CV Axles

Hey guys. Got an 09 g37x coupe and my mechanic said my CV axles are ripped. The wheel on my car has been shaking whenever I hit speeds of like 65mph and higher. Could this be why? or is there something else that could be causing this? I have had my rims balanced twice already. any help is appreciated

if they are ripped they are probably at least contributing to the problem..the grease in the boots will evacuate until its metal on metal in there ....I'm assuming your'e referring to the front CV axles, but you could have bad bearings up front too if its worse when you turn left or right... check for play in the bearings....changing the bearings and the front CV axle together is a good idea as taking the bearing out makes changing the CV axle easier anyways, but if the bearings are good just change the axles

FWIW, I jsut changed my passenger side front axle and my symptoms were similar to what you described and I noticed it was worse on days it rained... when i got to it both boots were torn and all the suspension components were heavly coated in grease...I couldnt even see any of the silver of the aluminum LCA if you can peek under there with the wheel turned and compare to the other side of the car you'll see a difference right away...one side every thing is silver and the other side coated in black grease

also I've changed the front bearings after bad pothole filled winters on this car 5 times....one was due to the replacement part failing so don't rule that out too... my only solution was to move somewhere with less potholes...

So did the axle change help the symptoms at all? or are u saying they went away when u moved somewhere without potholes?

lol sorry, yeah the axle change made the symptom go away and was recent problem...mine was so bad it came out in two pieces...

the moving away part was related to having to repeatedly change front bearings after almost every winter...

Once they tear and lubricant dries out and let's crap get in you'll have to rebuild the axle boot and repack with grease or replace depending on amount of damage
