Back in 2010 (wow, time flies!) when I put the front stabilizer arms together the hardware on the inner ends of the arms was in rough shape. I bought some nylon washers to replace the original leather washers and replaced the worn hardware. But ever since there has been a rattle from up there.
Here is that I put together back then. You can see one of the ruined washers at the bottom.
Here it is assembled. The mistake I made is the arm is too loose on the shoulder bolt so it rattles every time the car hits a bump.
The fix I made (nine years later!) was to cut rubber washers out of an old inner tube. I neglected to take pictures of this until it was already back together. But things are a lot more quiet now. I am not sure the rubber washers will hold up, but if they don’t I will make replacements out of leather.
