rear end





Do you agree with this post? This guy has a little more experience than me or you on this subject.
One thing I would recommend you check, with the amount of endplay you report,is to see if the yokes are hitting the housing. This is important to check because if left with slop the yoke will grind the 1/8 boss off the housing and start on the seal, then you may loose the whole deal. No one will give you a dime for it as a core either.
Your problem is a very common one with these cars. How it is corrected,if it is,depends on the mechanic/owner. With that much wear in the yokes chances are the bearings gears and posi case need attention. It can add up real fast,from a basic $600 master kit job to Thousands for a 1000 hp deal.
My 69 yokes were so bad years ago, I felt the rear end sway in curves at 65 mph on the highway.

I am 52 years old. I was working on my homemade go cart when I was 8. Grew up in a farming family and have been working on mechanical things as long as I can remember. I was in honors math and automotive classes through high school, I took 3 years of automotive design and mechanics in collage. I have 35 years of experience building cars with a lot of custom fabrication experience under my belt. I don't have an engineering degree but I do have common sense, education and experience.
You posted this in post #89.
FWIW your credentials don't impress me.
I posted this in post # 97.
I really don't care if my credentials don't impress you. I have admitted I do not have an engineering degree. Just posted what I do have.
Then you posted this in thread #99.
This seems to be a pretty sensitive subject to you. Who brought up educations? Oh yeah, it was you. Yes, I have an engineering degree.
I had no idea before post #99 that you had an engineering degree. Actually it came as a shock to me reading your posts that you did. Both of your responses came off as arrogant and confrontational.
This informational thread has deteriorated and escalated into personal attacks and insults now so I am out of here.

The last time this issue came up we had a member that posted the holy grail hard numbers that a few of you non-believers want to see. That string was deleted in entirety, and the knowledge was lost. What a shame. I obviously regret not writing down the numbers when I had the chance to do so, but I could hardly have predicted the contentious nature of the subject on this website. I suppose that when I found out that I was so wrong about my half baked assumptions the need to prove it to others seemed unnecessary.
We have a member above 'Les' who is hoping to have someone chip in. I presume this person will do his homework and come prepared with proof not just opinion.
I see my name mentioned several times above, sometimes in a unflattering manner. Please do not speak on my behalf, or make assumptions of what precisely I have done or not done while researching this issue.
Let's not have this thread locked/deleted too.
it will be very interesting to see if some one can come up with this holy grail...

my prayers have been answered...

The Best of Corvette for Corvette Enthusiasts
I have the factory dana 44 in the front of my Bronco.
The pumpkin is offset from center. On the short side to the axle there is no c-clip because there's no travel for the axle to pull out.
On the long side there is a c-clip because under severe articulation it could be possible to really pull the axle stub to far out of the pumpkin.
I put a trutrac in. By their very design it is impossible to reinstall the c-clip when using a true-trac. All the Bronco guys and even the truc trac guys run it without a c-clip.
You can also put a truetrac in the 80-82 d44 rear ends.
All three came up with the same answer that confirmed the positive load on the yokes.
NO ONE has done the numbers and found otherwise.
I stopped my calcs at 1G, the other poster (who had done them himself recently) had continued to at least 1.3G at which point the yoke load did go negative.
It's a shame that entire thread was deleted. Still don't know why. Must have been the red faced table pounders.

The silence is deafening. Looks like I am the red faced table pounder that was right. Hope this ends this debate once and for all. An apology for the personal insults to my intelligence would be nice but I don't think that would happen in this lifetime.

Your reading or comprehension skills seem to be impaired also. If you re-read it, this is a MODIFIED CAR with inwardly offset wheels. This, combined with the tuck-under of the tire negates probably two inches of the lever arm the GM designed into the suspension to achieve the constant inward load of the halfshaft ***'y. This video helps my assertions, not negates it. The OP of THIS thread has a non-modified car so your 'we're all a boy racers' stuff is not relevant.
Here's what the OP of that other thread thought about you table pounders:
"I have now finally had the patience to fully read some of the other posts and threads about this, and my personal conclusion is that except for a few select members, most of them are keyboard mechanics with little knowledge about what actually goes on. They have their own big bang theory but make it sound like its a science fact.
"I couldn't have said it better.

.... Look, to be honest here, I got a couple of e-mails from another member asserting your expertise in this area after our last round of posting about this, and I do believe that you do have some expertise in this field. And I really did not want to upset you because maybe some day i may need some of that expertise, but i do not believe you are or have been taking into account every and all load variances on your modeling, there is so much more here than just up down pressures, you have twist and pulls and pushes and load changes in many different directions, there is a time that comes that you have to look at a video like this and sit back and re-think your calculations instead of trying to make excuses for them.
we have video now, we have people, yes like me, who went through this and fixed it, people like George that race and has attested to this on the other thread and i believe to be as big of an expert as ANYONE on this forum.
and we have contended many of times... many.... hard slalom type turns. not a leisurely cruse.
Again: http://www.youtube.com/watch?v=FIFZMa1pyX0
and after all of this you still think you are correct?
really?

Paul,
Again your best and only effort is to discredit people, this time it's the OP of the other thread and the people that have sent you PMs on the subject. I still have your PMs asking me for forgiveness about past rudeness. I thought you were FOS then, you've just proven me right. I did watch your thread on your brake fiasco and saw the same approach.
fordvicjr,
Please read what I wrote and compare it to what you wrote. You've again proven that you don't seem to be able to grasp any part of the discussion, nor did the diagram help. That's very sad. Since you like quoting sayings, here's one that fits: 'It is better to seem a fool than to open your mouth and remove all doubt.'
This discussion is now at the troll level, so buh-bye from me until someone has got some hard relevant evidence one way or the other.
I hear the Luddite society is looking for new members. I'll give them your CVs, the three of you are shoe-ins. Have fun!
