When separating the CV axle from the transmission or transaxle, a seal that contains the fluid may be disturbed or temporarily unseated, causing a small amount of oil to leak or drip out from the connection point.
It's essential to check and top off the transmission fluid level after servicing or working on the CV axle to maintain proper lubrication and ensure the smooth operation of the driveline components. The owner's manual or maintenance documentation of your vehicle will typically provide information on how to check and replenish the transmission fluid.
While a small amount of oil leakage during CV axle removal is generally normal, excessive oil loss or continuous leaking should be addressed. If you notice substantial or persistent dripping, it's recommended to consult with a qualified mechanic or refer to a technical repair guide for your specific vehicle model to ensure proper servicing of the CV axle and transmission fluid system.
