I put them in today, and all I can say is wow. The car just feels so much better. Now I have to endure the torture of not really getting on it for a few hundred miles.
Hey Hotty, what brand did you get??
Ive put about a hundred miles on them and so far so good. They whine some but my exhaust is so loud that I can barely hear it at most speeds. I pulled the fill plug yesterday and so far no metal pieces, yay!!
I dont have to drown out the noise, it really isn't that loud. And as a lot of people have found, the gears with step cuts on the back of the ring gears i.e motive (FRPP), pro 5.0 and others will wine some no matter how perfect the pinion depth or the backlash is. I wou ld have gotten motorsport gears but ford doesn't make a 4.30, the only ones I have ever seen from ford were made by motive, hense the M on the end of the part number.
I installed them myself and I made sure everything was as perfect as it could be.
+1 for gear whine not normal, and as far as break-in time the gears are already tempered, and on a good install not really necessary, but it doesn't hurt either i guess.
Put mine in and went right out on the street and test beat the damn things immediately.. No break in for me.. Break for me is my burnout thats done just outside of the garage. I guess it could be called the first heat cycle.. lol
