearings are not wear items.
