The rear hatch in my '04 treg was sagging so I replaced the two lift supports with new VW parts but it's still almost as bad. I just noticed the back glass struts are totally shot so I'm going to replace them as well. Are the hatch and glass struts linked together which would explain why the new hatch struts didn't make the hatch stay up much better? Also I noticed the date codes on the new hatch struts were from 1 1/2 years ago. Could they have gone bad from sitting on the self that long?
