That's 170 & probably 100 on the diagram. Never done it but probably not too bad to do. See what others post.

I've never done this job. I thought 170 was the RHS seal??? Big difference in seal size - yes

Just checked. 170 is the output shaft seal for the RHS - The reason they use such large differences in output shaft size is to offset torque steer.
