I got this RC trac-bar a little over a year ago and the heim joint seemed to freely spin around when I had it disconnected from the axle. I've heard a ton of bad things about this trac-bar, mostly saying that the heim joint wears out quickly. I have pretty bad DW starting at around ~40-45 MPH, and I know trac-bar is a good place to start. The polyurethane bushing side going to the drop bracket seems fine. Does anyone have any suggestions to remedy this problem, such as a better quality heim joint or should I just replace the whole damn trac-bar with something better?
Also, I should add that I started having DW before I swapped axles, and still have it now that the new-to-me axle is installed. So, don't *think* hubs, ball joints, etc. The UCA's have new polyurethane bushings axle side and the stock, 26 year old rubber bushing frame side. The LCA's are Rusty's with the bend and rubber bushings (seem to be in decent condition).
