Hello all, first time Mazda owner here, bought my 2008 Mazda3 Hatch last week amd so far i love it. She has 160,000mi on her. But sadly ive found out she needs new CV axles. I plan on replacing them myself. Got them off Rockauto(cheapest i could find, money is super tight and this is my only ride to work) and the should be here by the end of the week, is there anything i should be prepared for or watch for while replacing these?
