I need new rear axles--are you kidding!?

seems like flange runout is only part of the story. Seems like one could have the flange be bent w.r.t. the axleshaft with the axleshaft still straight (although admittedly somewhat unlikely.) And not obvious how flange runout would indicate a bent housing.

Well, I need to make a decision........
Here's what I know:
*Most 100's go 200K+ miles before needing rear seals and bearings.
*Mine went at 105K so I must conclude that I had a problem WAY BACK THEN.
*The were fixed and they went again 55K later. This tells me that I developed the problem shortly before the original failure at 105K because I didn't get another 105K...I only got 55K.
*OEM axles that can get messed up again cost $1050. There are NO after market chromoly's.
Decision 1: Have them put it back together once again for the $900. Then prepare to do it again in another 50K (4-years) and hopefully by then I can get better after market axles.
Decision 2: Buy new OEM axles and have a like new rear setup...$2000. Hope I don't bend the damn things again.
WHAT WOULD YOU DO?

Because those never break anything.

I would get a proper diagnoses
What more should I ask them to check out? Remove the axles and then re-measure? How do you check for axle housing alignment?
No way...my '97 LX is for sale. Want it gone!

Spoke to my buddy at Toyota...
*He highly doubts the axle housing is bent...never seen it on a 100. He also said that it would show up on an alignment. I just had one and the rear toe was +0.16 on one side and -0.05 on the other...therefore no bent housing.
*And yes they did measure at the runout at the flange. From what they've seen on the Tacoma and 4Runner this flange measurement also reveasl the shaft itself is bent as well. That said...I'm the 1st 100 he's seen with bad runout at the flanges.
I told him to R&R the stuff...no new axles. I'll prepare for the next time and will watch for chromoly's to come out. Why put in $1050 axles that I can bend again...like Spressoman. He and I are gettin' shafted!

I would still like to know of the area where the bearing / seal goes is bent or just the flange on the outside of where it mounts to the housing.
Chromoly axles will take more shock load, but that does not mean they will not bend.

On the way there
They are completely different, might possibly share the same pinion flange, but that's all I can think of.
The shafts themselves are larger in diameter, 32 splines at the diff instead of 30.
They are semifloaters, with a really goofy axle oil seal arrangement, and a sealed bearing that requires a press to service it at all. Not really a friendly axle to deal with in my opinion, at least not in the driveway.
Regarding the housing, Toyota axle housings can and do get bent. It can be pretty subtle. Maybe the 100 is magic in this regard, but all the others get bent axle housings, and bent shafts.
It sounds like Shotz' axle is bent at the flange from a pinch. Not too surprising considering the amount of ornamental rock crawling it's been subjected to.
Why not buy a complete axle at a wrecking yard? If you look for one in a front end collision, the rear axle should still be great. Then it's just a matter of swapping in your geared 3rd, change the oil seals and install as a complete unit. As a side benefit, you get a whole bunch of spares.

Now that's funny Andy.
John doesn't need spares. Robbie will be there at all times to fix his junk.

Thanks Andy
Was thinking the same thing. Although 100's in yards are more rare than hen's teeth it seems...
It's going to be a big bend in an axle to do a seal in, which is mounted next to a bearing, or the bearing is flogged out.
As mentioned previously, flange runout may have NOTHING to do with the axle runout or the bearing and seal surfaces. If you flange is bent you may experience radial imbalance of your wheel.
The axle hasn't been measured for runout correctly so bearing wear is a possibility etc. etc. Sounds sus to me, Toyota know you have the cash John!
They have to remove the axles to replace bearings/seals, get them measured correctly and find out if they are bent.
