My old tranny and final drive are out and I discovered that I have a lot of oil build-up in the bell housing. I was told now is the time to replace the rear main seal. I stopped up to a motor builder that I use and he said removing the old rope seal is very difficult. They don't offer any "in the field" work so it looks like its up to me. He did recommend a new seal from BOP engineering. (RMS04 same one as 350 diesel.)
Can anyone shed any light on this or offer any tips/tricks?
