I didn't see any thing wrong I checked mounts I tried to feel if the vibration was coming from the rack itself watched the tires and hub assembly as best I could, watched the axles I saw no issues at all.... I'm at such a loss. It's so aggravating


You can force-flash through WiTech, but it being "up to date" would indicate that whatever the latest code is has already been flashed. This is the case for both WiTech 1 and WiTech 2.

There will be a code associated with the update referenced in the TSB, it is very easy to cross-reference that to whatever version is listed as available and flashed on the module.

So what exactly do you mean?

 

[OVERKILL]

The EPS would be a module in the "tree" that gets brought up in WiTech. In that tree, you can click on each individual module, even if they don't show an update available (lightning icon) and it will give you both the latest available software for that module and what you are presently running. This is how I flashed the SRT8 TCM programming on my wife's old Charger

Subsequently, if the update was available for your car, it would show up as the latest version under the module, and could then be flashed. If the latest version and your version match, then you already have the revised EPS code.

Make sense?

Some what. I have zero experience with wi tech but basically wouldn't they have known if it was able to updated or not? It should have shown up with something saying it was at the current software level or what have you?

Depending on your interest in pursuing this, you can rent the Drewtech RAP box and have Drewtech do a calibration check on the EPS module. If the update is available, Drewtech can do the update for you for the $125 fee.

Depends entirely on how well the tech knows the software. If the lightning bolt doesn't show up, many may simply think that means that module is "up-to-date". However, that just means there isn't a pending important flash for it, it does not mean that if they were to click on the module, that it would not show an optional update (perhaps pertaining to a TSB) available for it.

Now of course, this can go wrong too. Just because there's a newer software version listed, it doesn't mean that the update is applicable to your vehicle. That's why it is imperative to always read the errata that's listed with the update. For example, there was the shifter update that showed in the available updates for my Charger. However my Charger had the Mercedes NAG1, not the 8spd, so that update, whilst valid for the module, was not valid for my car.

Ok that makes sense. I'll make sure and speak to them and make sure it's not available. Two dealers told me it wasn't but I have little faith in them anymore. It would wonderful if that's all it was !! But who knows I'm dropping it off tonight so maybe they'll figure something out .

 

[ram_man]

Well a little update they said they re checked and the module can't not be reflashed to a newer update. They road forced the tires ..... still have the vibration. They honestly have no idea as of yet either. They are thinking it is engine/ transmission related. But can't pin point. I feel for them because I looked for a couple hours the last time and couldn't find anything either. They do feel it though so at least I'm not getting the "it's normal" line. They seem at this point like they're trying to figure it out honestly.

 

[OVERKILL]

I would have liked to have seen the WiTech screen showing the module. For some modules, they show absolutely no flashes available, which may be the case here, but if it is, I would have liked to have seen it.

Does your girl friend's car do the same thing? Maybe switch wheels between cars and see if your car still vibrates with her wheels on it. If vibration goes away just keep those wheels on your car. She probably won't notice the slight vibration in her car. If she says something then just switch them back.

Agreed. I think the OP should utilize the Drewtech RAP service in this case.

It's not really slight its more moderate than slight. We already did that with no change anyway.

 

[OVERKILL]

These are of WiTech 1, but 2 looks similar, albeit it is web based.


This is the vehicle "tree", you can see there is a symptom-based flash update for the Electronic Shift Module:


The update details, showing both the current code for the module as well as the update:


This is a module that is already current, you can see the two numbers match:


And this is a module with no available software (in this case, the EPS Module):

The dealer reached out to Chrysler and Chrysler told them my after market exhaust is a problem. I removed the muffler and put in an aftermarket muffler.....chrysler says they can't test it further until that's done ..... I hate dealers

They may be correct. When the LX series first came out my good friend bought a Magnum R/T. While modding it up he installed an aftermarket exhaust. The resonance was incredible! But the kicker was the weird vibe it introduced. No one could figure it out until he replaced it all with a Magnum SRT8 exhaust. Still had ridiculous drone at specific rpms but was MUCH quieter and no vibe.

For a truck you must be careful because that huge bed is an excellent resonation chamber...

99% of the time, when we find aftermarket items on a car, it is the aftermarket part causing the issue. It is very real.

 

[OVERKILL]

Given the car's Italian origins, I wonder if the OP's "modification" is a Cannone di flatulenza?

Do you still have the original muffler to swap back on? What brand muffler is the aftermarket one? The muffler maybe the issue at this point.

 

[sleddriver]

Your tires are not round.

You can balance a square, a triangle, even a rectangle on a machine but it won't roll smoothly on the ground. Only a nice round circle will.

At that speed, it's your tires unless it's a rim.

You either need new/better tires or to seek out a shop that will lathe your rubber tires round.

 

[ram_man]

If it was the tires swapping wheels and tires would have helped solve the issue I swapped wheels and tires with no change.
The muffler is not the issue. They admitted to that later in the day when they told me they had another dealership Tech they knew have this same issue and it was bone stock they replaced everything in the front end and it didn't ever fix it.......... they told me specifically to trade it in....... sigh
