It's a manual, so not that.
I have a W123 1982 230E 5 speed manual which has exactly the same problem. I have had practically everything associated with it inspected and replaced. My mechanic now says it is my rear differential gear pinion gears which are worn. I have difficulty finding a new differential gear or find a used one which is ‘tight’ and no free play. How did you solve your problem and do I have other options?My W123 has a manual 5 speed. When pulling away in 1st, if I don't release the clutch gently I get a slight clunk. This also happens when changing to 2nd and to a lesser extent 3rd. There's obviously some play somewhere but I'd like advice where to look first. If I grab the prop shaft, should there be any rotational play at the diff end? What about the gearbox end? I read somewhere it could be engine mounts, but these have been changed recently along with gearbox mount and diff mount. Could this be a sign the clutch needs changing?
The odometer reading is I believe a genuine 210,000 miles. This is because I know the 2 previous owners.What is the mileage of your car?
I convince myself that each thing I did made the clunk go, but I think I was kidding myself I currently have all the rear suspension and subframe off and I'll reassess when back together with new bushes.
From what I've read, I think it's rare to get differential wear unless it's lost oil or has been used for loads of towing.
Hmm. Mine has a little clutch judder when cold. My car has about 120000 miles which is why I don't think it's the diff.
I would like some diff centres if you have them. The part is certainly around 15kg but I am in no hurry, so can find a cheaper way to freight.Hi - PM me if you want a diff centre as I have a few and have come to the conclusion I wont be using them anytime soon. Do you know what ratio the 230E 5 Speed Uses ? Not sure how much to freight from AU to MY tho as they are heavy (probably 15Kgs).
