Axle Bearing Destruction

Hello 3rd Gen Tundra Forum
Own 2014 Platinum Tundra 4wd
Bearing gave out driving down highway load of hay in bed of truck pulled off the highway after I heard a the noise had it towed to my house I pulled the right rear wheel off had major damage the axel hub has been dented is there any chance its worth repairing or do I need to get a entire new rear end?

 

Sorry about your luck. That image gives me vertigo.

 

Do you think a new rear end is the only option?

 

You should be able to get the bearing hub assembly??

 

2014? What caused the problem?

 

Hit a pot hole on highway with load if hay in bed

 

Pic of right rear axle shaft bearing was in bits and pieces in axle housing drained diff and cleaned everything

 

Damn.... couldn't help it

 

Go after whoever maintains the roads in the municipality, If the pot hole is that bad. When was the last time you serviced the diff? I would think it would of had popped the tire and damaged the rim before a bearing.

That much damage has been occurring over a long while.

 

Pot hole just finished that off...agree it looks like its been failing...tire and rim would have been damaged if the pot hole was the culprit by itself.

 

How was the oil level?

better check the other side .

 

This is exactly how I look when I hit a pothole in my 84 c10

 

Lmao yes, me too in my Celica on 17s.. already cracked 2 rims... got them repaired 6 months ago.. lol

 

That ebay auction is a real good deal especially with the free freight. Its also a 2010 which will have the better cross shaft retaining bolt. I paid 1500 and had to pick it up 4 hours away for a 2010 complete axle last year.

 

Who’d have thought all the pay load nazis were correct?! Sorry about your truck.

 

Ha!! I was just thinking the same thing. How many bales were in the truck? 2 wire or 3 wire?

There’s a special place in hell for 3 wire bales.

Honestly even the smaller bales will kick your ass, it just takes a little longer.

 

How do you know when it’s a good time to replace the bearings? I have a 2015 with 100k miles and I haul a lot. I would love to prevent this. How would you know if one is failing?

 

You can jack up each rear tire and try move wheel back and forth and see if there is play...it shouldn’t rock at all but even that might not tell you anything.

There is no way to really know without tearing it all down and by then its wise to replace the bearings anyway.

All depends on use and maintenance. Like anything, there can be situations where parts wear prematurely and through normal use they fail and then there are times when something has been used at or above its max design limits and it finally takes a knee. Not suggesting either way in this case.

For the most part the Toyotas are tough and designed well...I wouldn’t sweat it...make sure you stay on top of routine mnx (diff fluid changes) and don't overload the rear axles. If you are lacking on either, then you could be working toward a impromptu rear end failure.

Again, it just depends.

 

Technically vibration analysis via frequency spectrum is how you get ahead of a failure. I do this frequently at my job...

However for personal use vehicles there is no cost effective vibration analysis method (that I'm aware of).

For heavy use

Check gear oil level frequently. This is of course so easy to do on rear wheel drive Toyotas its dumb not to.
Change gear oil level frequently.
Consider an upgrade on gear oil ( another thread, another day)
When rotating tires or inspecting brakes, check for excessive play.
Plan a preventive replacement.

 

Thanks guys for your input advise hauling alfafa bales they weigh 1500 lbs a piece i had four on trailer one in bed of truck all my diff and transfer oil had recently been changed new bearings on front guess I should of changed the rears 100k miles have a 6 inch procomp lift on it as well

 

Gone through lots of water in past few years?
Anything that would have overloaded the one side vs the others?

 

Definitely. The pot hole was simply the coup de grace. That spline wear didn't happen overnight. I don't see anything left of the bearing, unless that is the inner race fused to the axle. Must have been making a heck of a racket. Failure Analysis: "Lack of lubrication".

Rolling element bearings must be replaced when they fail or wear out. Attempting to anticipate bearing failure and replacing pre-emptively (preventative maintenance) is not a reasonable endeavor for the average vehicle owner. Vibration spectral analysis has probably finally moved beyond laboratory and diagnosis services of 40 years ago, but wide-area screening of the largest plants is still expensive and difficult to justify.

Too many factors are involved in any service application to predict bearing life with any kind of accuracy. Once a bearing failure has begun, life expectancy can be predictable with the right instrumentation.

 

Junkyard rear end. Should be an easy swap though.

 

Thanks all for the good advice. How often would you recommend changing the gear oil when used a lot for hauling? Also out of curiosity what does it cost roughly to replace those bearings. If I took it to toyota to have them do it

 

Holy fuck is a bearing failure seriously surprising
