In my W114/5 days, trouble with the center bearing and bushing was usually a thumping on acceleration. I had a couple replaced and I recall it being in the $100-200 range.
If it is the noise described, it is more likely the bearing and it is replaceable. If it a thumping, then it is the bearing support mount. Also replaceable.
