Since I'm getting ready to replace the leaky steering box on my 380sl with 150k miles on it, I'm wondering if I should take the opportunity to replace the steering coupler too, even though there's no indication that it's worn. Looking at the steering box, I was also wondering whether it's possible to remove the pitman arm without removing the exhaust pipe that comes off the left manifold and travels under the arm.
Any advice would be appreciated.
