I have a Solid Axle CV on the Front and a IFS CV on the rear, I'll look into the rear CV. Maybe its still not enough? I have the stock Axle in the rear still running coils. 5.5 Fj80 coils, 2" spacers, allpro links and other misc brackets. Pinion angle isn't the best. Maybe i'll pull the rear driveshaft and try running just the front and see if it does it?
