With regard to the axle shafts....
I'd suggest only doing the outer .. "Half Shafts" initially.
Basically from "Green Cup" outward on each side.
This is usually the culprit with clicking etc on tight turns...
...and also when TOD kicks in...as this loads them up and
cause binding/clicks not always noticeable when TOD is
not in "action"
When doing this, check condition of inside of "green cups"
for excessive wear and fit of new races.
If OK.. you should be good..if sloppy... entire new axles may be needed.
What replacement axles are you using...some are good..
...some NOT so much!
The Sur Trac replacement axles are very good if not used for aggressive
off roading.
The race/balls and tolerances are up to OEM spec.
