I think the problem is from people "Beefing up" their tie rods. People have been doing this because the are "weak".

Here are my thoughts.. In any system you always have a weak link. If you are smart you make the "weak" link an inexpensive and easy to replace part, like the tie rods. To me the tie rods are sort of like fuses on an electrical system. If they keep blowing then you should know that you have a bigger problem.

Beefing them up will only allow you to break a more expensive and harder to replace part while on the trail.
