If I read correctly, it sounds like the student has simply a bit of an attitude problem, but was as much of a contributor to the team effort as anyone else.

It'll come down to a personal call of some sort, but I don't think it sounds like there's reason to change the drive team simply because team members don't like the person.

Our team worked with two drive teams, and there were obvious differences in levels of skill and experience between them, but we did it because we have a small team. You have a single drive team with a proven track record - go with it, and work out the interpersonal kinks on the side.
