D2 traction control VS CDL being locked

[proper4wd]

An even more interesting component to this argument is that you have not driven a Discovery with a CDL and without, back to back, on the same terrain so thus you really have no valid basis for making any argument.

The people who are advocating for CDL have in fact done this and do have a basis for an argument.

Case closed.

Do you even have a discovery? If you dont even own one are you really party to this discussion ? Apparently, the ten different times i have said that a cdl is better then traction control only discovery is not enough to sink in. I do have a valid basis in that I drive a discovery with Tc and i have vehicles with a cdl, how would I not be qualified to comment on the effectiveness of tc?. Is a cdl equipped discovery better then a Tc only discovery? sure, this has never been up for debate. Is tc better then a cdl equipped vehicle without tc? In certain cross axle situations yes. This debate has always been about if Tc effectiveness is enough for the overlanding use, and i feel it is.

Questioning my vehicle ownership will get you nowhere, I have a list of Land Rovers I have owned and professional certifications with the brand as long as train smoke. To add substance to this discussion could you please state:

Is this your first Land Rover? And how long have you owned it?

Like you said questioning vehicle ownership will get you nowhere. But those are the kind of questions you get when you make a statement and then declare case closed, as if you had just provided some kind of unknown life altering information that only you had been privy to. Based on your response you are much older then me to have been able to acquire such a lengthy list of certifications and vehicles ownership. My experience is much more limited to agriculture use and getting about every type of vehicle with wheels stuck and the following extraction. As well as trail riding in the hills of eastern ky. Not as good as your certifications but, we have to work with we have.

The point I have been trying to make that you clearly will never get is that just because TC will get YOU 90% of where you need to go dosent mean it will be suitable to get anyone else to their 90%.

 

[BirchHill]

Dont forget the way your vehicle is set up wont get some people to their 90% as well. And thats always going to be the case no matter what modifications you do there is always some one else who does something more extreme.

I know I get that. I'm not the one who said this....

"It really comes down to what you actually do with the truck vs what you think you do. I would say 90% of the places people actually take there discoveries, the TC system is more then capable of handling. If you really know how to utilize the system and drive it will go anywhere you want it to."

And this....

"So, now the axle twisters are rigged in some land rover conspiracy to make their TC look better? I think the traction control is adequate for 90% of what people subject there vehicle to. Sure a cdl is better so where do you stop with that line of thought?"

 

[BirchHill]

Here in lies the difference. The 90% I refer to is the discoveries out there and what their owners do with them. This is not the same as saying 90% of what every discovery owner does with their vehicle as a small percentage of owners like you do very extreme things with their vehicles.

This spring when it warms up I need to drop the transfer case to change a leaking input seal and I got a guy who offered me the locking snout and linkage from a d1 for $175 So, why I have it out on the bench I might as well change the snout. This would be strictly for scientific reasons to prove the cdl to be an unnecessary item. So will the locking snout from a D1 bolt up to the D2 case? I have read that it will but, the linkage will need a little love to make it work?

disco 2 for two years

I put on a d1 cdl lever

having both systems is better than traction control alone- locking the center diff helps alot.

locking the front rear power distribution


The d1 linkage is a direct bolt in

You can do it from inside the car- after fighting the gear stick-


I replaced the plate with self tappers rather than rivets

which was a god send when the linkage folded on the LR rally in Moab

drove back to GJ- wife showered etc I removed the linkage welded it back up
and was back to Moab a few hours later

from inside the car its a bit fiddly- some screws and bolts are dificult to get to

good excuse for a little set of those little folding ratcheting spanners

If you have access to a welder maybe weld the little sheet metal bent U- togther and add some support on the exterior- i used a couple of bent nails

The gear stick lock out solonoid can be removed while you have things apart

 

[BirchHill]

Welding is no problem, how about swapping the locking snout from the D1 transfer case to My D2 case?

Two other things to throw into the mix that haven't been brought up yet.

The first is that if the CDL is locked the hand brake works both front and rear axles versus just the rear. Better for parking on steep/loose surfaces. I suppose it is generally easy enough to avoid these parking situations but sometimes you must for one reason or another.

The second is recovering from a failed hill climb. I experienced a somewhat scary failed hill climb in our DII before I installed the CDL linkage. I ended up with the truck perpendicular to the slope leaning on a tree. Backing down a steep/loose hill unweights the front wheels and you loose steering control because the brakes lock up the front end very easily. The same experience with the CDL locked keeps the front wheels turning the same speed as the rears and you can maintain more control steering your way down the hill. After backing down the hill, I got under the truck with a 10mm wrench, locked the CDL and gave it another go. I didn't make it up, but the way down was uneventful. Shortly after is when I installed the CDL linkage.

You can get pretty far without the CDL and I drove it that way for years. But hooking it up really should be the first mod to a DII in my opinion for anyone driving beyond a "camry" rated dirt road. The failed hill climb is what convinced me to spend the $150 for the used DI linkage - it was a serious safety issue for me that day.

This is one of the better videos I have found of TC ONLY performance. Its in french but, it translates to without CDL

Haha It might still get up.
