found grease

[Dave]

Hello All,

I was under my '01 coupe yesterday cleaning the underside of the car when I found quite a bit of grease (blue-green in color, covered in black dirt) on the frame above the drivers side rubber boot of the halfshaft (closest to the rear end). There was also some on the alumnum subframe below (just a black film). I bought the car last summer and this is the first time I have been under it. It now has 14K miles on it. What's funny is that the boot itself was relatively clean and the are no visable tears and the clamps seem to be in place and properly seated. It doesn't seem to be rear end grease. It's thick, like chasis grease. Like a grease you would use on a grease fitting for a ball joint.

Can anyone telle what this could be from??

Thanks,
Dave

Hi Dave -

Sure sounds like grease being spun out of the CV joint on the halfshaft - that is the only place there is an appreciable amount of grease back there.

You might get out the cleaners and get the car up in the iar to clean an inspect that boot more closely - this thing gets spinning pretty good, so if there is a small opening in it it will spew at higher speeds.

On of my friends had this same "feature" on his C6 coupe - we noticed what you did, the grease slung all around on the underside of the car and on the suspension components - and some inside the wheel barrel.

Good luck -

best regards -

Thanks mqqn! I'll take a closer look. Is there a grease fitting? I'd like to add grease to the joint.

Tanks,
Dave

HI there,
No fitting, but you might be able to tighten the clamp that holds the boot to the axle.
There is a special tool to do this.
It is called a CV boot clamp plier.
