Front drive shaft broken

[Tom D]

Have we confirmed that the teraflex CV’s will fit on to the IG shaft? And the axle flanges?

 

[ECrider]

So question - presuming one DOESN’T do any lift, what size tires will fit without rubbing? And have we seen drive shaft failures when ONLY larger diameter tires were fitted, without a lift (other than the couple of stock failures)?

I'm a few martinis in so my thinking might not be spot on, I don't think by adding larger tyres you effect the drive line as simply raising the whole car as opposed to lift where moving parts away from the axles.

this is exactly my thinking as well. the geometry between the axle and the body stays the same.

I agree with you Tazzieman and I respect those that take a conservative approach to their IG. Personally, I've enjoyed modifying my IG but I accept the risk without whining. Plus, I live 20 minutes from a dealer and Amazon can deliver a Teraflex CV to me in two days.

So when I am in Austin, it was 1 day to get it, only in Durango does it take multiple days, I am sure in Moab you could get one in Day via Amazon.

@parb and @ECrider - exactly. The WHOLE geometry, I believe, stays intact - just up a bit. So no additional angle on the drive shaft. You can still pick up an inch of clearance that way without the drive shaft risk. If the extra clearance is really that important, probably the best solution. I think the martinis made you lucid and succinct, @ECrider

i have 33.5" tires on mine. i know several others who have that size tires on (1.5" larger than stock) without a problem, several who are much more hardcore offroader than i am.

So a 275/70/17 or what?

yes, the one for the Jeep JL Teraflex 1745000. I've got one coming in and have talked to another owner that has one installed and has ~500 miles on it with no issues.

I'm running a Mickey Thompson 255/85/r17 (34 x 10) on stock steel wheels and stock suspension without rub. I ran the IG from Lake city to American Basin last weekend without issue on this setup.

That’s fair enough if you’re prepared to take the financial risk. But I just don’t get it myself.

My recollection of the Ineos promotional videos and trips and photos before release is that they included many instances where the factory itself was using 35" tires, for example that big Africa trip they did. My understanding is that 35" tires will not fit without a lift. So I assume during those factory tests that Ineos had taller springs installed? Does anyone have any insight on that?

Are we looking at that as just an easily obtainable road-side repair part? From the looks, it seems that the Teraflex would be subject to the same failures as the stock unit? Or am I missing some reason why its design is better than stock?

There have been reported failures with the stock springs. I think there was at least one person earlier in this thread. I don't know if they had larger tires or not.

From the TeraFlex website:
"The TeraFlex JK: Rzeppa High-Angle Factory Replacement CV Joint Kit replaces a worn or damaged factory Rzeppa CV joint and driveshaft without resorting to an expensive aftermarket U-joint upgrade. Allows angles up to 15 degrees. The high-angle CV housing reduces boot failure associated with 3" or more lift. The included low-friction grease is engineered specifically for the high RPM needs of the JK Rzeppa CV joint and features high-viscosity surface bonding characteristics necessary to properly adhere the grease to all moving surfaces."

I believe this was a c clip failure, not a boot failure.

I think it was @Logsplitter - who was running stock suspension and tires? I can’t remember

That’s correct it was my vehicle. No mods bar some extra electrical sockets.

And did the issue end up being c clip? I can’t remember the details

The Ineos Kavango Safari vehicle is running 34” The Ineos guys were very secretive or just plain didn’t know what has been done to suspension or running gear when I asked at the Game Fair UK.
First two pictures are from the game fair and second two from Ineos dealer in Gabarone ,I think that one is on 35” tyres. My guess is they have spacers on the springs

Yes the C clip that failed.

the dirt box overland vid has Kenda 35 x 10.5 on a stock suspension. he says no rubbing.

No spacers on the springs . Word has it on this forum that you can’t run 35” without some sort of lift as they will rub.
