So I just installed the teraflex 2.5 inch lift 1352000 springs with shock adapters. Now I'm getting a noise it's sounds like a spring being loose. When I hit a bump there's a boing noise sorry that's the best I can explain. Any help would be great. Maybe the springs have to settle I don't know.

 

Retighten/check the adapters on the shocks. Is the sounds coming from the front or the rear?

 

It sounds like its coming from the front.

 

Did you tighten everything up after the Jeep was sitting on the suspension wheels on it could be your track bar. if you tighten the track bar while it was still up on jacks it could be in a bind and cause a pop sound.

 

After the install I let the jeep down on its wheels and tighten everything back up. I don't know what it could be

 

Check your links in the front on the stock bolt it's very long maybe it's hitting the spring.

 

+1 on the tightening. I put my lift on and then was going to re-tighten at 300 mi. Started to hear, what I think, was a similar sound from the front right of the vehicle...was most notable when turning a corner and going over something, like a driveway... Got under the jeep and found that my front right swaybar link was slightly loose. I made the rounds and re-tightened all the bolts and never heard it again.

 

Mine did the same thing. Then stopped after a while. Call the teraflex folks they are awesome with customer service. I called them about a spring question and the guy spent two hours on the phone with me just chit chatting about all things jeep. Awesome company

 

I heard something when going over a bump after installation also. By rocking up and down on the bumper corners (while parked) I was able to isolate it to a sway bar link which needed some more tightening.

 

I had a similar noise after installing my TF leveling kit. I re tightened the sway bar links and the noise is gone. It's been quiet for over 4k miles now.
