    Iíd have thought itíll be fine without a slipper, as all the pivot points match the lower 4 bar mounts so canít see how the length of arcs can be at odds with each other.
    I had something similar on my 123e, but in fairness that only had about 2Ē of travel so didnít ever have enough travel to show up ant problems

    Definitely wont be fine Chaley, if axle raises & falls equally it's fine, lift one side & drop the other (you wont be able to) then the triangle sides need to change length - but they can't without the slipper joint. Results are either: broken rose joint at chassis end, broken bracket at chassis end or broken rose joints at axle ends.

    The issue is the axle rotates around the centre point between the 4 bars whereas the locator rotates around the lower fixing of the 4 bars. Two different axis of rotation fighting against each other.

    Cheers mark, it must have been my very limited suspension movement that let me gat away with it, or maybe that’s why I had no movement

    Yep, till they break they make excellent anti roll bars
    Your limited travel combined with low mileage saved you, but it will break in the end.

    So if you raised the whole wishbone so that it aligned with the axle's axis of rotation it would be OK? (Except that it would probably end up fouling the propshaft!)

    Myles, correct, it would be ok then, though it would still need a slipper joint.

    I'm not a fan of track locators, they are perfect for the strip but on the street not so nice. Even with a slipper joint they mess with your roll centres, below the axle line increases roll and above reduces roll.

    For more in depth reading on all types of axle locator this is a good article;

    Hi Guys.

    Just read the comments regarding my "track locator" . Firstly I am the first to admit I'm no suspension engineer
    But... when this idea was put to me I needed to see that other hot rods have and were using this set up .

    One very well respected hot rod builder and very clever man has this set up on his own car also a very well know hot rod business has also used this very same set up on "customer " cars . So I was sold !!!!

    I also realise that I'm not building a car to blast around the forests of Wales or like wise to race around Brands Hatch .

    It's a HOT ROD !!!!!!!!!!!!!. ( remember the 70s/80s when guys bolted /welded superglued Jag IRS to the back of their Pop ,Escort etc)they were't interested in handling .......it just had to look good .Thankfully we have moved on from there

    Back to mine truck , The whole assembly was tacked together to check to see if there were any flaws in the design ( DID IT WORK ????).
    Yes it worked , it worked fantastically well .With the bags removed and a scissor jack under the diff I was able the move the axle up and down equally then I pivoted the axle ( at different heights) to replicate roll . The amount of travel ( without the bags ) was from 0/320mm , a massive roll it will never ever be that much . Don't forget it is still only tacked together , I then clamped pieces of box section at intervals across the track locator to see if there was any torsional strain along the tubing . There was no hint of movement .
    I then put the axle at ride height and pivoted the axle trying to replicate " normal " driving ( upward travel with one wheel dropping into a pot hole etc ). I have approx 150mm of travel , far more than most hot rods !!.


    So as I said it might not be the suspension engineers dream set up but it works on my truck .
    I then fully welded the whole assembly together it did the same checks .To say " IT WILL BREAK " I'm not so sure !!!!!!!!!!!!.
    I could have used a " Johnny Joint " for the front pivot but the amount of miles the truck is likely to do , I'm happy with my version .

    Unless I have made something " unsafe " I will be keeping this set up .When its finally on the road it will be constantly monitored ,if it doesn't work or has undue characteristics I will change IT .
    Thanks again guys .

    hi mark

    anything can break.diagonal location bars as supposed to break and be a no no on the street,but they work under tens of thousands of cars driven on the street.

    track locators seam to be the same.ive done a couple and made them with the slip joint,but these are drag cars,where the rear can really twist violently.

    if you've cycled it and nothing binds,thats all the answers you need.

    what everyone seams to over look in discussions like this is rose joints. rose joints fail.if there not covered and protected,they can lock solid.

    ive seen some corkers through here.4 bar rear end.all rose joints.every one has seized,so one snapped.even funnier was they welded it back on and kept using the car.

    johnny joints are superb.i use them in higher end builds here.
    Rod/custom/drag build profiles:
    Mini | Pop | Porker | Trike | Morris 8

    | 48 chevy coupe | ford f100 | tube chassis,d pop

    Mark, Well if you have checked it twists without binding then all is ok

    Wayne, track locators will break, but only after a certain amount of time/fatigue. The thicker the mount/size of rose joint will dictate how long before it breaks, most rods are not driven enough to get to the fatigue point. I have seen quite a few broken ones though, also seen a few slip joint ones ripped out of chassis - but this is because the slip joint had seized.

    Johnny joints look really good - would they retro fit in a std Urethane mount (IE could you undo the urethane rod end & just wind in a Johhny joint & bolt it back up).

    Hi Guys , I really appreciate the imput Ref ... my track locator . All I can do is monitor it to check on binding ,fatigue etc . As I mentioned before if I thought this was unsafe etc I would not have continued with it . Thanks again .


    Next task was to make a new rear cross member .....why ???????. I had only ever tacked a piece of 4x2 box section in place but as things have changed and evolved with the truck bed that box section wouldn't work.
    The main reason that it wouldn't work is that as the bed gets fitted on to the chassis because of the curved shapes that go under the cab
    its a pig to get it under the cab and over the ends of the chassis . In an ideal world the bed should be fitted before the cab but on final fit this is not practical .
    So the best way over this is to cut 100mm off of the chassis legs and make a new rear cross member with a removable mount for the truck bed . This mount can be easily fitted when the truck bed is positioned over the chassis rails . Hopefully the pics will explain better than me ,

    Rear cross member.



    Rear cross member welded in .It was shaped to match the exhaust outlet shape in the centre of the truck bed.


    Next the removable truck bed mount.




    The next task ( which i had been dreading ) was to make a grille !!!!!!. Because the bonnet an pretty much everything has been modified .I couldn't buy a grille from the states , so have had to make one
    I had some profiles laser cut from my patterns but untill I started I was unsure how much modifacation I would have to do to the profiles. I also knew that I would have to cut my own pieces as it progressed !!!!.
    A pile of grille bar profiles.



    So this is the start of mocking up the grille.



    I cut a lower mount from 3mm s/s which helps hold the grille shell a little more rigid as I try and get things to fit .
    I cut the top section from the same s/s but in two pieces ( I forgot to take a pic of them before they were welded together but the cardboard shows the shape I started with.






    Next task is to make some mounts for the grille shell then move onto the grille bars.
