If my wife applies for an individual loan, is there any way she can claim my income?

My wife and I would like to get an auto loan, however I have TERRIBLE credit! She on the other hand has good credit so I was thinking she could use hers to apply for an individual loan without me.. Only problem I've found is that she has no income to claim since shes a homemaker... I on the other hand make about $2800 a month and we are seeking a $20,000 loan... Can someone tell me how to make this work? Thanks!
