Hey samstone. I just just had the cv axles done in my car too. A few recommendations. The cv axles themselves AND the labor (my shop charged me 1 hour labor! mechanic said it was one of the easiest cv jobs he'd ever done) shouldn't cost you more than $150. I think I paid 80 bucks total for my cv axles, just make sure you bring the old ones back for the core refund. I probably could have done the job myself, but for 1 hour labor, I'd highly recommend just having a shop do it If you have a mechanic you can trust, this ones a no brainer when compared with the headache of doing it yourself. I usually recommend to people to do the work themselves and learn about you car etc, but this job, though reletively easy, is a huge pain in the a$$.
Also, make sure you actually need new cv joints. Are they clicking loud esp around corners? If you just want to replace the cv boots due to cracking, you can get a boot kit for cheap and just replace them.
And, I'd recommend not getting your cv axles from carquest. Mine were installed and a month later the boots had split and cracked again.
Best of luck!
