brianZortiz Posted September 12, 2012 Share Posted September 12, 2012 I have had many differentials in my car. From 3.36 up to 4.11, all have had different yoke stiffness. Some were easy to turn by hand and others a little harder. Does the stiffness of the yoke affect acceleration of the car? I am assuming it kind of does, but im not sure. What is involved in making the companion flange/yoke less resistant? Is it backlash? Brian. Quote Link to comment Share on other sites More sharing options...
SUNNY Z Posted September 12, 2012 Share Posted September 12, 2012 Being that the relative humidity can affect the way an engine performs, in theory, yes it can. However you're talking such a trivial amount of resistance in the grand scheme of things, that I DOUBT it matters. The differences in gear will be what you will notice as far as acceleration goes.

johnc Posted September 13, 2012 Share Posted September 13, 2012 Yoke stiffness? Sounds like a male porn star. Are you talking about how much torque it takes to turn the input flange on the diff? Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted September 13, 2012 Share Posted September 13, 2012 It seems that as the years go by, it takes more and more torque to get the old yoke good and stiff. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted September 13, 2012 Share Posted September 13, 2012 Try adding a little more friction modifier to your rearend. The performance will improve, but your reaction times may be reduced. Quote Link to comment Share on other sites More sharing options...

brianZortiz Posted September 13, 2012 Author Share Posted September 13, 2012 John, I mean when you turn the companion flange by hand when driveshaft is disconected. I feel there is a difference on my diffs that I have owned, by turning it by hand some are easier to do than others. @Rebekahs, I will give it a try. I am using half 75/140(I think) and half Lucas oil stabilizer. Quote Link to comment Share on other sites More sharing options...
johnc Posted September 13, 2012 Share Posted September 13, 2012 That's normal. Could be the tightness of the seals, the style of diff, whether there's any oil in the diff, etc. Quote Link to comment Share on other sites More sharing options...
RebekahsZ Posted September 13, 2012 Share Posted September 13, 2012 Don't mess with your oil, that was a dirty joke but you aren't old enough to understand it. Your oil is fine-I was just messing around. Quote Link to comment Share on other sites More sharing options...
brianZortiz Posted September 19, 2012 Author Share Posted September 19, 2012 Thanks for the Help guys! EEkkk, It took a while to get the joke, guess I do need to grow a little older to understand it on the first encounter. Quote Link to comment Share on other sites More sharing options...
