While doing maintenance on my car (VW Jetta TDI 2003) I noticed that the front caliper bushing was not lubricated and decided to buy new bushings and then lubricate them. I bought another brand that was so inferior that the bushing broke when I tried to install it! So I was looking for something else and found these, the reviews were good and I bought them. Installation is a bit tricky, I suggest using a very small amount of silicone based lube to slide it into the caliper, after that use a suitable caliper lube. I haven't driven the car since installing it as I need to adjust the camber but I have no doubt the hub should do its job well.
