Front end repairs, need advice

[skimann20]

Hello all,
I've reached the point of my 4runner life where things are starting to break and I'm thinking now is a good time to kill a bunch of birds with one stone.

V6 07 4runner with 143K.
-radiator started leaking on the bottom (driver side)
-AC compressor clutch sounds like a machine gun. (just going to replace whole ting (driver side)
-CV joints are ripped open (driver side).
-CAT throwing error on.. you guessed it (driver side).

Is there anything else I should be replacing since the front side of the truck will be open? water pump? pulleys? ect?

looks like you thinking in the right direction, prevention.
Water pump = yes
Pulleys = yes , Bearings are less money, look around on the site.

Accessory belt and a/c desiccant bag since the system will be open. Coolant flush. Power steering fluid flush.
