Hi Everyone,

I am in search of an L320 (preferably Gen1 '06-'09) with the optional rear locking diff, and am in need of sage wisdom and advice on how to determine if a particular one has it. I've search the internets up on side and down the other, used Topix, and have put in a lot of time on my hands and knees with my camera attempting to determine whether or not a particular one has it or not, alas to no avail on clarifying their existence on L320's in general. Below are my notes:
1. Word on the street is that all Supercharged models came with the rear locker standard.
2. I looked up photos of parted out rear diffs both with, and without the e-locker and there is a distinct motor attached to the diffs with it included. You can't miss it.
3. However every supercharged Gen1 I have crawled under to photograph has had no such motor attached.
4. In addition, every supercharged VIN I have checked in TOPIX for Gen1.5 ('10-'13) has showed "rear axle open diff" on the spec sheet.

Am I out of luck? Are no L320's equipped and it was a big lie about the SC models? Shop techs and dealers insist all supercharged sports had them standard, but I can't find any evidence that this is the case. I really don't want to go the Discovery 3/4-LR3/4 route as it's simply more physical vehicle than I want or need, but there seems to be evidence that rear lockers do exist on Sports and if I can find something almost mechanically identical and smaller than a Discovery, that's the route I'd like to go.

Any and all help is appreciated, thanks!

 

The quick answer is, No, you weren't lied to.

I dont have all the details about what came equipped with them, but, I currently own a 2008 RR SC Full size and it has the rear locking diff on it. I am not entirely sure how the RR without the rear locking diff look, but, I think the easiest way to see if it is equipped is to go into the 4x4 menu on the dash screen and put the vehicle in any driving mode other than freeway, it should show a little padlock symbol over the read axle and shows if it is locked or unlocked.

I hope this makes sense, if not, I can take some photos for you tomorrow.

 

It was an option on the L320, and with the chassis being near identical to the LR3/4, I suspect you can identify the option visually the same way you are able to on the LR3/4 (via the driver's side wheel well, IIRC).

 

I've been checking to see if my 'new' LR3 has the locking rear diff. I found that mine does it. You can find out if you have it. Go to: www.vindecoderz.com and even there it's not easy. None of the other vin check websites I tried would give this very detailed level of equipment on a specific vehicle. Everything on the vehicle is rather run together so it's a bit labor intensive. But almost at the end I found what I was looking for and will try to paste it here... as an example. Hope this helps.
