I've got a 2012 Jk 2 door 3 inch lift and every time I drive it around corners, there's something popping or shifting and causing a thump or pop coming from the back end it has a 3 inch coil lift track bar relocation bracket new shocks and springs new sway bar end links. I can't find out where the noise is coming from except its in the rear end please help.

 

Do you have anything in your storage bin in the back? I keep my receiver hitch, hitch pin, and strap in mine. Every time I turn a corner the receiver or pin makes a noise like you are describing.

 

Yeah it's actually full of stuff. Reciever, winch remote, straps etc. but I just recently started hearing it and the bin has been full for months.

 

Check your trac bar bracket bolts. Mine loosened up. I tightened them up and added thread locker. It lasted for a few months, now its loose again. I'm not sure what the next step would be.....

 

Weld it...

 

On the passenger side rear,check to see if your coil is making contact with track bar on frame,also check your sway bar link,they may be catching your brake line(hard line)

 

Springs set in indexing location. Don't ask how I know this !! Cheers

 

Indexing location ?

 

I had this problem to I tightened my track bar bolts and it solved the problem. Goodluck!!

 

It's a lip/notch on the axle that the springs sit in...
