Usually is the teeth part that goes kaput. I think material too soft and not reliable. New ones made in Japan around 1.8K, Thailand 750-900, China around 400. So, if the teeth goes kaput, it's impossible to repair that section alone unless that part is sold separately. SC will quote you around 6K with workmanship included. Outside workmanship around RM300. But would be the steering rack repair pricing?

The key is not hitting the end of the turn like you said. But, still these things should last a much longer time. It has became a meme on the internet instead.

The repair on the bushing seems to be a lot on Nissan/Toyota cars in Indonesia. Not sure if the Honda steering rack has the similar plastic type of bushing?
