Happy Labor Day, guys.
I've been having an issue with my trac bar setup that has baffled me for some time, and has occurred with multiple sets of bars (two CPP sets and a custom set, in lengths from high 70's to mid 80's) . Rear attachment points are bottom-U-Bolt brackets and front points have been both thru-frame bolt brackets and the over-the-frame U-bolt style.
No matter how much preload I set, or how tight I get the jam nuts, they quickly loosen up and start rattling like a SOB (and not doing their job). I've scribed a mark on the frame to make sure it's not the front bracket sliding under load, so I've narrowed the problem to the rear.
It almost seems like the load on the rear u-bolts is shifting the rear axle downward, throwing my pinion angle way off and putting an S-curve in my leaf pack. I'm out on the pipeline, so I won't be able to accurately check my driveshaft and pinion angle until I get back home to my shop/tools. What is the likelihood of this being the culprit? Anything else that I'm overlooking?
Thanks in advance.
