Sway bars contacting coilover collar? Adjust UCAs?

[KCcarguy]

I've been noticing an occasional metal-on-metal "ping" when i hit a large bump or dip at moderate speeds while turning.:...especially tight turns. This started after I installed my LR UCAs. I'm wondering if I changed some sort of geometry in my suspension that could be causing the sway bars to hit the collars when the suspension is compressed or extended while turning. This is pure speculation though (not a mechanic of any sort). Here's a pic of my driver's side in neutral position to show the proximity of the two parts. I couldn't see any signs of impact or damage. So...

-could I be right?

-any other ideas what it is?

-would adjusting my UCAs move the two further away and prevent this? I'm currently at the "D" position.

Did you install sway bar relocated kit, because if not that would be the reason the sway bar would be hitting the bottom of coilovers.

What Alex said. $30 kit should do it

Sorry, I should have mentioned I already have the SB relocate kit installed.

Here is the link where limamike was having problems with sway bar hitting coilovers too. I think his sway bar kit was installed wrong.

I'm pretty sure I've got it right....here's a pic:

That does look installed correctly, Does your C/O have misalignment spacers on the lower mount? If so make sure the C/O is offset to the rear(bigger spacer in the front)

I honestly don't know. I know I didn't put anything on when I installed them. Can you give me a pic of what to look for?

My Toytecs did that same thing on my Tacoma. Even with the sway bar relocation bracket installed correctly. It frustrated me so much that I eventually took them off. But I never stopped trying to solve the problem.

First thing that I noticed is that Toytec is different because their adjusting collar is on the bottom whereas ICON and others put their adjusting collar on the top. So when you adjust Toytec coilover down then the base of the spring gets closer to the sway.

I think the problem on my Tacoma could have been solved if I had used the next softer spring. (for example, switch from 700# spring to say a 650# spring). And then use the adjusting collar to crank up the lift back to the current height. I had 700# springs and therefore the adjusting collar was extra low.

Now, on my ICONs I currently run, they supply an offset collar with the coilover. The offset collar shifts the bottom mounting of the coilover more towards the rear of the truck away from the sway bar.

That is my experience.

Ah i think im getting the toytecs and icons mixed up. The icons have the misalignments spacers not the 5100s. But given the location of the rubbing(on the shock itself) im not sure what is causing it to rub.

Just and update: Yesterday, a buddy and I took the 4r out and did a little slow flexing/ compressing off road. We noticed the sound got progressively better as we did more. We put the truck up on a ramp in the garage and saw there was no contact between the swaybar and the coilover. Then, we put it up on jackstands and checked all the bearings, balljoints, and torque on all the nuts...everything was good.

We did see quite a bit of dust build-up around the base of the coils and collar (my fault) and decided the clanging noise was the coil-springs binding at the collar when the suspension was compressed. This makes sense because I usually noticed the sound early in the morning or after work (when the truck had been sitting a while).

So, I need to do a little better cleaning my suspension when I wash it. Otherwise the truck is solid and I'm happy!

Oh, yeah....and we cranked the coils up another 0.5" while we were there to compensate for the new sliders and skids.
