Rear axle blanket/diaper required on all TF starting at Charlotte? (14 Viewers)
- Thread starter LoPony
- Start date
I was there Saturday and sitting around 2 hours because that sticky fluid got all over the track sucked. I’m glad they are making them add protection to prevent/mitigate that. I’m sure Tony Sch didn’t want to destroy the track and im Not upset with RWR in any way, but adding parts to prevent this (reduce the chances) is welcomed.

Based on nothing, but my observation is this.
No Chrisman failures before, then two on the same car in two runs.
I would be looking very closely at the chassis. Something weak? Cracked? Flexing under load?
The fabricator in me tells me that back to back failures of a part that has never failed before happening on one car just might be the car.

Was it Millican or who that had the other failure? I thought blankets were mandatory after that? Alan brings up a good point. Something else could very well be an issue though if both rears were built at the same time with parts that may have been compromised that could also be something. Sure hope they can actually point to something that contributed to the failures after all this. Talk about frustrating....and expensive!

absolutely logical train of thought. clay's car had a pinion snout (chrisman) break about 3 summers ago,
but it was not a new unit, it had many runs on it. i think at sonoma?
i believe tony is currently driving the chassis clay had last year. not sure status of clay's current chassis

something may be out of alignment. chassis is where I'd start

So Doug Kalitta's failure last year was a Strange?

Here is a picture of Doug Kalitta’s car at Pomona 2026, equipped with a strange. Both his car and Langdon’s car have the strange unit.

All the oildowns from rear end failures in the past couple years have been from Strange rears. Schumacher’s two at Pomona were the first Chrisman failures in a long time.

There's already blankets around the Strange rear-ends, however these are not diapers. They are to keep you from getting slapped upside the head with a piece of ring gear...although some of you could use it...but that's another story.
I think it would be a push to get a blanket developed by Charlotte for a Chrisman rear-end. I think figuring out what happened first would be a good start.
Meanwhile, for those of you who clammer for the old days, you can reminisce by watching the oil sweeping truck drag up and down the track for two-hours.

I remember those days as a kid, they were brutal. And they happened a LOT.
How likely would it be that it could have been poor quality steel, perhaps, when these two rear ends were made, assuming they were made at the same time? Is there a stamp number or anything that tells the mfg date? Assuming that each break were almost the same - were they?
Given a first for this brand, maybe a crazy most unfortunate coincidence?
Also how is chassis flex measured? Slo-mo film? Kinda embarrassed to ask but are things like x-ray'd for examination? (for micro-fracturing)

The rear housing is aluminum, and I'm told the Sunday rear was brand new.
The rear would have to be properly aligned for the coupler to be installed, but if something is flexing under full load, it could certainly overstress the pinion area. That's my thought.
And again, I am diagnosing from 1000 miles away, just tossing the idea out.

Then we would be cleaning up way more often.
