Toyota vs GM rust compare.

[LeakySeals]

Comparison of 2 hubs. The top is a 2012 Sienna with 120k. The bottom a 2006 Escalade with 175k. The rotor picture is the 2012 Sienna. No pic of the Escalade rotor because there was nothing wrong so I didn't bother. They drive the same roads every day. In winter because of the terrain a lot of sand and salt is used. The Sienna OEM rotor was very difficult to separate from he hub due to rust. The Escalade OEM rotor was in decent shape and came right off.

How often do the wheels come off of Escalade vs the Sienna? That makes world's of difference in condition underneath and things get wiped down or cleaned up typically.

Doesn't surprise me. Wasn't Toyota the manufacturer that had rusting frames on some of their trucks?

 

[KrisZ]

Well, both look normal to me. I've had bolts and nuts on my old GM car rusted that don't normally rust on other cars.
However, if that hub on the Escalade wasn't touched for several years, then it held up quite well for sure.

Unless they are both the original factory rotors it doesn't say anything definitive.

Even the term OEM doesn't mean they are the GM or Toyota factory installed rotors.

Not saying they are or are not. I don't know. I just know that terms like OEM are often used to get some sort of halo effect. I.E. we are an OEM supplier, so our parts must be good.

That doesn't mean the parts you buy are of the same quality as those supplied to the car makers.

What it does show is how rust can make a job very miserable.

 

[LeakySeals]

Original rotors on both. The Sienna is still original owner. I know the original owner of the Escalade so I know the rotors were never replaced.

 

[SZR48207]

This proves nothing.

Looks like the Toyota hasn't been touched in a while and the Escalade, recently. What the other poster said about being wiped down recently when serviced. It doesn't matter if it's the original owners, but who was serviced recently?

Coated rotors are awesome

Is there anywhere near you that does Krown?

 

[DoubleWasp]

I've seen better rotors off of a salt water boat trailer that never got rinsed. Disgusting.

 

[supton]

That's why I don't bother with coated rotors, they will get looking nasty anyhow and need to be replaced w/in 5 years anyhow. The braking surface gets all chewed up. Just the price of living up here.

I see that you own a 06 Escalade. I agree with the others this doesn't prove anything.

 

[Ifixyawata]

What is the takeaway here? Toyota bad GM good? I've seen both manufacturers have cars rotted in 10 years.

 

[Pelican]

Well it proves that a vehicle costing about 50% more may have better hubs & nuts/bolts

 

[DriveHard]

I live in the rust belt and have owned all kinds of American and foreign cars. In my observations, Nissan by far and away rusts the easiest. The Nissan in my signature is rust free on the exterior, but every gosh darn nut and bolt on the undercarriage has to be broken off, ground off, or chiseled off...just terrible.

 

[Dave9]

Can't really draw a conclusion based on automobile brand, neither would make their own hubs and even if they stick with the same supplier for all, may not come from the same factory.

Do keep in mind that among cost-effective metals, a stronger one may rust easier (until rust is severe which practically never does in a hub unless it chews up the bearing seal and contamination results, or annoyance at seized lug nuts that shear off the lug during removal then usually just the lug itself can be replaced).

 

[MNgopher]

Not sure what any of this is supposed to mean. You state they are the OEM rotors. Does that mean factory original or OEM parts? At the mileages posted for either, I'd wonder about either of them being the originals.

Second, I'm more than willing to bet that the Escalade unit was serviced more recently. Even just looking at the seal behind the hub, with 175,000 miles on it, I'd not be able to read the numbers on the seal so clearly unless it was a more recent replacement or had been substantially just cleaned up. Willing to bet that both may be going on there.

Without the full context, these picture mean nothing to me, other than rust happens in the rust belt. Who knew?

If the OP is trying to say or show that Toyota=bad, and GM=good, there are details not discussed that makes a BIG difference. The biggest factor is this, the vehicles are in driven in salt and sand in winter. Anyone who lives in the northern understand this. What makes all the difference in the world between the two vehicles is this: How fast do the owners rinse off the salt and sand? Do they wash it off as soon as they can? Or do they let the salt stay on the rotors and hubs for a while before they wash the vehicles?

I say this because we own a 2001 SUV, and the rotors and hubs look nothing like those in the photos. Whenever we drove through salt, as soon as I could, I pulled out the hose and thoroughly rinsed off the wheel wells, hubs, rotors, and the underside of the SUV. I think it really helps to keep the rust from forming that fast.

I want to believe that I have witnessed that some bare steel holds up better to salt exposure vs. other, but I cannot prove it. I often wondered if some bare steel components have higher quality alloy mix that makes them stand up better to salt than others.

I knew that my Patriot was made cheap, so shortly after I bought it, I applied a paper thin coat of rust preventive grease to things like the hub, rotor hats, axle end, etc. and I avoided the problems that others on the brand forum complained of.

You guys don't think that some hubs, etc. are more resistant to rust than others??
