Bearing repack GURUs

[2001LC]

I would replace bearings, next service!

The bearing may just have dust/dirt, or it has pits IDK!. I use micro fiber, to wipe and inspect. Top roller bearing. may be dirt or is it a pit. Bottom roller I'd ask the same.

Race looks a bit scored (black, brown, silver). You can sand in a cross hatch, with fine emery cloth. But replacement is best.
I would have given a failing grade, on this race.

You may have have a little to much grease packed in cavity. I say this because of how much remained on spindle, and signs of heat. Without a small air gap, bearings will retain more heat. But better to much, than not enough grease pack in cavity!

On axle, where axle needle bearing rides. Is very good indicator of condition of needle bearings.

Your spindle took a beating, from loose wheel bearings. Likely long ago, before your time. Use a ~600 grit to polish spindle, it will be fine.

Appreciate the response @2001LC !

I'll see what's the condition of the driver's side next week when I tackle it, I'll try to take some better pics as well. I think the rollers are in very good condition, most of the stuff on them are from lack of cleaning before taking the pic. But the racers are kinda worrying, and I agree that I should be changing by next service. It's gonna be expensive, since I'm also planning to do brakes by then.

A bit baffled about the cause of that, I did use less grease this time, enough to cover everything and some in the cavity, but not as much as last time, when I actually pushed the grease in using the small roller till it squeezed around it.

Can it be that synthetic grease doesn't melt as much as dino, and because of that it lubricates less in these conditions? Like if it doesn't spread around as much and creates chunks of un-used grease? Most of the old grease removed was still like new

I'll dig into my old pics and see if I find any pictures taken on last service. It's been a few years. Just to compare, might be interesting to see the gradual degradation of a bearing during a longer period. (sounds boring, but way more exciting than watching what's on tv these days).

IDK about your grease, how much you added or how clean the whole assembly was.

But when grease covers spindle, to thickness I saw in your picture. Typically, that's from over-packing hub cavity, to point of no air gap. Keep in mind, grease in hub is force outward, while wheel spins. Spindle, which is part of steering knuckle that wheel hub/bearings hangs on, is stationary.

Someone did the math once, based on Timken bearing booklet. They came up with bearing perfectly care for, last about 250K miles. They can last longer, if one cares to use longer. But fact is. Very few are perfectly care for, from mile 1.

I'd say that Koyo and Toyota did a pretty good job designing these bearings, even if it means that we need to keep up with this annoying service every 30k miles.

Every other car I touch that has more than 70-80 k miles has bearing noise. Including other toyotas (corolla, looking at you).

We just did a front hub on a 2018 RR Evoque with 50k miles.. noisy as a train. What were they thinking when they OK'd the design? (or the supplier, for that matter). So it is pretty amazing that I'll be driving with these bearings till next service (315k miles by then), no record anywhere of replacement by previous owner btw.

Both Koyo (Japan) & Timken (made in USA) bearings used in 100 series.

never mind I figured it out

anyone have a link to a good fish scale to use for this job and have for future repacks?

Thank you just purchased.

I would go broke if you ever had an option to “search by 100 series” on your website
