The sliding mechanism you're referring to (assuming it's a suspension or drivetrain component) usually serves more than just removal purposes. It's likely designed to allow for some movement or flex, especially when the body and frame articulate during off-roading. This flexibility helps the suspension adapt to uneven terrain, ensuring smoother handling and preventing damage to other components under stress.
If it's stuck, that lack of movement could potentially lead to issues during off-road conditions, where articulation is key. Getting it freed up is definitely a good move to ensure everything functions properly when you're out on the trails!
