Its the BMR non-adjustable bar.

So I solved this by placing two washers as spacers/shims under the lower frame mount bolt and it was immediately 98% quieter. And the rear suspension loosened up. When I bounced the car with the trunk open I had more movement from the bar not being so tight.
I need to look at the adjustable end links and the lengths as I had to make them a tad bit longer because the bar wouldn't move to meet the rod end when I initially set them to match the OE end links. I appreciate the tip on the interference with the knuckle I'll be looking at that when I'm under there. |

My BMR rear endlinks are offset and clear the knuckle when installed correctly

I reset the end links to OE length and installed the R side at full droop. Set the L side to OE length but left it unattached at to the bar. Reset wheels and dropped the car, drove it around the block and came back and put it up on ramps so that the suspension was loaded.
The L link at the SHORTEST was too long to reach the bar about a 1/2". I was trying to get it "neutral" on the L side. I had to jack the car, on the ramps, about an inch to be able to get the link bolted up. I revisited my washer shims and found only one was necessary to free up the bar and it would now rotate in the bushings with little effort. Still not prefectly quiet on that R side bushing, I may have to get back in and grease it again. Trying some WD-40 to verify. Keeping this going so others can try and learn from my mistakes. |

Yes where you circled is where I placed one washer, maybe a 1/16th in thickness, a washer was the easiest thing to use as a shim. Until I shimmed it the bushing and bracket were so tight that you couldn't move the bar by hand, I don't think I was even able to force it, it was so locked in position. That caused the squeak and also forced me to set the links LONG because of where the bar was. The rear of the car was super stiff, too, I could hardly bounce the rear with the trunk open.
The shim freed it up and I was able to get my links back to OE length. Everything has been 99% quiet every day this week. |

I had the same noise, it was driving me crazy. Read multiple threads doing research to try and find the issue. Bought rubber boots and synthetic grease for the heim joints. Didn't fix it. Then loosened all the hardware with the car sitting on the tires with load on the suspension still had the noise. Then cam across this thread and tried the washer trick, that helped loosen the swaybar but still had a squeak. So as a last resort I removed the BMR end links and reinstalled the factory and also sprayed WD-40 on the lower control arm where the spring sits. Finally I have no squeak anymore.
Just my experience. |

I was about to put the OE end links back in when I found a discussion about shimming the frame mounts and how much the bar should be able to move. So far so good, everything is about 99% I think I can still hear some sort of noise back there but Im done looking, I think.

If anyone is interested in the boot for the heim joints here are the part numbers for the items I used. Be sure to get the spreader tool or you will be hating life.
Also forgot that I found the upper trailing arm was rubbing the spindle pretty bad. Rubber boots - SIT-RERS36PK Synthetic grease - UPI-3008 Spreader tool - SIT-RERS-TOOL |

I too am getting unwanted creak sounds. I have all BMR links and upper control arms along with adjustable end links. Had 2 mechanics look at it and said everything is tight and to spec. Put endlink to ZL1 sway bar. I may go with putting the oem endlink back on from reading all of these posts. Before the sway bar and enlinks, did not make any noise so I'm going with them.

I was almost certain it was the rod end link, my first experience with that type. I lubed and considered the boots, I was at a loss. I pull them off the car, and to my bench where I was able to manipulate the rod end in its range of motion and it was silent. I noted to BMR states that their rod ends are teflon.

Well found out, mines not BMR related. It's my rear shocks going from all the links I put on it to stress it even more. Thinking about the Bilstein B6 shocks with afe power springs. Anyone have Bilstein?

That doesn't make sense. How could any suspension links add stress to a rear shock on our cars?
