Default bad CV joint?

Well i was driving home one night when i heard a clunking so i pull over and my water pump is swiveling...i also notice alot of grease. I go home and replace the water pump and the car runs fine. now im starting to get somewhat hard shifts at a time and no real power to the wheels at some points until i WOT it. I took it to a friends and looked at it and his dad said probably a split cv joint and you need a new boot. Is this correct? advise and part links would be kindly appreciated

Do you hear this clunking noise when you are making turns - namely, in parking lots and places where you will be turning the wheel far in one direction when making a turn?

how about just take a good look under there and check the boots?

if there is grease around from a torn boot....ohhh, you'll see it.

Yeah, it'* pretty obvious if you've a torn boot - molybendium grease is thick and black..looks kind of like you ran over wet tar and it splattered all over your wheel well with accompanying wicking grease stain.
Torn boot or not, even if you had shattered your CV, the hard shifts and no power until WOT sounds totally unrelated. (w/o a LSD, broken CV = 0 shifts)
You mentioned that your water pump needed to be replaced - what caused that situation? Was the bearing just worn from time? Had it seized? Was your car running hot when you noticed its condition?

i don think the two were related. I had just checked under the hood and saw the two. The bearing went out im guessing over time since it has 104,000 miles on it and then after driving back home on it, it had seized after clunking for a while. The grease that is coming out is green and i really dont see alot of black if any. It looks as if the boot was torn and flopping grease but i cant really get a good look since of lack of time.

The displacement is bipolar since it works fine usally and then sometimes just goes out like the joint is coming out of the tranny (quoted from friends dad).

add on: when it is cold in the uber cold in the morning since i did not drive it since like 6 the last day. The SES light comes on for a moment but once the clunking, ect. stops, then the light goes off at next start up.

CV joint grease is not always black - it could be green. Anyway, if you have a torn boot and continue to drive it even though it is clunking, instead of paying $59.95 for a rebuilt half shaft (drive axle), you are gonna be looking at $500+ for a good used transmission. (Not counting any labor!!) Techinfo tells how to change a drive axle.

Also, after you change out the axle, (if it is bad) get the code pulled so you will have an idea what is wrong. Most parts houses will pull the code for free.
