Hey guys, for the last couple days i've been searching this forum for a solution for my problem, but I can't find one. It seems like a lot of people are having problems with vibrations in their JKs, whether it's from the engine or the drivetrain.

My problem seems to be with the engine. First off, it's an '09 2 door, 6 speed, X model, hardtop. Has 2900 miles on it. I was in a small front end accident a couple weeks ago and these vibrations started about a week after that, don't know if one has to do with the other. Only thing i had to replace was the front bumper on the JK since it was a little bent.

Anyway, my vibrations from what I can tell are not in the drivetrain as when it's when i'm sitting still or moving. It happens at around 1500 rpm, no matter what gear I'm in. I've checked out EVERYTHING it seems. I've checked out the motor mounts good and they seem fine and not torn, exhaust is tight and all. the engine at 1500 rpm doesn't seem to move any different then at any other rpm, it's just noticeable inside as you anc feel the vibrations through the wheel and floor as well as hear it in the cabin. I have had no CEL lights and have had a scan tool hooked up to it and everything seems to check out.

I am really just dumbfounded about this. I have no clue what it could be. I still think it could possible me a motor mount or it might need an ECU reflash from the dealer. I have reset the ECU and that didn't seem to help.

I know this was a little long-winded, but I know on other post everyone wants to know exactly what is going on so they can help out. I hope all this info helps and someone can help me figure all this out.

Thanks in advance guys!

 

6 speed or auto? I ask because I had the same thing and it was a line from the manual transmision that ran up the firewall. The shop bent it out just a bit and vibration gone. Maybe your fender bender was just enough to move the line?.....Good luck

 

are you talking about the slave cylinder hydraulic line?

 

It is a 6 speed. I will look into this. I hope that it is as easy as that to fix. Were exactly is this line? Do I have to move anything to get to it? You're help is MUCH appreciated!

 

Nobody else has had this problem?
