How hard are they to change? In the service manual it says I would have to remove the steering gear from the truck, but on Tony's website he wrote, "increase steering response immediatly noticed after install, only takes a few moments of time to increase the handling of the RAM SRT10," and elsewhere, "Installs in minutes and dramatically improves steering feel." That sounds like the rack doesn't have to come out to replace the bushings, if it only takes a few minutes.:dontknow:
