s13 ka24de rod bearing HELP !!

[hybridtuner27]

I have a 93 coupe and im in the process of putting a new timing set and i also had a rod start knocking so i was going to replace the bearing as well . I cannot pull the motor where i live and do not have anywhere to do it. I basically have everything unvolted from the engine except bottom timing cover and oil pan , can i change the rod bearings without pulling the engine from underneath the car without unhooking the timing chains , or just in any way possible? I really need to get this car back together as its my DD and im borrowing a car right now , any ideas would be great ..

Thanks

Chris
