I am pretty sure the rear end is from a Ford pickup. I see that there are gears for a dodge and a different set for a ford. Anyone know what the difference is? Page 21 http://www.motivegear.com/pdf/LD_DIFFCAT_011_1.pdf It appears that For 3.54 it is the same dodge or ford but 3.55 is different? COuld this be part of the problem?

I even called them and they wont guarantee there gears to be quiet. They told us to run 250 weight oil. What a joke. I wont even put a set in any more. We had no problems when we were using Yukon gears. But the motive's were cheaper so that's why we started using them, After many hours of playing with the pattern all to find out the noise wont go away. I had used motive many years ago and didn't have a problem but now there gears seem to be junk. And this isn't just 1 set, I have had this happen on at least 15 - 20 different diffs.

Motive bought Richmond and now there cheaper gearsets are Chinese made Richmonds basically. The Premium line of Motives are the ones to use but are unsually $240 plus. Mopar to the bone!!!

JMO... but I dont call that pattern good... it looks like the surface is irregular... the edges of the test area dont show a smooth line... it very well could be the gear set not ground smooth
