I have broken both Bilstein shock absorbers on the tag axle, one the upper loop, the other the upper loop and the shaft. I have replaced the four front axle shocks with Koni, and used two of the removed Bilsteins to replace the broken tag axle shocks. What would have caused this? I raise the tag when making a sharp turn. My driveway to road exit from home is at an angle, and I raise the entire suspension to avoid dragging the hitch, could this cause a problem? 2006 Beaver Marquis with 39,000 miles.
