I installed a set of Moog inner tie rod bushings today, part K6677. At 108,000 miles, my originals were cracked, and they allowed all sorts of movement. The Moogs are a two-piece design, so you press the old ones out (I used two sockets and a vise), push one new bushing in from each side, and slide a metal sleeve in the middle. The bushings themselves are made by RAMCOA, who I hadn't heard of before, but the material's sort of like polyurethane, and they seem to be well made. The whole kit was $16.99 from O'Reilly's, and includes bolts, washers, the large plate that goes in front of the tie rods, and the lock plate. The tie rods are much tighter now, and the steering feels tighter. There's almost no slop in the system now, but I do also have a steering rack clamp and brace. Overall, for the short amount of time it took to install them and the improvement it's made, I definitely recommend them.
