[QUOTE="Fopar, post: 15874152, member: 152080"] Chiming in on my experience, just finished my complete IRS rebuild with FTB delrin/aluminum bushings throughout. I rebuilt the diff my self, ALL new bearings, seals, Ford racing 4.10s. Perfect pattern, backlash .007-.009 . As soon as I started driving it I noticed the driveline slack. I think it's generally been understated thus far how insanely bad it is. I took out a clapped out stock IRS, with gears that had .017" of backlash and front diff bushings so beaten up you could push the front of the diff up and down with your hand about .2"... and the backlash from this trutrac is easily the same as that setup or maybe even worse. I actually jacked up the car after about 50 miles of driving just to check on it as it had started popping while I left a light in first in addition to the general driveline slack. I used my digital angle finder to measure the slack, I found you could rotate the driveshaft a full 15 degrees before the inner CVs would even start to move.... If I had known it would be this bad I would have chosen another carrier... Future buyers beware. Good for a track car, but if you want something that doesn't jerk you around while you try to go through a frickin parking lot stay away from this limited slip. Pic is of my pattern for reference [/QUOTE]
