I'd contact Tamron Tech Support. These are not cheap optics and they are assembled with precision. Opening the lens could cause contamination or further damage resulting in an even costlier repair, if out of warranty. Most Tamron lenses are covered by up to 5 years of warranty - provided you haven't opened it up - or abused it.
