Power steering, aggressive wheel alignment geometry, wider wheels and lower profile tyres have all put radically increased loading on the steering systems of modern cars. Add to that engine bay contaminants such as oil leaks that also help to degrade the performance of steering rack mount bushings. Nolathane steering rack mounts are engineered to outlast and enhance steering precision and feedback.
Soft factory bushings whilst they do a good job of not transmitting engine vibration, they do create vague and unresponsiveness in the vehicles drive train. Under hard acceleration, the engine and transmission rotates, Nolathane engine mount bushings work in conjunction with the OE rubber bushing giving your car better throttle response as well as more crisp and defined gear shifts.
Should have purchased these sooner, factory bushings had failed twice since owning vehicle. After Nolathane bushings were installled, never looked back. Now looking to use Nolathane bushings for control arms on another vehicle.
With regards to the 100 series Land Cruiser, the stiffer Nolothane bushings created issues with the VSC. It seems that the VSC was overly sensitive once the new bushings were put on causing the vehicle skid control to activate during mild turning causing the ABS system to activate needlessly. Prior to installing the bushings this problem did not exist and I am certain it is because the rack needs some amount of movement as it did with the rubber. If you are going to replace steering rack bushings I 'd suggest going with OEM equipment.
Excellent quality, perfect fit, huge improvement over stock rubber bushings and still flexable enough to not make you regret the install everytime you arent drivi g on perfectly smooth roads. What more could you ask for?
