Hello! I have a 1984 200es and it runs perfectly now but as I pushed it back into the garage after about 20 mins of riding, I noticed it makes a slight gear-ish groan from the back final drive area that is very quiet. I never noticed this before but I would just like to know what it is and if there's anything I should do. Also, the past few rides I've noticed a pinkish fluid has been dripping down from somewhere and I would also like to know what that is to. Thanks to all that can help and I can be more specific if need be!
