I am preparing to re-install the CV-axle on the front passenger side. Everything looks fine except I want to make sure I make the best lubrication and anti-seize decisions. CV-axle = front half shaft axle = front right/left axle. Plan A. 1. Lubricate the C-clamp on the end that goes into the differential with a small amount of grease. 2. Cover the opposite end, the threaded end and splines, that go into the wheel bearing and hub assembly (WBHA) with anti-seize. Plan B. 1. Lubricate the C-clamp with gear oil. 2. Cover the threads with anti-seize but avoid the splines at the wheel ends of the axle. Plan C. Avoid lubrication. Only apply anti-seize to the threaded end of the axle where the axle nut will sit. Questions: Should I add lubricant to the splines going into the front differential? And if so, what kind? SAE GL 80W-90 gear oil? I will be adding the same gear oil to the differential once finished. Should anti-seize be also added to the splines that fit into the WBHA? I seem to recall reading a recommendation to that effect. Copper or nickel-based or does it really matter? Background I took out the passenger side CV-axle because the differential side seal was leaking. The side seal is back in place; new lower control arms (LCAs) are installed with the new wheel bearing and hub assembly (WBHA) torqued into the knuckle. The axle looks fine and did not exhibit any symptoms of a failing or failed axle.
