I'm sorry....but this doesn't sound correct?The service writer said that he was unable to get the steel steering box. When he tried the system bounced it back. I trust his word on this. Seems rev b screwed me.
The Service writer has to put in the order for the steel steering box, after performing an inspection on your vehicle. If they believe you have the issue, they can order it. Also the TSB indicates that if the owner says mentions the detailed symptoms the dealership is supposed to make the repair. There has been some issue with dealerships not making the repair if your jeep is modded though.
FCA is being very restrictive when it comes to the box and the bolt(s) that comes with it. And it may take a while, depending on where you are located. I'm in Houston and it took almost a month for the parts to come in. Also there may be a list of people before you, if the dealership is indeed performing this repair.
So, I don't believe your service writer is being honest...
I highly recommend you contact @JeepCares and inform them of what was told to you. I reached out to them and they were extremely helpful with getting the parts to me quicker.
