Drive shaft angle is set by the relative heights of the drivetrain components, especially the connection between the transmission output and the final drive. When those mounts sit at the wrong heights, the drive shaft runs at an improper angle, which can cause vibrations and U-joint wear as the suspension moves. The controlled way to adjust this is by adding or removing shims under the transmission rear mount or under the final drive assembly to change their heights and set the drive shaft angle to the proper specification.

Replacing the drive shaft with a single-piece shaft isn’t an angle adjustment method; it changes the drivetrain configuration and may introduce other fitment or alignment issues. Loosening all mounts and starting the engine isn’t a precise or safe way to set angle and can cause components to move unpredictably. Tire air pressure affects only ride height minimally and won’t correct the drive shaft geometry.
