If you have already replaced the inner and outer CV joints, the drive shaft, and the differential in the gearbox, yet the vibration on the left drive shaft persists, there are a few other potential causes to consider:
Wheel Bearings: Faulty or worn wheel bearings can cause vibrations, especially during acceleration. A failing wheel bearing on the left side could be the source of the vibration you're experiencing.
Engine or Transmission Mounts: Worn or damaged engine or transmission mounts can allow excessive movement of the drivetrain components, leading to vibrations.
Axle Shaft: There may be an issue with the left axle shaft itself, such as an imbalance or other damage.
Suspension Components: Problems with suspension components, such as control arms, bushings, or struts, can also cause vibrations during acceleration.
Wheel Alignment or Balance: Incorrect wheel alignment or unbalanced wheels can create vibrations that are felt during acceleration.
Drivetrain Alignment: If the components of the drivetrain are not properly aligned or installed, it can result in vibrations.
Since you've already performed multiple repairs and replacements related to the left drive shaft, it's advisable to have the vehicle thoroughly inspected by a qualified mechanic who can check for the above potential causes. They may also perform a detailed inspection of the drivetrain and suspension components to identify any issues that might be contributing to the vibration.
Additionally, the fact that the problem started after replacing the gearbox could indicate that there might be an issue with the installation or alignment of the new gearbox.
