Rear end sounds like a Turkey call Reply #4 – June 10, 2013, 07:56:53 PM Hell, even I never soak the clutches in modifier, that shiznit stinks too bad. I soak in 75w140 synthetic and double up on modifier during fill; don't have problems.Protip: install the friction modifier before filling the rear end with gear oil. Quote Selected

Rear end sounds like a Turkey call Reply #13 – June 11, 2013, 03:11:39 PM Not bashing brands here so don't take it that way. Have you always run the Lucas rear lube? You might try a simple rear lube change. I run the Mobil 1 with a bottle of friction modifier and have zero issues. The Bird has 4.10's with the F-150 "Z" spring and the Coupe has 3.73's with a the stock Mustang "Z" spring and the clutches were stacked and packed when the rear ends were built.Darren Quote Selected
