Work on strengthening the weaker leg in isolation, along with activation exercises such as tkes and glute/calf isos. You may find that the weakness is caused by a firing issue more than an actual strength issue.
Doing low box drops and really focusing on landing perfectly is extremely important. Get this down first, then move on to jumps. The landings will help you focus on both landing safely and getting into proper position for takeoff once you perform a regular jump.
All that being said, Im assuming youre mainly referring to your svj, as a rvj will have different force distributions between legs anyhow, and at completely different joint angles during the rom.
