    I don't see that with my phone upright...If I turn it I see that...yeah whatever...I think since this scrub issue was shared it should become a sensible item of conversation...we should strive for a better situation on our rides...this is truly not modern tech...this scrub stuff and furthermore hiems and tie rod ends and bolts all play a part...Gene mentioned the experience he had with it...its tech dammit!!!

    It's okay to be reactive a bit in my opinion...and I like to see what others have to say, heck it may save a life...

  2. I actually didn't know the proper definition of "scrub line"
    Always learning something new on the HAMB!
     
  3. FWIW......I've built several hot rods with parallel leafs/beam axles. There are only a couple ways to lower them.
    1. Dropped axle. We see in this thread some of the drawbacks. Mainly scrub line, tie rod clearance, and braking lever effect. Scrub line issue may be overcome w/ taller wheels, but that negates much of the drop, IMO.
    2. Springs. Mono leaf, de-arched etc. This works, but only for a mild drop. Steering geometry may need to be changed to avoid bump steer.
    3. Axle on top of springs. This is the best I've found for a deep drop. A C notch is usually needed and you still need to watch the scrub line as the springs are now the lowest point. Steering geometry must also be corrected.

    Gene, This...
    Is Exactly where the quote "A Wiseman, Is only a fool with a good memory" comes from! Well put Sir.
    Funny How wise I feel...

  5. FWIW.....
    1. Any dropped axle (or dropped spindle) can have the same scrub line issues. Not isolated to just parallel leafs.
    2. & 3. Agree that any changes from stock height may need steering corrections for bump steer, geometry and clearance issues.

    4. (Added by me) a cross steering design is less susceptible to the bump steer issues, although it can still require some geometry or clearance adjustments for optimum steering and suspension travel.

    About braking lever effect: it's counterintuitive because those stretched axle ends feel spindly and springy, but I've done the math, and the torsion in a dropped axle beam is actually less than in a stock axle. The position of the spindle will throw you out, but it's irrelevant. The net lever arm length at work is the vertical distance between the tyre contact patch and the cross-sectional area centroid of the axle beam, which is shorter on a dropped axle given the same tyre diameter.
     
  7. Scary stuff!

    That's great Rusty, me as well, as I mentioned earlier at a minimum the images provided help educate us here building Hotrods and Customs and it makes for great discussion with the images certainly highlighting some of the problems that can arise lowering a vehicle...

    It also highlights not everyone understands chassis fundamentals...and if you want to attempt it do your research...

    A shout out to Hambers is there anyone out there with a Hamb Friendly Hotrod with similar, year, stance with parallel leaf and beam with pics of how they overcome this?

    A larger diameter rim (way off topic) and a short side wall tire would solve the scrub line issue, and ONLY the scrub line issue. The bolt, and all the other suspect work is just piling on.
    I believe if you start a thread with “Death Trap” in it, you are not scared away by the responses, nor are you interested In a fix, nor are you debating the laws and merit of Canadas vehicle code or the stylistic virtues of dropped Chevy axles or lack thereof. You are merely pointing out crap work. So to the op I say, well done. ​

    We are supposed to be a vintage Hotrod/Custom site...Large rubberband rim crap has already been shared and executed thankfully...that is not what I'm asking

    I'm asking of those in the know for a Hamb Friendly fix for what we are looking at while maintaining a similar stance and to me it involves an axle change, with a taller tire combined with a spring perch adjustment.It almost looks as if it's to low as it is now.

    If the OPster was highlighting a butcher job so why not show us what he did to remedy it...not everyone here is fluent in such things...maybe your right he's good with it who knows...

    This is why I asked our Chassis Trained members to chime in and expand on righting what is something anybody buying or building may encounter...

    I'd also like to point out that axle being used is I believe a Ford axle as Chev axles don't share that constant 'I' rib in the OP

    I'll be the one game enough to say "that much rake looks shithouse". It looks like the front end has already collapsed.

  16. So many posts. The obvious answer is strip all that shit off and start over. A perfect example of trying to polish a turd.

  17. I just noticed that this is in the Traditional HotRod forum. I must have missed the traditional part. Geeze.

    Noted...goodbye...;)...moral of the story...don't do this...:oops:
     
  19. A great example of how a Ford transverse leaf spring crossmember and front end setup would make a Chevy sit better and drive better

    Thread was posted on Monday 28 March...and the pics are apparently real in my opinion...I don't think anyone would have done that for a joke...Keep your eyes on the road your hands upon the Wheel I say...;)

    As Chili and others have said it needs a purge and reconfiguration by someone that gets it...

    Literally it's easy to get caught up in one...:D...but I don't believe this was a joke nor a sensible Hamber...

    And I agree, bad tech/design
     
  27. Don’t upset Stogy- he is one of the hardest working hambers out there.

    Thanks Daylate...Threads like this are frustrating...but I thought there was some positive discussion out of it all...and again this fella never come across as this type in the few other posts he made...somewhat strange frankly...I'm surprised nobody knows of this truck or Hamber in California...someone mentioned the Wagon, it is a strange model as that rear side door is extra wide...what is it ?

    I note 'Cali' Dream'n and Californian's largely hate that slang...ask me how I know...
     
  29. Yeah. Hard to tell if it is legit or not. Some days I have patience for it, some days not so much. You do a lot of digging, and it is appreciated, at least by me.
