4000 series hub / upright / spidle options

You can't just remove the caliper and take off the rotor and hub as an assembly?

With only 400 miles on it I was thinking remove the entire spindle from the control arms and ship it all back (spindle, rotor, hat, hub, and caliper) to SAI and have them return it back good as new on their nickel. But I'd like to see a pic of it first.

That works, too!

I just talked to a local shop that works on the first road going 4000 series (built in Las Vegas - unlike the 4700 series that was built else where). The original 4000 series is like a normal car. You remove the caliper and the rotor slips off the hub. My hub has the bolt on the back side and the rotor is pressed on to the hub. I have no idea why it was designed this way, but in my uneducated mind it seems like a step back ward. I will attempt to attatch an image and we can go from there. you can just see the bolts behind the rotor and you have to remove the entire assembly and press it off the up right.

Ahh, I see. And presumably right below the line of sight on the rotor are fastemers going in to the block of aluminum that is bolted to the spindle. And the rotor is press-fitted on to the spindle using a billion pounds of force no doubt. Right?

The rotor and hub assembly is press fit onto the spindle? Again, I am no CSX guru by any means, but I have never heard of such an arrangement. It seems like a solution to a problem that no one has identified yet. Obviously, I am missing something here...is this car still under warranty? Tell them to recommend a shop by you and let them foot the bill if it's under warranty, why mess with it?

There are several 4700 series Cobras that were fully built in Las Vegas from the ground up, like mine. I believe my front end looks different than yours, same caliper, but the rotor comes off like a typical front disc.

I think Ron(computerworks) did a comparison of the earlier front ends vs. the later ones with pictures side by side. Might have been the CAV cars only, I can't recall.

So you would need something akin to a steering wheel puller to get your rotor and hub off. Huh. And then to put it back on what would you use? There's got to be an easier method -- no one would design it that way.

[patrickt]

Is there a castle nut and split pin on the end of the spindle?

mine is 4788 built by HST and when I talked to SAI they said that they currently did NOT have a fix or different parts to replace what I had that would solve the issue in the future. I still just don't get why they ever used this system in the fist place. I called Kirkham and they would have to sell me an entire front suspension (control arms, uprights, spindles, hubs, rotors, calipers and brake lines) for a good price (but still more than I have to spare right now).

That's absolute crap -- and it means my original suggestion of pulling it off the control arms and sending it all back to SAI won't work either. Isn't there a rep from Shelby that rears her head on this forum from time to time? Perhaps she could confirm that there is an inherent and, apparently, "unfixable" design flaw plaguing this series? I would be mad as a hornet....

Bernica, the owner has already spoken with SAI and their answer per the owner is noted above in quotes.

shelbyracer, I'm sorry, but I don't understand how you can say that overall you've been very happy with SAI, when you have this HUGE problem and because it's out of warranty and SAI doesn't have a fix for this possible product defect, you're left trying to make lemonade from lemons. To bad the CA lemon law doesn't apply here, due to the nature of the beast, but personally, I would formally ask SAI to either fix it or replace it with a new roller. Just my humble $0.02.

As Rick said, you can't sell it unless you disclose the problem, and if you disclose the problem, then the value is greatly diminished.

PowerSurge, wouldn't you agree that the statement quoted above, if true, is totally unacceptable behavior by SAI?
