Main crankshaft bearings

[TalonEH]

hey guys i was just wondering if it is it possible to change the main crankshaft bearings without pulling the motor because there kinda hard to get to from just taking the oil pan off???

It's possible to do it in car, but your gonna have to take the oil pump/transmission off to do it. Easier to do it out of car but if you must.

ok thnx, i geuss ill just change the bearing on the bottom because the top ones are fine i just dont want to reck my engine because i didnt change them all, but i geuss ill change the bottom ones, will that do anything if the top stay the same and i change the bottom or do i have to change em all??

Half ass job = half ass results . Change them all , do it once .

Either replace top/bottom or dont do it at all. Whats the reasoning in doing this anyway?

one of my bearings on the bottom has a big groove in the middle and is causing a "knock" in the engine so i need to change it

Is the crank grooved or scarred?

what brought this oil problems??? in my n/t it had mad low oil pressure at idle from worn bearings.... You say yours is knocking huh? maybe it got loose some how???? that doesnt sound good though because it could cause more problems later one, id just do it right the first time and replace them all, if you can do it yourself then the elbow greese would be worth it, but taking it somewhere else trust me, i know its mad expensive.... good luck, let us know your results.
