We often hear of customers who have difficulty installing our Spherical Sealing Boot onto our CV. The reason why you may run into trouble is the CV boot fits so tightly it creates an air lock inside. If you take a zip tie and slide it between the CV and the boot, you can install any size boot with ease by hand! Shown here is our new larger Jeep Dana 44 CV boot for the 2018+ Jeep Wrangler JL Rubicon.
