problem. The lower DU bushing is a common wear area on the Stumpy and FSR. There are common wear areas on any full suspension bike. Parts that have to be replaced occasionally as they wear out. In this instance it is the bushing in the lower shock mount that needs to be replaced occasionally. Now in manufacturing we all know that parts are not always perfect. Now and then an out of spec part will get installed and cause a problem. This is the instance with the current thread on the lower bushing that just popped up I am sure. Specialized makes may hundereds of bikes each year. So occasionally there is bound to be a bad this or that that slips by the QC department. But Spec has an excellent warranty policy, one of the best in the business I believe, and as long as your LBS works it the way they should there should be no problem getting such things taken care of. If it does worry you, you can always have your shop order a new set at the time you purchase your bike. And if you weigh in at 200lbs or more you can have them order the "big boy kit". Don't know what that consists of, but I do know it includes heavier duty bushings, probably a harder material. Either way, it would reduce down time should you have the problem. I know that I have a full season on my SJ and have not had a problem with it in any respect, and I tip the scales at 230. So my guess would be that the original poster in the Bushing thread got a bad out of spec part. As I said, when you produce the volume that a company like Specialized does, there are bound to be a few problems. That's what warranties are for, and Specialized stands be hind their products in an admirable fashion.
