I recently changed my front brakes and rotors. While they were off I noticed the cv boot was off of the axle on one end and the grease was spitting out. It's starting to get a kind of "whining" noise which I'm guessing is starting to come from a lack of grease. I just want to replace the whole axle instead of the boot. They have OEM axles on ecs for around $400 and some other brands for around $100. Has anyone every tried a "cheap" axle? And how do I know if my car has a standard or tripod style cv joint? It's a 2001 vw gti with the 1.8t (AWW) engine.
