Rear seal was leaking a little then started doing so a lot where I was putting gear line in before I would go any where or at least checking it and only driving locally. I just changed it over the weekend. Now I have other problem like jerking while stepping on the gas and stalking when stopped for light. Also while in 2w it sounds like a chain rattling, when put in 4 h it quits. If anybody has any ideas. I would like to know so I can try and fix.
