Front Drive Shaft Update

[acky]

Hi All, been reading watching for awhile.
Mine failed 24 Trailmaster, 17000k's Eibach lift (35mm) all done at Expedition HQ when the vehicle was new (i suspect pre-delivery, i bought it used)
managed to get a new one done under some deal worked out between ExpHQ, Ineos and the local dealer
this was approx 5000k's ago, no sign of failure as yet, i have done a few weekends mild to hard 4wding

I was advised when it was replaced that this wont happen again, i wont say by who but they hinted at a new rubber design.
Still makes me nervous though and i check regularly

I have a big trip coming up to the Vic High country at Christmas, im thinking about grabbing a jeep JL\JT Rzeppa joint as a spare
are these still the best option?

Seems so, with reservations re the fit on the splines. See post #519 in this thread

Everyone is conerntrating on the static driveline angle as the contributing factor to the CV failures and correctly so, but are there other issue that need to be considered and added into the equation like CV lubricant type, excessive heat transfer or operational powertrain movement under load or in certain driving scenarios also playing a part in the CV failure?
Placing a few temperature recording decals in critical areas may assist. This give a visual reference to service departments and owners a way of quickly checking for any impending issues.

Surely they selected high temp cv grease?

Yes, it will be a lithium soap based with mineral oil grease they use because it is the most cost effective CV grease to suit all CV applications on the production line.
The main factor for a CV is the extreme pressure (EP) additive required which is commonly molybdenum disulphide (moly) with the addition of graphite. Moly grease generally comes in 2 3 5% or more. Cv grease is around 3% any higher the balls in the cv will likely start skidding because molybdenum disulphide can act like a wheel chock if there is excessive amounts in roller elements of bearings.

I bought temp indicator paint just for this. But then I used my IR gun and found the temps are nowhere near what's needed to fail the boot.

We need to get the attention of Lynn Calder. Perhaps it’s time that the lot of us all comment on her LinkedIn posts. The last one only has 14 comments on it. We can certainly stand out and perhaps whoever manages her account for her will pass on that the owners are pissed off. Here is here account https://www.linkedin.com/in/lynn-calder-a6814b55?

Mark my words, someone is going to get hurt when one of these fail at 75 mph. My post in the ask Ineos section is marked as solved because someone asked her about this issue and she said that she would look into it. That isn’t solved. That is the answer a politician gives when they want to avoid the truth. No doubt the attorneys have told her not to comment.

I absolutely love this truck but Ineos needs to address this engineering flaw.

Definitely preferred it when it was attached rather than in the boot. Will pop by Chandlers in Horncastle for a chat before heading home. Will diagnose cause and report back.

Front and rear diffs also leaking AGAIN (photo from underneath inspection day before trip)

What’s it like to drive in CDL high with the front driveshaft removed?

What’s it like to drive in CDL high with the front driveshaft removed?

Sub optimal when pulling away or reversing - bit of a delay. At normal road speed I didnt notice much difference. Got a 5hr drive later so will know more then. Just want to get the dogs home in one piece.
