Bearing service

[BigTexRex]

I've used Red Line grease with great success. It will take heavy loads and high heat.

I pulled the information from here: https://www.etrailer.com/Trailer-Axl...45I-EZ-89.html , but haven't verified on the trailer. I plan to go to storage and check one of the seals this weekend. Then I will order new seals. I will be repacking in the next few weeks.

I bought Allstar ALL78241 Timken Brand Premium Red Type Wheel Bearing Grease, and timken 473336 Seals, from amazon for my 22RBPR.

I think my axles are 3500LB.

If everything fits let us know.

I pulled the hub, but didn't look at the bearings. Below is the current seal on the hub. I ordered 4 to repack. I can check the bearings when I clean them.

I brought the TT home today to start the repack. I pulled both hubs on the right side and found that the bearings have an area of discoloration on all 4 bearings (inner and outer). Unfortunately, I only have one backup set of bearings. I thought I might run into some that needed to get replaced, but not all. I replaced the races and bearings on one wheel. I ordered 4 more sets for inner/outer bearings. I hope they arrive Sunday and the HOA doesn't complain about the TT in the driveway. Maybe I should repack every year. Here are the Timken (made in USA) bearing sets.

If discoloration is blue they were too tight &/or not enough grease, that's the only discoloration I've ever seen, unless on a boat trailer & show rust.

This is the first bearing service. I bought the TT about 2.5 years ago. Many have mentioned that factory doesn't put enough grease on the bearings. The nut was slightly loose on both of them, so I believe it was set correctly. I packed the one set I have with a bearing packer. Here are some pictures of the discoloration on the bearings. First picture is outer and second is inner. It is just on one area of the bearing.

Hopefully you changed those out as they both look like there has been debris on the inner race.

I ordered new bearings from Amazon. I plan to change them on Sunday. I could only find Chinese bearings at my local trailer shop.

What I "think" you are looking at is the I.D. of the inner race to spindle fit. There will usually be some discoloration there. It has a very slight clearance fit. Grease can find its way in there and stain the race. You should be concerned if you see some "color" on the rollers and their corresponding fits on the inner and outer races. There are other signs of distress including spalling, etching, and pitting.

I didn't see any discoloration on the rollers or races.

If the rollers are shiney and the races show no more than a light grey "track" where the rollers are running, I would say it's good.
From memory there is a good write-up on the Dexter website about bearing maintenance.
It's simple, but it's not.
40 years in turbo machinery and I messed up regularly. But a lot less than some others.

From what little I can see in the pics, those appear to be stained from the grease. Can't tell about the rollers, they appear to be reusable, as I said, from what I can tell.

[mfifield01]

I'll probably just replace with Timken bearing/races. One has been replaced, I just need to wait until Sunday for the other three.

I think I said this way earlier on this thread. While I can agree on some grease staining. The blue/discoloration on the Chinese bearings I pulled out of ours was from too little grease and overheating. It also included a chipped cone roller as well.That was after only about a couple thousand miles. The replacement Timken after about 15-17,000 miles had no staining or blued rollers. There was grease staining on a couple spindles which surprised me. That easily cleaned off with 1500 wet and dry paper. I now have a full 6K suspension and will be looking at least one assembly this spring but not a full disassembly unless I find a problem since we only put about 2600 miles on the RV last year.

If we ever purchase another towable RV, new or used, one of my first projects will be to look at the bearings (and brakes). It has been well documented through various forums that many owners have initial bearing problems.

I took some 1000 wet/dry paper to the old bearing. It came right off. I believe it's just grease stain as the color looks to be tan. It was on the bottom of the spindles as well. I don't really like the idea of sanding the spindle. I have around 11,000 miles on trailer.

I will probably take the trailer back to storage today. The parts won't arrive until tomorrow and the high is 36. Today the high is 59. So much for a one day project.

You will never take enough metal off that spindle to hurt anything with 1000 and up wet and dry paper. We used 220 to clean large dia.(10, 12 and 14 inch) generator bearings. We also used 600 grit to clean nuclear sub liquid sodium coolant pump rotors

My preference would be to try some Scotchbrite first.
I've cleaned up some pretty big boogers on spindles, on the seal fit, with a file and 800. Usually weld buckshot from the spindle being welded on.
Hit that spindle with 800 or better like you are shining your shoes and won't hurt the fit, if you quit in time! LOL That bearing to spindle clearance isn't much. If you get carried away you get the race spinning. Not good.
