Do these CV axles fit the g37x coupe 2009 ? https://www.rockauto.com/en/moreinfo...=2288&jsn=1177 - rear left
https://www.rockauto.com/en/moreinfo...=2288&jsn=1180 - rear right

not sure the difference between the rear wheel drive and all wheel drive axles or if they are interchangeable, Id assume no.

 

For rear axles the AWD and RWD is the same. The two you have listed will work.

 

And are these decent quality or should i spend on something more ?

 

I personally have not used this specific brand, I have only had experience with cardone CV axles which I have not had issues with.
