Over the years i have replaced hundreds of C/V axles.So i was going to post a how too maintain the c/v joints.These joints are a part of the axle that takes all the abuse
Under the C/V boot the C/V is highly verstal joint with cage and balls.When the c/v axle is running it gets hot.So the cheap Chinese grease goes bad.It loses its lubricating property.And then turns in to a black gunk.The picture is what your c/v joint looks like now .So i recommend you clip off the metal clamps slide in the boots
to the center of axle if they are in good shape.Then start getting some brake clean and a brush and rags because it going to be a mess inside of unit.Let everything dry so no cleaning products are left behind.It drys up quickly then get c/v boot clamps autozone.Then repack with a good grease we sell desert gold grease.This makes the c/v joint run 20% cooler than a new c/v axle .If a boot rips it has to be replaced immediately!
NOT PRETTY LOOK DOWN!
