My right-sided, outboard CV boot has started to leak a small amount of grease; I recently had the left-sided boots replaced by the dealer (at some expense, because the outer boot was leaking on that one as well). The arrow on the picture below indicates that the grease just appears to be leaking at the end of the boot before the bearing housing. There doesn't appear to be any tear in the boot itself, and there doesn't appear to be any easy way to tighten the retaining bands on the boot, or make the seal against the housing any tighter.
When I took my car into the dealer for the left-sided leak, they told me that the high lateral g-forces on the track were probably causing the problem by forcing small amounts of grease out through the end seam. They felt the only way to fix it was by replacing with a new boot which would fit tighter on the axle.
With all the 987s on the track, I'm surprised that I can't recall seeing this problem reported before. Has anyone else faced this issue, and if so how did you deal with it? Any other recommendations?
