Front Drive Shaft Update

[Tazzieman]

Mine failed spectacularly in a molten ball of fire on the highway, and left no damage. That being said, if you went long enough for it to really fling around under neath, that could be bad.

My 1966 Mercedes W108 has a 30cm weld scar on the transmission tunnel, a reminder of the time the front propshaft rubber coupling gave way , I imagine at some speed, at some time in the past.

Hmmmm. Their capability statement suggests they're in the right engineering space to assist. Getting them to see the scale of a global opportunity would be key to getting their interest. IA should talk to them about an OEM solution.

Any of you sand gropers in the Perth area feel like a drive to Mundaring? Take some beers .

Would be very interesting for them to have a look at the Grenadier’s design, while also hearing their take on the current issue. This outfit look sharp.
Australia once was one of the few countries in the world that could manufacture every part of an automobile, sadly those days are gone.

Definitely worthwhile for a WA owner to pay them a visit.

The problem as always is the small market and low volume. Whilst it is likely they have the expertise to develop a solution, expecting a small business to invest the time and cost to develop something and amortize the outlay cost before making a profit is a big ask. Now if this was LC250 or LC300 or Ranger or Hilux that are all selling in volume in Australia that would make an investment decision easier.

If Dana Spicer (OEM of the Grenadier driveshafts) aren't already working on something with IA I really think our best chance is to lobby IA to get the problem acknowledged at the proper program level then guide them towards companies like Proformance to do an OEM solution with an Ineos warranty.
Proformance would be more receptive to a purchase order from IA for 00,000 parts, versus carrying the risk and cost themselves to do a retail part with no guaranteed ROI. It's also easier for them to deal with one customer for product support and warranty.

But you're right. A great place to start would be to show them the problem and test their interest.

I'd be concerned if it failed on the road that it would either flop around enough to damage the transmission or transfer case, or hit the ground, dig in and destroy the transfer case and/or the transmission, + + +

I don't see how it could go that bad unless you ran it so long that the bearings broke apart and fell out. Even then, due to the design there might not be enough play in the flex joint to allow the splined shaft to back all the way out.

That exactly what happens if the C-clip fails.

I think it's important to realize that the CV in the Grenadier is the exact same part found in Jeeps and many other vehicles. Jeeps have had the same problem we are having for the most part. These problems have been going on for what; a decade?

Nobody has solved the joint problem. They just change to a Cardan shaft and call it good. But Jeeps don't have the messed up drive line geometry issues we have. So that works just fine.

We are in a tight spot boys! It's a solvable problem I think but not likely as simple as you would hope.
