Does it make sense to make the exam grading very transparent

Is it advisable (in terms of the benefit for the students and the work it causes) to make the grading completely transparent to students? I think for instance of publishing the sample solutions for the exam or the distribution of the grades given. Would those measures be suitable to convince the students that the grading is fair or would it rather make worse students feel treated in an unfair way and trigger many complaints. As far as I understand the University lets normally now the students only their individual grades. Of course they will always compare themselves in smaller groups.
