Noticed some oil on the driveway yesterday so jacked up the Deville to look for the leak. I found a slow like on the oil filter adapter at the bottom of the gasket

I also found some oil on this part of the engine. Not sure the name of that part but it was on the passenger side

While I us underneath the car I noticed green grease coming out of the CV Axle boot

I already ordered a oil filter adapter gasket from amazon and also a oil sending switch.

I am not sure what to do about the other oil leak under the engine. Wondering if it can be fixed at home or if I have to take in to a shop

The CV Axle boot green grease is also something I am not sure about. I see they can be replaced with aftermarket Axles but If there is a way to rebuild this one I would like to fix it. There are times that I here a popping noise from the drivers side front wheel so I figured something was wrong there. I already replaced the wheel bearings and tie-rods on this car.

The oil under the engine looks like it's on the bottom of the head. Probably seeping from the cam cover maybe? Anyway, it doesn't look like enough to worry about.

The CV joint boot appears to be dry. The grease looks like it might be seeping past the strap clamp. It requires a special crimping tool. I'd find a shop that has one and see if they can reclamp it.



OR, you could replace it with a big screw type hose clamp. That worked for me once.

So the popping noise isn't a problem. I figured something is about to fail since there is a vibration coming from that side at speeds over 75mph. I have new tires and wheel bearings. Is there a way to rebuild the internals of the cv axle? Where can I find a rebuild kit?

A popping noise may well be a bad CV joint, but I believe it is usually at slow speed turns.

It is FAR easier and less messy to replace the entire half shaft than to try to rebuild the CV joint, not to mention that you will need some special tools.

I might as well replace it. Which brand is recommended? The CARQUEST CV Shafts New CV Axle Shaft Assembly from advance auto are not expensive but I am not sure of the quality. I have read good things and bad things about most of the aftermarket cv shafts including oreilly's, napa, and autozone. OEM is too expensive for me

I have no recommendations other than stay out of AutoZone.
