Did you figure out what was wrong with the Yukon gears? Pinion Wobble?
I have a set of Visteon 3.90 gears, I bought a while back, came out of one of Dale Jr.'s DEI cars. They have the Remedd treatment, look about like Chrome/Polished, very nice quality.
I'm not going to use them, PM if interested.
Yes, the Yukon gear is bad. I am sending it back. I used all new bearings, and a brand new pinion suport and it was wobbling. So, I had an old support with used bearings and an old pinion still in it. I checked it and it was dead straight. I took it apart and put the old bearings on the new pinon and set it up in the old support so that the only thing that could wobble was the pinion and it still wobbles .001". Thats not acceptable in my book. The snout shows uneven wear marks were it is moving from side to side in the case bearing, and this is just from me spining it by hand checking the pattern. My back lash was all over the place and so was the pattern. Like I said in my other post the Motive that I just had in there setup a lot easier and did not have run out, back lsah was also the same all the way around the ring gear. The Motive was just really noisy, and had been run with my bad axle. I bought it from Summit, I knew they would take it back so I went ahead and got a new gear. I bought the Yukon that cost more money because of thier reputation thinking I was getting a better gear. Guess not....Now I am on the hunt for another R&P. I may have end up trying every brand before its all said and done....
