New windshield - ACC recalibration?

[brk771]

I have found several posts on this topic, but a variety of opinions. I have a Rubicon on 37 KO2’s with an AEV 2 inch lift. I’m scheduled to get my windshield replaced Tuesday by Safelite, and they say recalibration of the ACC system is necessary. I’ve read posts of lifted trucks that failed the recalibration, but I don’t see any any of those posters did to resolve the issue. I understand the need to recalibrate as every windshield is a little bit different, but I’m starting to feel that the risks outweigh the reward. Should I try to convince them not to recalibrate or roll the dice and let them?

thanks.

I understand the need to recalibrate as every windshield is a little bit different,

Not enough to throw things off. There are extremely strict standards.
I was even told by a windshield guy it's not an absolute necessity, but it was the same price and he preferred perfection and wanted to do it. It was the same price either way according to him.

Yes, Jeep says you need to measure from a specific spot on the frame to the ground and if it's over some number, enter the number in the screen during calibration and drive it following the directions.

I had my first one replaced with no calibration and it worked fine for 2 years before I got another broken windshield. The guy was a perfectionist and picky about his work and how things were before he left.

There's no risk to calibration. Lifted trucks simply need someone that knows what the hell they are doing and enter the correct number in the screen when starting the process.

If the truck is out of level as far as compared to factory - say it was drastically leveled, then they may need to ensure the camera, etc. is set correct for the new stance. Again, that takes someone who knows their head from...........
Mine had a bit more rake than it did from the factory due to air bags and spacers in the rear and all of the weight I've added to the front - and it works great.

Okay, good deal. I’ll talk to the installer and make a game time decision based upon their knowledge. Thank you.

I had mine done at the dealership. I put windshield protection film on afterwards, I didn't want to go through that again.

Well Safelite wouldn’t touch it. They said it has to be done at the dealership. I found a local shop that will take care of me instead.

WTF? LOL - THAT safelite shop is clueless. The SMALLER independent shop that did mine knew how and said he done a lot of Jeep windshields and was beyond familiar with the process. He used his tablet to do it.
It doesn't have to be done at a dealership (let alone at all in many cases)
A lot of small shops can do it. Nothing more than a laptop or tablet and access to the MOPAR login to do it. The Jeep walks you through it while doing it. No special shop, no special fancy equipment like targets and so on are needed.
The guy did it right here, well, he had to leave my driveway to get internet connection HAHA, but once he drove a couple of miles, he could log in and he was back in 10 minutes with my truck.

Safelite just replaced mine on the JTR and did the calibration.

I know this is an old thread and I had a front windshield replaced by Safelite and they did the calibration. Last week I had my leaky rear windshield replaced by the dealer who sent their glass guys to my house and in chatting with them about front windshields they say if you don’t disconnect the camera/radar, whatever it is box it will retain the cal and you wont have to recalibrate. If you disconnect the box it will dump its data and need another cal. Not sure how true this is but they do most of the windows for my dealer.

With how simple the recal job sounds, it’s too bad JScan or Tazer don’t include The option in their software.

Even if they could, they won't due to the liability issues.

That makes sense.
