Well, after installing my 2.5" Teraflex coil lift a few weeks ago in my garage, I started noticing some extra noises, especially when going over speed bumps and also when starting and stopping. It didn't handle too badly, but what did I know, since it's the first lifted vehicle I had ever driven. After finally getting a chance to get underneath it today, I found that the rear lower control arm bolts were loose. the two on the axle were completely my fault. After following the installation instructions to the letter, I had installed the rear bump stops while the wheels were still off and the jeep was still on the jackstands. That meant that after the jeep was back on the ground, the only way to tighten the bolt was with a wrench since I was too lazy to take off the bumpstop and even a socket would not fit in the space between the bolt and the bumpstop

So today I finally took off the bumpstops and put a 21mm socket and impact wrench to tighten up that sucker on both sides. She is now completely noise-free from the suspension, and feels much tighter as well. It drives like a different jeep. I'm a happy guy!

I think the Teraflex instructions should be updated so that the rear bumpstops get installed AFTER the control arms are all tightened up.

 

hmmm...I have to check mine now. I get a weird clanking on bumps also.

 

Even if you did forget to tighten your bolts down after doing the lift, you gotta check that shit after a couple dozen miles, and then a couple hundred and so on.. Use loctite and a prayer and don't forget to check your nuts (for cancer/loose-ness) and bolts for being loose. When you get a free moment, slide under there with a socket set and see if you can move anything. One day you'll catch something that isn't right.

 

Everyone always says make sure you loosen the control arms when installing the lift. I didn't and it turned out just fine.

 

You don't really need to with about a 2.5 inch lift, but it will sure help a lot when you start dealing with larger coils. I didnt loosen my control arms when i put on my leveling kit and it was a huge hassle to get the rear coil back in, than when i did my 2.5 inch lift I loosened my control arms and it made a world of difference.

You should do this every few thousand miles or after a good wheeling trip. You will find something eventually and it could potentially save your life.
