Partial Least Squares regression, principle components analysis or remove one of the variables.

You can't "remove" multicollinearity from your data. It's in there, its not going away.

 

You can analyze the data in such a way that the multicollinearity has (hopefully) little effect on the results. One method is called Partial Least Squares regression, or PROC PLS in SAS. Naturally, this works only in a regression situation, other types of analyses call for other methods.
