The last little tick regarding my car is a slight vibration that begins at 70-75 and worsens with speed. This is my second Coast aluminum shaft (the first came apart at the slip yoke). Hell, that could be the problem with this one. Word is, the slip yoke design isn't exactly a good one. I'd go with one of these expensive CF shafts if it would cure the problem.
My pinion angle is correct so I know that isn't the problem. Are there other CV joint design driveshafts or cheaper options out there?
Also, any thoughts on what you did to alleviate the vibration is appreciated.
