Rebuilding this joint is not much different then a single as there are just two of them. So I would start with the inner joint closest to the drive shaft.

Once they are separated it is just a matter of replacing both joints and then putting it back together as seen in the pictures below

Plus below is the inspection process for this as well. Once you rebuild them you will want to check the operation on the vehicle to ensure it is not binding.

Please let us know if you need more info. Thanks
