Vibration coming from front axle when coming to a stop it gets worse, brakes are good , maybe cv joint?

Roar can often be associated with failing wheel bearings, but they usually don't cause severe vibration, maybe a little bit when turning. Vibration in the drive train is most often associated with struts and/or CV shafts/joints going bad. If you are sure the struts and strut mounts are good, then I'd have the CV joints looked at.

The question is the source of the vibration. Emissions issues may cause engine misfires and vibration. However, new ball joints suggests you experienced vibration in the steering wheel. Worn ball joints CAN cause this, but since replacement did not fix it, the next source is a worn inner CV joint on a front axle. This CV has to smoothly allow for suspension movement, and the concurrent in-out axle movement in the CV. What happens is the CV binds and generates wheel vibration, which can be severe. Have the garage check for wear in the inner CV carriers. Replace the axle if necessary.

worn Struts can add to vibration

Sounds like maybe a busted motor mount or transmission mount, or a worn out cv drive axle.Look under the front of the car at the drive axles there is 4 rubber boots 2 on each axle inner boot and outer boot.See if one or more of the boots is torn or split.

Most likely one of the cv joints is coming apart, in which case the axle assembly should be replaced.

Sounds like you may have a bad CV joint. The CV joint allows power to transfer to the wheels while still allowing articulation of axle while in rotation. You say the sound and/or vibration follows the tire rotation speed, this is a good clue to allow the elimination of components it couldn't be.

Things it could be;
Generally, the output shaft of the transaxle, inner CV joint, axle shaft, outer CV joint, stub axle (this is usually part of the outer CV joint and is splined), the hub and bearing, brake rotor, wheel, and tire.

A visual inspection of the axle and CV joints, and to check them for play may show the problem location. You say the sound stops while execlerating, this means that the power from the engine is removing the ability for the loose part to "rattle" around. Most of the time this is a CV joint.

If you want to inspect the CV joints yourself, as a general rule there should be no rotational play in the axle shaft by hand. By this I mean if you grab the axle shaft and try to spin it one way and then the other you should feel no noticable play. The CV boots (the rubber covering around the joint to keep dirt and moisture out and grease in) should be clean and dry. Check them for splits, cracks, or just generally grease seepage.

The outer joint (the one just behind the wheel itself) is more likely to have this kind of problem due to the fact that it articulates much more than the inner one, in order to allow you to turn the wheel during steering and still apply engine power to the wheel at the same time.

Hi:
You should have your right drive axle inspected, especially the rubber CV joint boot. if it is split open , it is the most likely cause of the grease you found. Unfortunately, the damage to it is already done, and that is what the vibrations are most likely caused by a worn out CV joint. To fix or repair it, you need to replace the cv joint or drive axle assembly

It is a front-wheel-drive car, right? It sounds like the CV joints are starting to go bad. CV joints connect the driveshafts of the engine to the front axles: they are basically very fancy versions of traditional 'U-joints' found on rear-drive cars. They are protected by a big rubber boot, which eventually gets ripped or whatever, then dirt gets in, which starts to grind away at the joint. It's probably $500 to replace the CV joints, maybe more on a Volvo. The good thing is, the sound will get much, MUCH worse before it actually falls apart and leaves you stranded. So you have some time before you HAVE to get it repaired.

Good Luck!

If the wheel is in balance and there is no other signs of what is causing the vibration than yes that cv joint should be chk. Is the strut ok? might want to chk. that too.

have your cv joints and wheel barings checked. I would suspect an inner cv joint. Let me know [email protected]
