The next project

[Jinx]

Good morning to everyone. On to the next project.
As I have posted in the past the car has a leaking
Rear cv joint boot.
1 replace cv joint boot. Have repair kit already
2 control arm repair as posted on the Renntech forum


And here is my question. 2003 Boxster
60,200 miles on it. Should I have the
Tiptrinic and differential fluids changed
At this time?
Should I have all this work at the same
Time? Or do it at different times.

Types of fluids should I use?
I am not using my local dealer do the
Work.

Thanks to all
