The 2016 Base had a Limited Slip Differential, but for some reason my 2017 Base does not. Sad!!

Can I fit a LSD to my car, and any idea how expensive?

Thanks!

 

I don't think any base has had an LSD, either standard or as an option.

There are a few threads here about wanting to change or install an LSD - I don't think they went forward.

 

Its possible that I was misinformed about prior Base models and LSD. Sorry.

I did a Search for threads - maybe I just missed them or had the wrong search parameters. But my right foot tells me that this one doesn't have LSD!

 

Problem is that the base V6 has a different diff ratio to the V6S, so you can't just bolt in the V6S diff, it will throw a heap of codes and go into restricted performance because of the incorrect ratio.

Easiest solution is trade in the car for a V6S.

 

So Jag never made a F-Type LSD with my diff ratio? That's a drag.

Thanks for the info. Guess I'll leave my right foot in it's current calibration ;-)

 

I am planning on upgrading my diff. To a quaife differential. There is a guy in England that says it is very likely he can modify it to fit.I am.pretty sure we have the same gearing differential ( I am in a '15 XF 3.0L).

 

I drive my car somewhat hard and also track it, you really don't need an LSD at all especially with the stock power output! I'm running 450 and still don't see the need! Just invest in some Pilot Super Sports!

 

Tires are probably most of the problem - my car came with Conti's, and I've been trying to burn them off, and they show very little wear in 7k miles (and my wife is too cheap to throw them away just so I can drive the car harder ;-). The reason I want the LSD is to get the car to track straighter under hard acceleration. Currently, it kicks out the rear just about every time I floor it. And I have a 90 degree corner that I must hurry on - merging into heavy 70 mph traffic on a two lane road - and I like to be on the throttle before the car gets straight. I'm OK in TracDSC, but the rear moves around a lot...

If anyone comes up with a solution, please let me know!

Under the circumstances you mention, an open diff will kick out less than an LSD when accelerating out of a side street. With the open diff, one of the rear wheels will not be spinning giving you better lateral stability. An LSD will spin both tires causing a larger fishtail out of the side street.

 

I would be interested in this if price is reasonable, etc. Could you PM me details please? Maybe we can get a group buy organised.

 

What mods have you made to the car?

 

Different ratio in your V6 XF and in the base V6 F-Type...

 

Would it not be possible to mod it separately for the XF and F-Type a.k.a. mod 1 differential for the XF's final ratio and mod 2 for the base F-Type's final ratio? Or is that not possible (I really have no idea)?

 

I got in touch with this guy through a few other people who recommended him. Here is his info:

I explained what I was trying to do along with the mods on my car and he seemed confident that a Quaife LSD can be made to work. We have not discussed cost yet, but figure a Quaife to be about $1200 to $1500, then add his charge to modifying it. Since I just spent quite a bit on a custom spray kit, it would be nice if there is a group buy that may lower the final cost. Please keep me in the loop if a group buy is in the works

 

The OEM who makes these diffs in the late model Jags is the UK company GKN Driveline.

GKN appears to have zero activity in the aftermarket, they only do OEM business. It also would not surprise me if their supply contract to JLR also included a clause about "no aftermarket support or upgrades of JLR product" as that is their thing these days.

But... obviously GKN does produce limited-slip differentials (i.e. what's in the V6S) and they also supply to other vehicle manufacturers as well.

So far I found references to GKN supplying diffs to most of the major manufacturers in one way or another, but I have not found any pictures of a diff that looks the same as the ones in the Jags.

It seems likely to me, that there will be an LSD centre that matches the diffs in the Jags, but to my knowledge, nobody has opened up one of the Jag diffs and taken any photos or measurements to cross check them.

EDIT

I think the fastest solution will be to buy a V6S diff, and a V6 diff, pull them both apart and swap the centres over. If you get lucky with diffs from wrecked cars at a good price and have a friend who can do the hands on work for beers, it'll be reasonably economical...

 

lol...finding the friend that can do the work is likely to be the bottleneck to that plan.

Whats your schedule looking like Cambo....lol....

I consider myself competent when it comes to working on cars...mostly if I am able to find some sort of guidance via online forums and service manuals....breaking apart a differential and swapping out internals is not something I personally would consider doing, primarily because I have only experience in robotic versions of planetary gearing, which is nowhere near as involved as what is in a LSD that needs to handle massive amounts of torque.

 

+1. Properly shimming a diff setup is a real art form.

 

Thanks, all. Sounds like entirely too much of a tricky problem to get a proper fix, and I'm not going to get a S just for the LSD and 40 hp. Tires will help when I can finally burn these damn Conti's off...

I guess that I'll just continue to drive around it. Just hate these First World problems...

 

I spoke with Jaguar of Sacramento and their tech told me there are aftermarket LSD's you can purchase for the base model. The base has a mechanical LSD so he said if you call a differential shop they might be able to make one, or know of one you can use.
