Loud clicking noise coming from the back or under the car - PeachParts Mercedes-Benz Forum

Hi everyone,

I was driving to work last night and suddenly i started hearing noises like clicking loud from under the car or it was from the rear i am not sure( think it is more like under the car). I had to pull off the road, didnt see anything hanging down or any damage. I tried to drive again, at first there is no noise first two, three seconds then it starts like tak, tak , tak, louder is as you go faster. I am afraid it is gonna be something expensive so please tell me what is the problem? how to fix it by yourself. I suspect something on the differential or some kind of bearing. Funny thing is i canot hear a noise when driving into reverse? hm... hm..

Anyone swap wheels lately? Too long a lug bolt will cause this as it'll contact the e-brake shoes. Or the shoes may have come off the backing plate, these are behind the rotor.

I had a similar noise on the 190E 2.6. New wheel bearings SEEM to solve it, but it's back in a big way. I have NO idea now...

check out the boots around the rear half shafts, at the differential side as well at the wheel side.

I had a dry half shaft on the LHS (euro - passenger) and it made a similar noise ONLY when I turned right - i.e. there was little weight on that side of the car. This MIGHT be the problem on your car as well ....

It turned out that the inner joint of the half shaft was dry. I re-packed the joint (on the car, I just removed the boot by slackening the metal strip securing the boot) and the noise is gone since then .....

it makes sense that the noise disappears when moving backwards because the force on the bearings are different (i.e. there is little wear on the races).

If the boot(s) are shot they are easily replaced - the centre bolt in the rear hub might be problematic to remove, but there is info in the archives on the half shaft and it's removal. I know the US contingent around this site calls the half shaft by a different name, which escapes me now, but someone is sure to come up with the correct term.

good luck
