I would say in general, "no". That said you ought to ensure that:
1. your setup/alignment has not drifted out of spec2. the bearings -- if adjustable - are not loose (or tight)
The only wear and tear part is the bearing. If damaged it probably needs factory replacement - or certainly replacement and precision adjustment by someone who doesn't need to ask that question!
Unless it has been abused in some way, i still say "no". I have 30 and 40 year old arms that are un-serviced and work perfectly.
