I purchased one of these for my '89 LX a couple years ago. It had developed a nasty drivetrain vibration that rattled the entire car. You could feel it in the clutch as well. I bought this driveshaft during a visit to CJ's and had it installed that day ... Drove it home that day, noise and vibration was GONE. It was shocking how much that did over the stock driveshaft. I'd suggest one of these to anybody who develops drivetrain vibrations.
