Ever hear of poly bushings splitting ?

[1969to2010]

I have a suspension issue, I posted about it before
My car pulls left and right at wide open throttle and feels slightly elevated as well
Def not a cool feeling the higher boost in run the more out of control it is.
Had the car aligned a few times and also discovered my toe links were loose
One alignment the car stopped doing this but the tires rubbed next alignment was spot on perfect but the car did the same thing, tightening the toe links helped but at that point the alignment was def off

My next step is timing the bushings and new alignment specs from justice Pete and lock tite on on the eccentric bolts plus I need tires so a trip to group a is soon too
I think this will fix it just haven't had the time
I'm trying to cover all the bases before

Sorry for the long back story but some one had suggested a split bushing could be the culprit has anyone ever heard of this happening ?

My car
2010 SS t76 499/556 rwhp pfadt springs rear sway bar BMR full poly subframe bushings toe links trailing arms trailing arm bushings running 11 inch forgestar cf5s with 315s in the rear

Any help will be greatly appreciated
