clunking noise in rear-end of 190E
Has anyone experienced a clunking noise coming from the rear-end in their 190E? When I shift into drive and accelerate, whether I accelerate fast or slow, I get a one time clunking sound. When I accelerate from a stop light I don't get the clunking sound.
Can anyone help me isolate this problem? G |

You might check the center driveshaft support bearing - see if there is any play. Much less involved than having the differential rebuilt. Also check the driveshaft couplers and tranny support bracket.

Check the entire driveshaft - rear flex disk, U-Joint, and especially the front flex disk, which is the most likely culprit.
Most "axle clunks" are the result "driveline slop" caused by a deteriorated front flex disk. They are usually toast (cracks in the rubber) if they have over 60K miles. Duke |

Rear Subframe bushings can cause a clunk if they get bad enough. Visual inspection doesn't always do justice to the problem, but it seems these particular rubber parts lasts for a decent amount of time. I also get a clunk from my ghetto-blasting cut-down-by-previous-owner springs, but this is on single wheel deflection.

Thanks for all the suggestions.
I have already replaced the rear flex disc, thinking it might be the culprit, but it wasn't. I'll take a closer look at the bushings and mounts. Thanks. G |

The rear flex disc is much stiffer and durable than the front one. You'll probably go through several front flex disks before the rear needs to be changed.
