Let’s talk grease on CV joints. A grease leak is the first symptom that is most commonly associated with a bad or failing CV boot cover. Over time, with exposure to the elements, a CV boot can become dry and brittle, so they crack and tear.
When a CV boot cracks or tears it will usually leak grease onto the inside of the wheel and front suspension. Often times the grease can also be flung onto the chassis or even the lower exterior of your Volvo as the CV axle turns. A torn boot can also allow dirt, debris, and moisture to enter the CV joint, which could eventually cause it to fail.
If you also notice vibrations or a clicking noise during turns, you could be in for a complete CV axle replacement. But first things first:
