  • Rear end stress...

    I am sitting here bloated and sleepy from another wonderful belt busting holiday dinner wondering just how I can lift the rear end without stressing the banjo bolts and tighten them up. If I lift it from the banjo I won't be able to tighten the bolts because the jack will be in the way, and if I do get it up to a workable height with jack stands it will allow the banjo to sag putting the same stress on the bolts as driving does.

    How about thoughts from those of you that are in the same boat, and pictures if you have them!

      I think you're right Mitch. He ate too much and it has affected his logical thinking. Sorry Wiz, 2 alkaselzer, go to bed and come back in the morning.

      If it was my car i would crawl underneath and tighten the damn bolts. If they are leaking remove one at a time and seal the threads, but drain the oil first.

    Jack stands are placed at the ends of the axle tubes, then all should be normal.

      If I could get out there, I'm skinny enough to do it, without a JACK!---On second "thought", Vermin's not there anymore! I could clean the INSIDE of the KDodge Kadotas' WIDE Mag Wheels!

    Tom, I was thinking the same but the further away from the bend point, banjo, the more downward force in the center. The tension of the spring pulling the top of the axle housing up will only add to the downward force on the banjo.

    Looking at the rear end, knowing the tension on the spring, all the stresses actually force the stresses downward on the banjo.

    I am actually thinking that the banjo is what should be supported and maybe the closer to the banjo the jack stands are placed the less stress on the banjo and truer the torque on the bolts holding it together.

      I don't have a spring spreader. Also, all the videos of folk putting it together are without spring and set vertical to tighten the bolts.

      Setting it vertical aides in assembly and end play checks..

    I would just run it up on my lift to a comfortable working height and. . . If you do not have a lift just drive one side up on a high curb and scoot under there. Yep, overthinking about loading on the banjo. Jacking the rear up anywhere- banjo or axle tubes, will be less load than the inertial slam of the torque tube mass on the rear when a big pothole is encountered.

    If you do use jack stands beware of the lever release type- now linked to several accidents.

      Wiz just put the stands at each end like tom said take a jack floor would work put a small block of wood on it jack it up to put a little pressure on the bottom side of the banjo for clearance and tighten the bolts, not sure you really need to do this but for peace of mind go ahead not that much to it that way, I have a spring spreader but you would be dead before it got there after the last deal.


      • #7
        So your floor jack is going to be in the way? How about using a block of wood between the jack and the banjo? If your needing to get the car up how about drive on ramps, then floor jack and wooden block!

          That is what I said big hammer your point with the ramps is good as well.

        You really are over thinking this, but to much turkey will do that. If you put the jack stands under the spring hangers it would pretty much equalize all the pressure.

        To much turkey will also give you rear end stress later on.

            Floor Jack
            by Nabco
            Gentlemen, I am going to purchase a floor jack for my Coupe, should I get a 3 1/2 ton or is a 2 1/2 ton sufficient. Are there any specific ones that are recommended. I’m also looking getting jack stands, any recommendations?

            Thanks, Nick

            What is a good jack to carry along?
            by Jeff/Illinois
            Do you guys have any preference to a good working safe jack to take along in your Model A for changing a tire? Don't necessarily want or need to use an original.

            Got a good one that is compact and easy to use?? Where did you get it??

            Jack Stand Support Bases
            by Tom Wesenberg
            I have carpet in the garage where I park my Model A's, so when I store them on jack stands I like to have a solid base under the jack stands to keep the legs from leaving marks in the carpet. These also work to give the jack stands a solid base when using them on dirt or gravel. I cut a 10" square out of 5/8" plywood, and screwed thin boards around the perimeter to keep the stands centered....

            What do I pay for a correct jack
            by Great Lakes Greg
            I have located a correct jack and handle in my early '29 fine point tool quest. (A-17080-A jack, A-17081-A handle) I am not necessarily looking for a deal, and definitely don't want to screw my source on the price. What is the going rate for a reasonably nice, functioning jack and handle?

            hi could you tell me if this jack could be from A? I already asked that they tell me if they have any inscription

            Jack A-17080... Maybe
            by Jwmckenzie
            I have this Jack that is close to but not exactly the same as the judging standards. It is a Walker Jack. The jack measures 10 3/8 total height, the standards say 10 1/4. There are no holes in the flip top, and should have 7/16 hole on each side of the flip top. Based on research Jim Mason web page it looks like this might be a Model T jack, however Jim indicates the Model T jack doesn't have...

            Banjo gaskets, there ain't none.
            by Great Lakes Greg
            I tore down my rear axle for inspection on the latest restoration, and everything looks absolutely perfect, except there isn't a single gasket present on the banjo. Pinion / ring gear mesh is spot on, and the drag on the ring gear spin is also very good. If it is this close to being right on, are the gaskets really necessary? I suppose I could shim out the carrier bearings to make gaskets necessary,...
