how to install engine bearing on 2003 dodge caravan

What bearing? rod? main?

i've got an oil light that still comes on after changing sending unit and a reply said an engine bearing could be replaced without pulling the engine.the car has 221000 miles on it ,still runs good but i dont wan't to tie up a lot of money in it.

You have to remove engine to replace engine bearings that would effect oil pressure. so your looking at a rebuild

thanks, iwas afraid of that.

Have oil pressure checked with mechanical gague see what psi is
