    Larry, I had to really fuss with all this when I needed to relocate the axle relative to the wheel opening on the Ranchero. Finding bits that claim they fit right was tough.

    I couldn't quite tell what I was seeing last time I looked and meant to ask for clarity -:but then got distracted and forgot to. I hope you have it all figured out now, but know you are always welcome to call and in most cases I'll come right away to give you a second set of eyes on something.

    Thanks Roger, I know you would help in a heartbeat, you always have. It was just a brain fart on my part to not verify the alignment.
    I got it all back together again. I was able to use the existing pin by running a 5/16 nut up against the pin end and then ground off the corners of the nut. It was exactly the thickness I was after.
    Took a little work to get the pins to align with the holes, but with a little prying it fell in.
    I did one side at a time to keep the rear end in place.
    Rechecked the pinion angle and it stayed the same. Driveshaft is 4 degrees up and pinion is 2 degrees down. Just what Quick Performance asked for.
    Got the traction bars re-set and now I might get some good weather to take it out and drive it. I am supposed to drive it about 5 miles at easy pace to warm up the rear end, let it cool down, and do that four times. Then drive it 100 miles at normal speeds before I do any hard launches. Attached some pictures. This time you can see the pin coming through the axle housing support.
    One is of my messy garage, every tool I own is on the floor I believe. Larry

    Got the Falcon out and drove it twice now. Per the Quick Performance break in directions on the rear end I need to drive it four times about 5 miles at low speeds to warm the rear end and then let it cool down. After the four trips, I have to drive it 100 miles with no hard launches.

    Nothing broke, lost some screws out of one wheel cap. Had one screw left, the cap was rattling when I got home. No rear end noise though.

    I am going to try and attach a youtube video of some nostalgia drag races in Tucson last night. My brothers Fairlane is in several shots.

    I think we all have a few screws loose, but glad to hear it's going well. When you actually take it down the track I wanna see a YouTube video of that!

    Drag Racing

    Not sure if everyone knows all the issues I've run into in putting a 9" rear end in the car for drag racing. I bought the housing and 3rd member with 4-11 gears and trac loc posi. The instructions said to drive it 3 times at low speeds for about 5 miles to break in the ring and pinion gears. I did that and started having all kinds of vibrations, noise that we couldn't figure out where it was coming from. Thought the drive shaft was too short. Got a new one. Thought a tire was out of round, got a new one. The leaf springs were weak, got new ones. Thought the traction bars were causing the pinion angle to be off. Bought Cal Tracs. Drove the car, just got worse. Finally sounded like it was going to blow up.
    Pulled the 3rd member, found ring and pinion gears were worn out. Sent the 3rd member back to them, free shipping back, sent me a new one. This time the break in instructions were a little different. Drive it 5 times at low speeds for 5 miles each trip. Then 100 miles at regular speed without hard launches. I was 74 miles into the break in and on the way home from the Maltby show, bunch of noise. Everyone that listened to it, thought it was something riding, like tires or something.
    Sent an email to Quick Performance and while waiting for a response, took out the 3rd member. Looked beautiful. No shavings, nothing. Quick Performance called me and told me it is just the posi discs causing the noise. QP has been fantastic. I have owned that setup for over a year. They could have just said too bad, but have shipped new rear ends to me at no charge. He told me several stories including his own brother had exactly the same issues I did, even told me that all of his buddies told him it was tires or something riding. He guarantees the clutches are the noise maker. Now I have it all reinstalled, will drive in around in figure eights at low speeds to break in the clutches.
    Hope I haven't driven you to tears with boredom. I will let you know of the results. Larry

    Larry, I think I know the noise you are talking about. I had that noise after I changed the fluid in my Isuzu trooper diffy. (Every time) Even though I used gear oil that was supposed to have the special additive for limited slip, I had to add a little more of the additive. It took me forever to figure out what it was. It sounded like the tires must have been rubbing. Drove me crazy for a really long time.
    Anyway, bummer about all the troubles. At least you have lots of new stuff!

    Don, that is exactly what the noise sounds like. Very loud though.
    Yep, lots of new stuff and finally got it all back together tonight. Tomorrow I will be driving it around if it doesn't rain. Now just need to try and finalize plans for the Nationals. Larry

    Larry, that's bizarre to have so much trouble. Are you sure you're livin' right?



    Just kidding.

    I hope this one works out good for you, but hopefully it can at least ride down to Sactomato and represent the club. I wish I could go.

    Of course I'm living right. Well maybe. Well maybe not. Must be, I'm driving a Falcon for goodness sake.
    That list of everything I did, is just the short list. Didn't get to drive it today, the front end fell off. Kidding.
    Didn't feel well enough to get out much. Will try tomorrow. Lots to do before I leave for Sactomato. I will let you all know how the noisy test drive goes. Larry

    Well, Roger, I would like to take you up on your willingness to help. I have two issues that I could use some brains on. I have been driving the car, and there is a vibration I can feel. I put the car up on jack stands and with the car running in gear, it looks like the drive shaft is wobbling. But, not sure if it's enough to cause the vibration. 2nd, I really would like you to drive the car, feel the vibration and see what you think also about the setting the clutch for proper engagement. Maybe? Please? Thanks, Larry

    Larry, not a problem. I'll touch base this week to arrange this with you.

    Over the last year and a half I have been haunted by a vibration in my car. It all started when I changed to the 9" rear end.
    We thought the vibration was caused by incorrect pinion angle. Reset angle. Nope
    Maybe worn out leaf springs. Bought new ones. Nope
    Maybe the tires were out of round. Checked that, a little bit out of round. Bought new tires. Nope
    Homemade traction bars? Bought new Caltracs. Nope
    Then the rear end started making noise. So, must be the rear end. Quick Performance sent me a new one. Nope
    A couple of weeks ago, I put the car on stands, put it in gear and watched the driveshaft. Wobbled all over the place.
    Thought I must have installed it wrong. Nope
    Had Roger and my neighbor (life long Ford mechanic) come over and look at it, and both said it looks bad.
    Did a check with a dial indicator and it showed the driveshaft was .070 out of balance.
    Called Drivelines NW and he said it was impossible. Now get this........He said their quality assurance processes made sure they are perfect.
    Well if you have followed this problem, you might remember that the first time they made the driveshaft they made it too long. Oops.
    They remade it, but this time instead of cutting it 1 1/2" shorter, they cut it 3" too short. Oops.
    So when he told me their inspection process makes them perfect, I reminded him of their imperfect production twice. Oops.
    So...I took this driveshaft down to them, showed him the readings I got with the dial indicator. He said they would check it, but it is impossible for it to be that bad, because if it was, it would vibrate the windows out of my car. I said "Thanks a lot" that is what I have.
    Now, before I took the driveshaft to them, my brother told me to put notches in the fittings so I could tell if they did anything.
    Today, they said it was ready. When I got there, they told me that there was really nothing wrong, maybe a 4-6 thousandths off, and one missing washer.
    But, what is weird? The notches weren't there. Also, the balance weights that were on it were rectangular. Now they are round. No evidence of them cutting the others off, no grinding.
    So, instead of admitting they screwed up, they made up a story and made me a new driveshaft.
    I installed that driveshaft today, and miracle. NO wobble.
    I will drive it tomorrow if I can and see if the vibration is gone. I will update. Larry

    Wow, what a painful story. Anyone who knows quality assurance knows there's no such thing as a perfect quality assurance process. And then why would they cover it up when they gave you a new one anyway? Strange...looking forward to the test drive.
