I've seen those ridges and I think they are caused by acid in the grease and lack of distributing the oil in the grease. Not from the weight on them. For those who don't know, grease does not lubricate the bearings. It's the oil that the grease releases when it gets hot the does the lubrication.

I donít disagree with you. That could be the reason I just always associated it with the unit sitting in one place for extended time periods. You have an opinion that I can accept.

As for the grease makeup.

You again are very correct. The remark I made about mixing greases was based on your description of grease. The compound used to hold the oil varies between manufacturers and it is not uncommon for different greases when mixed have less than desirable results.

It sounds like you have experience similar to mine.

In the aviation industry involving large aircraft (15 passenger jets and up) when an aircraft is stored for prolong periods of time the manufacturers maintenance programs has a section for this. This section requires wheel rotation in specifies intervals. There are many more requirements as well. If you wish to find out how expensive it is to let your 8 million dollar jet sit around without use I have one for sale LOL

My acid remark was just a guess, but the only logical one I could come up with. It could very well be settled metal particles. I doubt that it is from the weight sitting on a roller or ball; they're just too hard.

I've seen that dark build up or ridges in gear boxes or transaxles from just sitting with no weight on the bearings.

I always remove all the grease, especially if putting in new. It removes all the debris and ya never know what changes have been made to a grease or oil formula. I blow them dry, but never spin them up with air. That's a sure way to ruin a bearing.

Aircrafts are kinda like RVs; everything costs more. The thing is, with a plane, you can't pull over and say "time out".

Hi

I donít know how long you have been working on this type of equipment but when I was young 50 years ago bearings were hard. I have had pieces removed from the backs of my hands because they were so hard that they would chip when driving the race out of the hub. The bearings of today are so soft that the races donít chip when you drive them out with a punch they bend and if you miss putting a new one in you will put a dent in that nice shiny surface. I havenít had one chip in years.

I base my opinion on what I see. When I remove the inner and outer cones from trailer hub and find 2 of those ridges in the race that are not dark and only 2 side by side and the rest of the race is nice and shiny I find it unlikely that it would be corrosion as the rest of the race doesnít have any irregularities or discoloration.

Back in the 80ís when the economy was so bad the new car dealers were having tremendous problems with this. The new cars had set idle for long periods of time and the front wheel bearings were failing in the first 3,000 miles. They came up with several reasons. The ride on the train bringing them in, the storage in parking lots for 12 to 18 months but not corrosion.

At any rate both corrosion and my idea equates to a yearly inspection of the trailer wheel bearings if the trailer sits for several months at a time. This cleaning and repacking with grease will correct the problem regardless of the cause.

Per the instructions, I would pump marine grease in till the spring loaded inner disk would move ~1/8th inch away from the hub. If grease ever comes out of a seal, you are putting too much in or the seal went bad.
I never said that. But proper procedure must be taken to prevent seal damage and bearings will last as long as no contamination is introduced to the bearings and filling the hubs using the EZ lube method is the best way to keep hubs filled and clean.
