Suspension on 2014 RLX

Hey guys,

I've got a 2014 RLX I've owned for a few years and for starters, love the car. Absolutely love it.

I'm pretty sure I've got a CV joint going out and want to replace the front axles. Anyone here ever done this? I was also considering just doing coilovers on all wheels since the suspension is starting to have issues, cause current cost to import OEM for the whole deal is around 4k and I'd rather just buy the parts to mod the car at this point.

Thoughts, advice would be appreciated.
