Grease packing wheel bearings the right way - PeachParts Mercedes-Benz Forum

whunter · #1 11-03-2013, 10:03 PM

Serious common errors are:

* Installing a dry new bearing without first grease packing it.
* Installing a new bearing without replacing the race.
* Packing the bearing and hub SOLID with grease = no air space.
* Over or Under tightening the wheel bearing.

The following Excerpt is a WARNING against excess grease volume....
NOTE:
For best results, ample space is essential in the housing to allow room for excess grease to be thrown from the bearing and for heat dissipation.
It is equally important to retain the grease around the bearing. Normally, the housing should be 1/3 to no more than 1/2 full of grease during bearing assembly.
Too much grease in the housing may cause excess churning of the grease and high temperatures.

Yesterday I loaded a car into my 20' enclosed trailer and headed home from Columbus OH. I was eager to get home and put the cruise on my dodge on about 78 mph. After about ten minutes of this a guy pulled up beside me and gestured toward my trailer. I worked over and pulled to a stop and found a significant amount of smoke coming out around my rr trailer wheel. I felt things and found the hub was hot. I had found my trailer brakes to be inop so I suspected one might be dragging. I pulled the trailer tire onto some wood blocking to allow the wheel to turn freely. I did and it did.

Puzzled I decided to drive to the nearest exit and try to find a repair place. I proceeded along the berm for a couple miles and pulled over again.....the hub did not feel as warm as earlier and no smoke. I decided to proceed cautiously and see what happened. I worked my way from 55 up to 65 without anything getting hot again and came on home.

My question is how the heck can I get the bearing hot enough to make a lot of smoke without damaging the bearing?

Was the tire low?

It was great talking with you.
Good luck at the RV repair center.

Odd that you say this. I recently drove my '81 300SD which had been sidelined for about a month. Immediately I noticed it wanted to pull to the right and had a hard time getting up to speed; very sluggish. After about two miles I noticed smoke from under the hood. Pulled over and found the right front wheel to be pretty hot. Drove cautiously home after a cool down and bought a brake caliper.

Got busy and a couple of weeks went by. So I ran down to the garage, fired it up and decided to take a short drive to make sure I had remembered the correct wheel. Surprisingly it was cold. I have been driving it for a week now and the wheel has not heated up at all.

So I can tell you from experience that the brakes can drag and then they can come back and do OK.

Maybe this is what happened in your case. (But I am not returning the new brake caliper yet.)
