Energy Suspension Sway Bar Bushings/Sway Bar Link Problems?

At 60,000 miles I replaced the stock sway bar bushings with ones made by Energy Suspension. At 70,000 I broke my right sway bar link. I then replaced both the left and the right links with Raybestos Pro Grade links, saving the stock link from the left side for emergencies. At 74,000 I broke the left link and reinstalled the stock link. Is there a "link" between the two? Has anybody else had a similar experience? 1998 Tacoma

 

Do you wheel your truck at all? The new bushings are going to be harder than the stock rubber so, if you wheel it, there will be more stress on the sway bar and end links when you flex your front suspension. If you've got a lift, that changes the geometry for the sway bar and can add stress as well.
