I just had the right front wheel bearing on the 87 190e fail ..... while driving. Not pretty, quite scary but luckily OK. The car has about 230k miles.

I was on the highway, just came off a series of twisty mountain roads and noticed a bit of front disk squeal all of a sudden. Rock or something I thought and continued. Went from one highway to another and all of a sudden a clunk and a lot more squeal and a slight list to the right. Stopped way off to the right side of the road, got out and checked around and didn't see anything obvious but drove home real slowly.

I took the right front wheel off and shook the disk/hub. It wobbled. I took the dust cap off and it was obvious the bearing failed. I took the hub off and found the outer bearing attached to the axel!

I had to replace the hub/axel and the bearings came with it (used). Car is back on the road and is fine once again.

I know I adjusted the bearings about 15k miles ago. I should have removed them and cleaned them, repacked them and then adjusted them.

Hope this sends a careful suggestion/reminded to everyone with higher mileage cars. Remove the bearings and clean them.
