The ICON On-Vehicle Uniball Replacement Tool Kit comes complete with everything necessary to service uniballs in ICON upper control arms, as well as other control arms that utilize a 1" uniball. The design of this kit allows for the job to be performed with the control arm still on the vehicle, minimizing the work and time involved with this task. Because a hydraulic press is not required when using this kit, safety is improved while the chance of permanent damage to the control arm is reduced.
