looking for some info on the rear diff lock? in doing research on available options i found that theres a rear tow package as an option. it says in the package that it comes with a variable locking rear diff. so my question is, is there no locking rear diff without the tow package? or am i missing something? trying to ask a salesman a technical question(or non tech for that matter) is almost comical and I'm about to pull the trigger here so some help would be much appreciated. thanks fellas!

 

is there no locking rear diff without the tow package? I believe so.

Im not sure about this, but i was under the impression that rovers with the terrain response system do not have locking front or rear diffs.

 

I bought a 2012 RR SC last October and had the same question about the electronic rear diff. I talked to a dealership and there was only one type of rear diff fitted on the 2012 RR SC: The electronic one. It makes no difference whether it has tow package or not, they all have the same diff.

There is a choice of rear diff if not an SC model, so that may be where the confusion comes from.

One other note: Mine came with the tow package, but not the full-sized spare, although the full-sized spare was an option apparently. So I picked up a remanufactured rim for $250 and a new TPMS for $50, so worked out ok for me.

Hope this helps for anyone else looking at a 2012 RR SC.

 

thanks for the input, but thats incorrect. the only way to get a electronic locking rear diff on this model was to have the tow package option added. not quite sure what you mean exactly when you say they all the same diff, an electronic one. they all do of course have a differential in the rear end, but only the tow package offers it with an electronic locking rear differential.

asking the dealers about that was laughable to say the least. i spoke with atleast 20 dealers and salesmen and not a single one of them knew what i was even talking about. most of them didn't even know what options were available for the car, such as the most basic package like the silver pack. let alone the difference of coming with, or even what a locking rear diff was.

 

And you're the expert after speaking with the dealer yahoos?

at what point did i say i became an expert after speaking with the dealers? i had to figure it out despite them. i researched the packages and how to find out how you get the locking rear diff. thanks for chiming in though man, glad youre paying attention.

 

Well Cobra, I am not going to make the mistake of stating something without any proof to back it up, although you may feel "Speaking with at least 20 dealers and salesmen" may be proof enough. I agree with you about not believing Sales People, but you did talk to them, which is interesting. One further point of clarification: The Silver Package was not an option in 2012 until October 2012, it was fitted as standard for MY2012 until October when it became an Delete Option.
"All initial 12 MY HSE LUX and Supercharged orders will be built with the Silver Pack. From October Order Call both models can be ordered with Silver Pack as a delete option."

Maybe limit the absolute statements in future and qualify everything with "As far as I am aware".



For the folks reading this thread to get insight into the Rear Axle on a 2012 Supercharged, this is what I can state, as it actually happened:
I contacted the Landrover Service department in North Scottsdale and asked them to provide a printout of the features included with the specific car I was buying. I provided the VIN. I also asked them specifically to determine whether it had the Variable Electronic Rear Differential or the standard unit diff fitted to the HSE. The response I received from them after they had researched was that the RR SC 2012 was only fitted with one type of Rear Differential for that year. (I am generally skeptical of dealers, but in this case they did research and provide an answer rather than shooting from the hip and I commend them for that)

Additionally, if you look at the options 2012 RR you find:
Reduced section spare introduced as a standard feature
• Towing Preparation introduced as an option on HSE, HSE w/LUX and Supercharged and consists of:
o Towing cross member including receiver tube
o Trailer towing electrics
o Variable rear differential lock
o Full size spare
o Tow on HSE, HSE LUX includes Adaptive Dynamics ( Adaptive Dynamics standard on S/C)

However, the Towing cross member was standard on the 2012 SC, but no electrics and no Full Sized spare and I presume that the Variable rear differential lock was standard.
Note that Adaptive Dynamics is standard on SC

I also found this reference 2012 Land Rover Range Rover Specifications, Pricing, Photos - Motor Trend
That states:
Electronically Variable Locking Rear Differential
CONTAINED IN: [ADF] Adaptive Dynamics Suspension; [TOW] Towing Prep Pkg

So: In conclusion, as the 2012 RR SC comes standard with Adaptive Dynamics Suspension (which includes the Variable Locking Rear Differential), then I deduce from that that ALL 2012 RR SC's come standard with the Variable Locking Rear Differential, which ties out to the Dealer comment that only one type of differential was available for the 2012 RR SC. (Dang, did I just prove that the dealer got it right? :-))

If anyone has any actual facts that disprove my analysis and findings, please post them as I would not want anyone misled if my analysis turns out to be wrong. (I don't claim to be omnipotent!)

 

thanks for all the extra info, but honestly its a bit muddy and confusing. the info you just gave is contradicting itself. if I'm understanding, youre saying that the tow prep was an option for all models. then below that you mention that the 2012 SC came standard with the towing crossmember? 2012 SC 100% did not come standard with a rear tow crossmember.

 

Suggest you try to find a LR tech specialist or good LR technician with experience on that diff to ask. You may also be able to pay a small sum for access to the LR technical manuals available for the vehicle and read them yourself. Marketing BS and sales folks lack much of the technical info you seem to be looking for.
