Random CV joint questions..

Random question:
I have an 04 330xi with 118k miles, all cv joints, boots and bushings were replaced around 90k miles, but I just have a quick question. What can I do to reduce wear on the fragile AWD components of these cars?
Is it true that turning the wheels all the way to one side increase stress in the CV boots? and if so, does that apply only when parked, or should I just try to avoid full lock turns and u turns as much as possible?
I believe i heard or read somewhere that turning the wheels all the way to either side isn't good for some suspension parts.

Thanks in advance.

Absolutely. The mall parking lot crawling and making full steering locks trying to squeeze into a spot is the hardest on those components as it stretches everything. This applys to AWD/4WD vehicles and I have heard the same thing and been so told by others.

I will rather park further away to avoid such situations, or do a 3/4 point turn whatever it takes then making 1 full lock turn.

To extend the life of my front CV boots I spray silicone oil on them every time I have the car in the air.

I avoid wheel lock.

Wrong. The AWD system isn't fragile. There have been very few actual failures. Front axles wear out when pushed to their limits, but an actual failure on front axles, front diff, or TC is very rare.
