This kit is a problem solver at a great price. The factory steering rack bushings aren't available separately from Toyota- you must buy the entire steering rack. The factory steering rack bushings do wear out and get loose over time- especially when using larger tires and/or running off road frequently. This causes the vehicle to wander and have sluggish steering response.
These polyurethane bushing kits will replace your factory steering rack bushings and stabilize the steering rack much better than stock rubber bushings. The bushing color on these kits is black.
