Just wanted to be sure before having this done, but the negative battery terminal needs to be disconnected before replacing as to not interfere with the EPAS correct?

 

Yes it does.

 

I forgot to disconnect the battery when I installed the level on my 2014, and luckily I had no complications from it. but when in doubt, just do it, it's never a bad idea.

 

Did mine last week as well but have a little creaking in the right front, I need to check the torque on the suspension but havent has any luck finding the torque values for the suspension yet. Other wise I love the way the truck looks now.

 

also if you can. get a loaded strut comes with a new spring and all

 

I don't understand the concern about disconnecting the battery. I've done mine twice (I didn't like the Bilsteins and changed to BOSS). Neither time did I disconnect the battery. Nothing about it in the instructions.

NO adverse issues.

So what does the front end have to do with the battery?

 

The attached image is from my 2011 factory service manual with torque values for the front suspension

 

This is from the service manual. Any 2011 and later F150 with EPAS should have the battery disconnected before doing any steering or front suspension work. Issues may occur if you don't and if I remember correctly they don't happen right away.

 

^^ not necessary unless replacing steering gear. I guarantee no techs disconnect the battery to change out a tie-rod end!

 

Thanks for the info, but if we read carefully, the manual specifically states replacing/working on the *steering gear* - Only. No mention of the front suspension.

Yes, the EPAS system has a direct connection to the battery (the "E" in EPAS stands for "electric"). But as windmechanic states, almost no tech will ever disconnect the battery... unless absolutely necessary (on anything). I know, I was one. Never experienced any issues.
