  2. I hope that tie rod is greased well where it hits the spring! You don't want stiff steering!

    This axle does not look like it has been dropped. It is all too straight and neat. Dropped axles usually show at least a little deformation in the areas that have been stretched/bent. If I am wrong and it is a dropped axle, it is one hell of a good job.

    Of course, the other problems shouldn't be ignored..........

    Twenty8, looks like this is a 4 inch drop axle, I suspect there's absolutely nothing wrong with the axle. I think what it may be is a 46 to 54 Ford or Chev Pickup axle for use on a multi spring pack and when used on a 32 chassis things are different...especially with a mono leaf. Perhaps it needs a block to add the spring pack thickness lost...

    I share the link above for reference...

    That would only raise the frame and body up. It would do nothing to help the minimal clearance under the axle or the scrub radius issue. Remember, the wheels and axle sit on the ground, and the spring setup carries the rest of the car above it.

    That’s much more than 4 in total drop. I’d be thinking maybe 8 inches total assuming ground to the top of the axle is 4 inches ( based on the hand and gap from bottom of the axle to the ground).
    Either a good drop or made that way (aftermarket) and hopefully not cast.

    Pretty sure that might be an AD pickup 4” over stock drop. The axle itself looks good and I am pretty sure I know where it likely came from. Just appears to be the wrong application with no regard to scrub line or common sense on steering linkage.

    Assuming the axle itself is sound, that is an axle for a build featuring tall pre-WWII-style front wheels and tyres.

    It's already stiff, 'cause it's wearing through the tire!
     
  11. I am starting to think there is a question here !!! And he may have been concerned about his scrub line . Maybe , hopefully he is just in mock up ...
    I am currently putting a 4 inch drop axle in my 33 chev ,but I dont think I can keep the axle above the scrub line unless I use a pre war rim .

  12. I have a 52 axle in my 34 chev truck , pretty much the same axle other than king pin size
    Once I took off the 19 inch rims and put on 15 inch rims ,it leaves me about an inch and a quarter above the scrub line .
    If I put in the 4 inch drop axle it will put me at or below the scrub line .
    Have some serious measuring to do .
    The only way to correct this is to use a larger rim and tire .
    Oh Boy !!!

  15. With some measuring this morning , as I am installing an chevrolet axle in my 33 chev .
    The axle has a 3 inch drop and with 15 inch rims it will hit the scrub line . Might gain 3/4 of an inch as long as the flat tire stays under the rim !!!
    Anything much greater than a 4 inch drop is pretty much a no go .
     
  16. This is a 52 front axle in my truck , it is I identical to the 34 axle other than larger king pins and heavier tie rods and drops .
    With the 52 axle you can see I have 3 inches of clearance, if I install the 3 inch drop axle ,I will be sitting on the scrub line . The tie rods are already below the scrub line with the stock axle. The laser is set at the bottom of the axle for all pictures

    Just mount a HF caster under the axle if your worried about scrub line. :D
     
  18. Guess mounting the HF caster worked under your car ,but I will pass on mine, and yes the scrub line is a concern as it should be !!!

    If a member has been here since 09, perhaps built that Truck in question, has been a lurker all along gleaning from Threads to build what I see as overall a pretty cool Hotrod...why would he not expand a bit on his end goal here...is it a rant Thread?

    I get that we're all over the place with opinions...what else is new...

    I'm not a chassis guru but when I see a bolt with 4 nuts as spacers on suspension/steering components I share the concern of many here...is using a dropped axle for a 55ish chassis on a 32 an issue...Hotrod is largely based on using parts from anything and everything but at the core of that is correct function.

    If it was my ride I'd have said I am in over my head here...but some have no words...hence we are left to comment...pretty much entirely unaware what the OPs intent was...

    ...and still not a word...good luck to anyone driving anywhere near that as it remains...IF it is in fact on the road...

    I guess the thing to glean from Threads like this is Posters please state what it is you are looking for when you post Thread with a Title and 2 pictures which are basically inadequate...Commonwealth aside.
     
  21. There is far scarier work done on build threads here daily with folks cheering the OP's on. Is this truck right? Naw. Some minor changes would make it worlds safer (as in those stacked bolts) A whole lotta rods and kustoms have scrub issues. Sometimes you gotta pay to play.

    Whats your deductible? The truck has a nice stance, but it carries a death wish.

  23. While we’ve been on the subject. The m looking at doing a dropped axle on my 49 gmc. The 4 inch drop looks sketchy due to scrub issues.
    I’m leaning towards the 3. The above pics suggest it would also have a scrub issue.
    The steering arm issue is interesting.
    I’m thinking on 3 inch posies springs then maybe have the axle stretched a couple inches.
    Or forget it all and go OT

  24. A single posies spring or traditional 7 leaf stacked spring will not change the the scrub line of the axle. The spring sits on top of the axle .

    So the drop, rim dia and tire size dictate the scrub factor in my assuming mind...

  26. Your tie rods clear now and will after the drop axle install , would have to be bent to clear the leaf spring though . Probably made to pass between the leaf spring and frame.
     
  27. Rim size and axle drop , tire would have to be flat before scrub line comes into play

  28. Mine has the axle under the springs.
    A spring can affect scrub. By using a drop spring and a less stretched axle, you gain scrub over doing all the drop with the axle. That’s my plan anyway.
    Im not slamming mine like I normally do.
    If so, I’d be doing something OT

  29. It will lower the body but wont change the axle scrub line

    With respect, a bad idea is a bad idea, no matter where in the world you are.
