Hi all. Just joined.
I have a 1980 300TD W123 and the other day driving in the country there was a noise coming from the left hand rear wheel; sort of under the car area.
The noise started after a half hour of driving at over 70mph and got louder. After stopping it seemed to go away until the same pattern was repeated. It seems to be louder when power is applied, but only after reaching the high speed. The noise then remains until I have stopped.
Theres no noise just driving around town at normal speeds. It only starts at those high speeds and after some time.
Something sounds like its whacking in there somewhere with the wheels turning. I'm guessing CV joint but suspect something else moving latterally, in and out?? The boots are old but not split yet.
Any advice would be appreciated.
