After posting on the Flex Thread, Gerrit Loubser made some observations/comments that make sense.
For the sake of keeping this build thread up to date, I'll post some of the pics here as well.
I know this is really drawn out, but we are working at the speed of my budget, which is basically non existent. So if any of you want things to happen any faster, let me know, and I will send you my banking details
I had pulled the Sani over a bump in the back yard and it looked ok, but I have been wanting to get my garage in a better state to pull out my 500mm high ramps to get things tested in a bit more controlled manner.
This is what happened.
The pics...
Here is the major problem of getting the MQ to flex under the Sani... Shocks don't have enough travel. These are standard Disco 2 shocks, and with this little flex, I have compressed totally on one side, and fully extended the other side.
Rear end is still Hardbody, so I am not sure how that is going to change once the Patrol Diff is in.
Leaf spring compressed flex on the front...
Rear view
What does make me feel slightly better about the test, is that the left rear wheel ended up in a sand hole of close on 150mm deep. This made the trip up the ramp less successful, but does account for a little more flex than what is initially seen.
Gerrit mentions that there is way to little flex on the rear. Not much has changed that end, besides the 130mm lift blocks that have been added on the each end of the leaf pack, and then a set of Gabriel shocks, from Ians Patrol, has replaced the old Sani shocks while they were moved to new mounting points top and bottom so that they face toward each other instead of being on each side of the diff as it is on the Hardbody.
The leaf springs used up front, are standard Hardbody one tonner packs, with an added military wrap blade to carry the additional weight of the engine.
I have some things in mind for the front end, one of which will be an increase in Castor. Another being the addition of a Panhard rod, and then also a stabiliser. Shock mounts on the diff have been planned below the diff tubes since day one with the use of fleetrider shocks that will give me 375mm range from around 530mm up to 900mm.
The rear end is still a total unknown. The H260 Diff and probably 1,5 times the weight of the little diff that is presently in there. I expect the additional weight is going to change drop out considerably (or am I mistaken). I also wanted to employ revolver drop out shackles to assist articulation, but that’s not a definite yet as I may be running into problems in that the propshaft may not be able to handle the angles already after the nearly 7" lift.
So the question is, at the moment, is the front end too soft, or the rear too hard?
I'm I worried about too many things now when too much could still change by the time everything is complete, and that I should rather just wait until later to "fine tune" these little gremlins.
Keep in mind, this is still my daily drive, so the rubbish handling I have at the moment is somewhat of an issue. I am hoping that the big culprit of the bad handling, is the very small Castor I presently have, and that the increase to around 7 degrease is going to do a lot to fix this. It presently at around 1,5deg.
... Need to get this done before someone else uses it all up
