If its the front propshaft
Front CV joint uses graphite CV joint grease. When you remove the prop from the IRD flange there's a metal shield that you have to lever off to get access to the joint, the existing lubricant on mine had turned into a thick oil and piddled out all over the floor so make sure you have a bucket under it.
mine is slowly spraying itself over my floorpan. Winter protection i call it. Must get it done soon though
