JMHO, of course, but based upon my experince if I were you I'd just replace the TF bushing. No more difficult than doing so on the weaker stock bar. It's pretty simple. Use a small shop press, or even a ball joint press, to push out the center sleeve, leaving only the outer sleeve and the rubber bushing. Use a hack saw or your Sawzall to cut through the rubber, then cut a groove through the outer sheet metal sleeve. Once the interference is relieved by the cut through the sleeve it'll pop right out. Press the new sleeve in, voila, done.
Based on my own 45k mile experience you can't beat the Teraflex track bars. Set 'em, forget 'em. I ran their first gen front bar for over 40k miles with no issues whatsoever. When TF's guys discovered I was still running it they sent me their new one, which is pretty much the same but moves the adjuster further towards the axle side attachment point. I was asked to send them pics of the old one cut in half at the adjuster. To do so took four Sawzall blades and a shattered cut off wheel. If people broke those first generation Teraflex Monster track bars they must have been real animals on the rocks, 'cuz mine ran every trail from Mt Blanca to Moab without a single issue.
