My car rumbles at speeds greater than 60. I just found that when the road turns slightly left it rumbles more. Sounds like CV joint, don't you think? So I've got questions. How do I confirm a bad CV joint? Can I lubricate it? Are you supposed to lubricate them periodically? Can a back yard mechanic change them easily enough?
No you cant grease a cv joint, it is a sealed unit and comes pre greased! when you turn sharp at slow speeds does it sound like rocks rolling around in a coffee ca? then its a cv axle! also check large boots at both end of each axle. if the boot is torn the cv axle is either bad or will need replaced very soon! yes a back yard mech can replace easily but you will need a front end alignment when you are done! hints for replaceing! pop axle out with a pry bar at trasmission., to put back it use old end nut only 1/4 of the way on and hit with a hammer to seat lock ring then check at tranny to make sure it is seate! hope this helps

Sounds like it could be the CV joints, drive the car in reverse for a little and put steering on full lock, the noise will be a crunching sound coming from the front, if so then ist definitely the CV joint(constant velocity) joint, hope this helps
If the wheel is out of alignment so bad that it is noticeable. Then I would be checking the suspension ball joints and the wheel bearings. If the wheel is not held true when running then the cv joint will be binding up and generating the noise.. If you are not savvy to this I suggest you put it on a truck and get it to a workshop before you do more damage .
cv joints are covered with a plastic/rubber boot to keep the road dirt out and lubricating grease in''the inner works of a cv joint are an alloy metal with honeycomb chambers for the joint bearings to fit inside of..do this.. take your left hand and make a fist..then fit the fist into the spread open fingers of the right hand ..rotate both hands together back and forth..your ncv axle turns in much the same way..when dirt gets into the joint due to cover failure..this joint wears out because it has engine torque(twisting) pressure on it while moving..along with grit and dirt grinding away at both the metal and the bearings inside causing lots of slop in the joint..now if the engine torque becomes too strong for the worn out chambers in the joint, they will break..remember they arent steel,,they are alloy..thus rendering the joint unuseable ( slip your left hand inside the right between the fingers to grt the idea.. thats what the cv joint on your car is doing...so replacement is necessary..its not an easy job since most cars front suspension is opened up during this proceedure,,,car is ten years old do you feel that its worth the money? call for rates first...good luck and repost findings thnx
You could have a bad wheel bearing or a bad CV joint. Inspect your CV joint by turning the wheel all the way to the left and inspect the rubber boot for any signs of damage and see if there is any play by grabbing the CV joint and try to move it.
The other way to check is to drive the van slowly in an empty parking lot turning the wheel to one side and then the other. Listen for any abnormal noise and see if you can feel anything lose through you steering wheel.
If there is any signs of damage to the CV joint like oil leaking or movement. Replace the CV joint as soon as possible, and try not to drive the van till you have the CV joint replaced or the wheel bearing. Total CV joint failure will cause you to have the van towed to have it replaced. Try to drive it to the Garage to save you the tow cost.
Thank you for using fixya and be safe.
when a cv joint is going bad on turns whether it's to the right or left you'll hear a clacking noise when it the out joint when is the inner joint must of time you would feel a chimeing on the front end another way to test is put you car on drive and hold the brakes tite and excelerate the engine at the same time if the cv joint is bad your going to feel a loud noise and vibration if you don't feel nothing then you have a transmission problem
