I originally had my 4:10's installed January 2005. They wined so bad I bought another set of gears an had them installed at a different place in March 2005. After doing it 3 times and replacing most of the bearings in the rear end on a car with less than 12,000 miles on it, the guy working on it got the wine out of it. After about a month it started to wine a little between 65 and 70 only. This didn't bother me to much. The guy that did my gears the second time was highly recommened and I am pretty sure he installed them right. When I went back to change my fluid after the break in period he said everthing looked good. After having my transmission TSB done in September, I started to notice the vibration that some of you talk about. I think the Ford place did not put my drive shaft in the way it came out. Is it worth it to get the aluminum drive shaft to stop the vibration and will a drive shaft help with the wine. I have read were some people claims it helps with hormonics caused by the bigger gear. What do you think?

This is why you guys are having this problem AFTER service that requires the driveshaft to come out.
