Joints are nice & tight and rubber boots are well sealed. These rear links do so little work that they mainly fail from corrosion rather than wear. The steel cup washers will rust quite quickly, so apply a generous smear of grease after assembly. Compared to other brands at 2x the price, you can't really go wrong with these. They aren't the higher-quality meyle HD items, but they will still last a good lifetime.
Took my old 1s off the hole is really big didn.t think the rubber bushes would cover it so used 2 repair washers each side so the rubber was more solid ...other wise a good product
