The Kia Metro Towner has front disc brakes with pads and rear drum brakes with shoes. The factory U joint is not fitted with a grease nipple. We stoke replacement U joints that do have a grease fitting replacing the u joints with grease able joints gives the assurance that the drive shaft will not fall out when you least expect it. The front coil over strut cartridge in this truck has a bushing inside it that wears oval and the internal fluid leaks out causing the truck to bounce or bottom out when traveling over bumps. We sell a replacement strut cartridge that will provide a smooth ride. It is available on our online store.
