I got in with the Stormcloaks and completed the Crown quest but the Jarl still hasn't made me Thane of Windhelm. Am I missing something or is it a game glitch ? Edit : Finally got the Windhelm house. I completed the Windhelm murders quest (not sure if it's needed but since the murders were commited inside the house...) I also competed the Fort Neugrad Liberation quest. It was after that quest that I was offered the house.
