The problem with those cheap control arms is that they are not built very strong. Also, having poly bushings on the both sides of the control arm will cause it to bind. Im not surprised these bushings went out, and youll probably end up replacing these things every so often until you change those control arms.

I never considered what other parts you might have. I know it's more money but I would recommend Something like MM lowers with spherical bushings on one end. Stock uppers are good and you want rubber bushings on the axle side.

there's still some but nowhere near as much. gonna recheck more tomorrow as the bolts were loose when we started today. so just for safety sake.

Prothane trans mount on a t45 is a horrible idea. If you make enough power and can get it to hook you risk snapping the tailshaft off the trans.

Don't know how much power your making but I'm around 600 at the crank and run the stock mount with zero issues.
