The fact that you asked the question as to whether to DIY or bring it in leads me to think that you will be better off bringing it in.

If you don't hear "clack clack clack" sound during a turn, then chances are the CV joint is still OK.
As mentioned by others, better to use Stock or GKN CV joint.

You can:
- remove the axle and disassemble both CV joints, clean them, dry them
- Then new GKN grease + boots

As a rule, CV joint will easily last some 400K if the boot is not torn open.
There is a VW Jetta driver who religiously replaces the CV Boot every 60K no matter what ("pre-emptive strike"), his CV joint was still good at 400K miles.

CV Boot prevention is the key.
