as you've discovered, they installed the wrong tie-rod. if it were me I wouldn't take it back until they have the proper tie-rod in the shop to fix it.
I wouldn't let them grind anything away to try and Band-aid it as that tie rod may end up causing you more issues later on.
They can swap out the ends it could very well be the correct tie rod just wrong ends,or vice versa
The ends won't be bent it will be the end of the tie rod itself that should have been bent
They mentioned something about the synergy instructions not showing you had to remove the factory trackbar bracket before installing the synergy, and that they were going to trim some of the factory bracket off. If something isn't installed properly and is causing the rubbing, I don't want bandaids I want them to take it apart and fix it.
Okay, let's go back to this comment in your OP. As I replied to earlier. There was nothing that should've been cut off of the factory bracket. If there was they have some welding to do. The bolt-on Synergy bracket relies on the factory bracket for a large portion of the strength. Removing any part of it weakens an already vulnerable area.
A side comment: Nice guys or not, your installers have proven themselves to be under-skilled. If I had opened the box on this tie rod I would've known immediately that it was the wrong one. A simple Google search on "JK Synergy Tie Rod" will show tons of pictures to confirm. Still, they went ahead and installed it and sent you out the door with it being wrong and IMO dangerous. The desire to know who the installer is isn't to slam them (although deserving) but rather to inform and allow other people to avoid the same fate. :twocents:
UPDATE:...as of right now, with synergy also being involved in the process, it looks as though part of the issue was a quality control situation at synergy. So far what they have been able to uncover, is that a JK tie-rod made for a dana 60, which does come straight, may have been packaged in the incorrect box, including the incorrect part number and labels. None of this changes the face that some simple test drives by the installer would have remediated the issue before I got my jeep back...but this was the shops first synergy install, they have dealt mainly with AEV and Teraflex. The only point of reference the shop had were part numbers and order numbers to ensure the correct parts were received. Everything they had, pointed to the tie-rod being correct. I am returning the jeep Wednesday, they are setting me up with a free loaner and are keeping the jeep for a while to do a full inspection, installing the correct parts and fixing any paint damage etc that may have been caused by the incorrect tie-rod being installed. Will keep you guys posted with the final results. Thanks for all of your help last night and pictures sent over to help diagnose the issue
I think it is stand up of you not to through the shop under the bus that did the install. I agree, they should have test drove it and not released the jeep to you until it was correct.
But it is not their fault the wrong part was delivered to them.
