Has my CV gone bad

[pedalpusher90]

Hey guys a few nights ago i heard a metallic snap when i pulled forward slowly twice, and now I have a thumping when I drive. It thumps when i drive forward, turn right sometimes, and sometimes when I turn right it does not knock until my suspension compresses. It does not knock when I make left turns or when i decelerate. I replaced my right axle about a year and a half ago, but never replaced my left one. A buddy of mine said that it may also be a snapped differential, does any one have any advice for me.

Jack up the frontend of your car and support it on jackstand and check your axles.

If the axles are in good shape then most likely your motor mounts are bad... check the motor mount before buying new one...or repair them if you chose to.

If the differential was damaged, the car probably would not move.

The axle may not be seated properly. Have you pulled either one out recently?
A bad CV joint tends to click when you turn. Thumping MAY be a bad joint, but I'd think clicking would come first.

Check all suspension components (bushings, ball joints, etc...) and wheel bearings. Those things could cause thumping as well... and they could be very dangerous if they fail.

If you're unsure about the axles... replace them. $75 for a remanufactured axle from most autoparts stores is worth your peace of mind. Hell, if it IS an axle, and it breaks while driving, then you'd need a tow... which would likely cost $75 or more!

Get under -- or even jack up one side and take the wheel off to peek behind the rotor/hub.

You will see if there is grease everywhere or not. Then you'll know for sure that a new axle should be planned for. A common sign would be the outer CV clicking when turning, but you shouldn't wait for one.

I've seen an inner joint (driver's mid-shaft) completely done. The ride was very rough. As soon as we got the axle nut off, the shaft fall apart and separated at the inner joint. It almost dropped right on my face, laying down. To be fair... the driver put off the axle for over a year, leading to "WE F^&% TOLD YOU!"

I took the axles out about a month and a half ago when drummersteve and i replaced my clutch but everything was good when we assembled it. About a year ago the joint did pop open so i repacked it and re clamped it with a metal tie. i believe the axle is original when i re built it there was some nasty gooopy grease that just plopped out.

Ghost edit: Ill take a look at my suspension this weekend, 3 out of 4 motor mounts have been DIY solidified with polyurethane.

Ghost edit: about 2 years ago I had a similar issue but it was a slower and harder thump that ended up being a bad CV joint on my passenger side

um

I would jack the car up and go under and grab the axle shafts and try to shake them and if they feel lose or clunk then replace what ever one it is.they are only 50bucks

This is going to sound bad but somehow my joint walked off the intermediate shaft. I had pushed the CV joint against the intermediate shaft and heard a click and now my problem is gone.
