Wheel Bearing Replacement Semi Trailer

Don't, I repeat, DON'T scrimp on bearings. While tempting in these financially troubled times, that Chinese crap will leave you stranded, and most of the stuff today is imported. USA, USA,,,if you can find them, AND afford them. You get what you pay for,,,

 

9/16 wrench and looks of that one a hammer too.

 

Does he know to grease them? Often?

 

Man those slack adjusters are drier than a popcorn fart.

 

While I was really strong with James opinion mine has changed a bit. Metal flaking off and damaging the differential is a good point but I thank his trailer is safe. I miss things in posts as well.
There are military specs on many things like this. The spec on bearings is probably like oil. Delo, Rotella, Mobile etc. As long as it meets that spec it can all be mixed up and life is good. That is what the military spec means.
About 15 or 20 years ago I came into work. It was day light but the sun was not up. There was a high dollar horse trailer parked off to one side of the driveway. It had a bare spindle on one axle. It was purpleish blue. I thank that is about 6 or 700 degrees. I knew who it belonged to and they were headed to the quarter horse congress show. This trailer was less than a year old. It had multiple different brands of bearings and races in the one hub. Told the owner they are all supposed to be interchangeable but I don't like that. Wish they were all Timkin or Bower. All the same brand and USA companies. He said change them all. I called my favorite supplier and told them what I wanted. They ordered them and sent them to me. All the same brand in the same colored boxes. Some were made in USA, China and several other countries.
Still a bit speechless about that deal and feel lucky just to find anything these days.

 

Those are manual adjust slacks. I'm not certain of your terrain and work. But physically adjusting them once a week is a must.

 

I mixed new brands. I'm not a fan, but never seen a failure. I dont even inspect a bearing till after I inspect a race. If the race is worn, it gets a bearing.

Now if your really a stickler, Timken used to offer "matched set". Race and bearing in closer tolerance than standard oem tolerance.

Not sure if they still do.
