Ever since putting the 19mm Ultrick swaybar (Good bar but god awful endlinks and bulky in comparison to others)
I have had intense squeeking which is so loud it can be heard from outside the car for about 30 or 40metres. I used the Lithium Grease which is the special grease supposedly that cures the squeek. What can I do, the sound is horrible and annoying. Should I buy some more lithium from an autoparts store and re lube the rubber and just coat the bar with it a few inches to either side of the rubber bushing?? I may even upgrade to a 22mm bar from another company as the Ultrick one looks bulky and seems to be too close to other suspension components and can't even be adjusted to the stiffest setting due to metal rubbing metal.
