I hesitate to recommend the single servo mod for two reasons. First you need to use a high quality servo as you will no longer have a servo saver. The Hitec robot servo in the link above is the same as the Hitec 79xx series and has proven to be reliable in this application without a saver but I'm sure there are others that will survive as well.
Second reason is it may not be necessary. If you are pulling to one side you may be able to correct it with a good alignment. And by good alignment I mean a total reset and alignment of the entire steering system. Start by flipping the truck over and adjusting the servo trim to center the bellcranks, leave the radio on. Flip the truck back on its wheels and adjust the tie rods to then align the wheels. Pick the truck and put it back down a few times during adjustment to get it right. Once that is done loosen the tiny pain in the butt grub screws on the servo savers. Now adjust the servo trim back to center, move the steering bellcranks back to centered and tighten the grub screws. Make any final adjustments to the trim or tie rods and you should be good to go.
The worst part about the LST steering is the servo savers, they can be weak. But generally a weak servo saver won't favor pulling to one side it just won't center and will pull randomly to either side. The only time a weak saver will favor pulling to one side is with wheel bad alignment. There are also MGT servo savers available for any servo spline that are stronger than LST savers.
