rod bearing replacement with engine still in the car?

[spdcrazy]

i need to search further to make sure it is a rod bearing, but i have a rattle in the engine from about 2300 rpm to 3300rpm's. if so, i should be able to pull a spark plug wire one at a time and single out the cylinder/s that need new bearings ya? then can they be replaced with the engine in the car? just drop the oil pan and replace?

Might as well just replace them all, they're inexpensive. Yes, drop the pan and you will have easy access.
