Order a spare rotoflex coupler from AB and carry it with you so that you have it if or when your current coupler breaks. Make sure you inspect the coupler for cracks and other damage every time you get under the truck to grease it

 

The rotoflex is a strong as a u-joint, more flexiable and will give you a months warning before it fails, a u-joint won't.
Mine has made it thru the Sierras, Death Valley, the Rubican and a lot of Colorado and Moab, something to think about when you put them down.

 

I'm new to Discos(three days)

I'm running double cardin shafts front and rear on my defender and I cut the rear sway bar and welded a bigger section of pipe to it so that the two pieces slide together and apart held together with a big lock pin. I'm not running a front sway bar.

Maybe some of this can spin over to the disco. I have yet to think about mods and may not even mod it.

Have you checked with great basin rovers?
They make nice stuff and have iliminated the spacer that was needed before on the defender.

 

maybe they are stronger than they look, when I look at them all I see is a BMW ride control component that does not belong on a serious off-road vehicle. Do D90s and D110s use them also? The rubicon can be ran by a stock jeep, but if your rotoflex has survived lions back and slick rock at moab then I own rotoflexes an apology.

 

no they don't

Great basin makes nice stuff for both trucks though.

 

If you buy a roto don't keep it as a spare. Install the new one and keep the used one as a spare. It's not hard to do, but it's better to change it in the garage than on the trail when you're having fun with your buddies.

 

Just food for thought, our trucks put out a weak 188 horse power with little torque, some BMW's, Audi's Mercedes and others put out upwards of 400 plus horse power with torque we can only dream about. That being the case, why are they using a piece of rubber to transfer the power to the ground?
