What should I upgrade on my MY15 D90 to future proof it ?

[simonfish]

I love my MY15 D90, it has never had a problem (65k on the clock, so not a lot), but as I am looking to keep it for the long term, and do some touring, etc. I am looking at what I should be upgrading or replacing now, rather than wait for something to fail while on a trip.

I am having a LOF MT82 output shaft fitted soon (I have a bit of drive train slop), as I understand the output shaft can fail at inconvenient times.
What else should I be looking at, as preventative maintenance ?

I was reading that the intercooler can fail, so is this something I should replace now ?

Anything else ?

At 65k I’d say not much.

I’m at 120k on my MY16 now and the only thing I’ve had fail was the intercooler at about 90k. The clutch slave cylinder started leaking at about 110k, but I replaced that, along with the clutch, before it failed.

I think the intercooler is worth doing - replace it with a BAS. You might replace the intercooler hoses with silicone ones while you are in there, but really there’s nothing wrong with standard ones. If you do, use quality ones such as BAS or Allisport. I replaced mine really because the elbow is such a pain I didn’t want to deal with it on the road.

The clutch is worth considering as the slave cylinder is a gearbox out job, but I think at 65k its too early to worry about.

I’ve just fitted ATBs to the rear and centre diffs, which got rid of all my driveline slop. I also added an Aschroft adapter shaft while the transfer case was out but didn’t need to. My original adapter shaft was lubricated at the factory and was perfect at 110k.

If you are going to start using it for touring you may want to consider replacing the shocks, if you haven’t already. The OE shocks are pretty good but a set of Bilsteins or Konis are an improvement.

The only other minor thing I can think of is the rear brake shields have a habit of cracking. Mine did so I added some Nugget Stiffies.

Really the best thing you can do is just keep on top of the maintenance. Get under it regularly. Any thing that looks worn or is leaking replace it before it becomes a problem - you know, just the obvious stuff that you probably do already.

Cheers,
Jon

You're on the right track with the output shaft.

For the other items, you can opt to wait until they fail and upgrade accordingly. The trucks are pretty resilient unless you have no mechanical sympathy.

For some insurance, you can get the additional support brackets for the front axle. While your truck may not be affected by the welding on the front axle anymore, you never know plus, it's cheap insurance.

If you have a two pin rather than four pin front diff, you can opt to install the four pin version OR you can upgrade all three diffs to Ashcroft ATBs!

You can also switch out the rear drive members and CVs for the heavy duty one piece types (also available from LOF, and no, I'm not affiliated with them, just a happy customer). Then you can opt to upgrade the front CVs and drive members to the heavy duty Ashcroft ones.

For the rear dampeners, you can get the Gwyn Lewis pin to pin mount.

Fuel cooler guard or in your case, the fuel line guard to protect the line when it goes along the front end of the chassis.

When the time comes, you can switch out the bushes with SuperPro ones.

Upgrade the rear A-Frame ball joint with an extended range, greasable, heavy duty one from Gwyn Lewis.

Upgrade your air system with the Nugget Stuff sealed air system kit.

This is what comes to mind right now thus far

Oh, get the IIDTool BT from either Pete Bell or GAP Diagnostics. Worth it!

+1 for the nugget stuff stiffies, the disc guards can fall off and take out the ABS sensors or their wires usually when its most inconvenient, a cheap and easy fix. There was nothing wrong with my turbo hose except that by the time you get it out it's easier to put a new one back in. If you are doing the intercooler as a preventative measure then I'd be tempted to leave the hoses if the upgraded wire wound one has been fitted with the support bracket on the alternator.

I would get the extended front seat runners, a gas strut for closing the rear door and a spare wheel carrier to take the weight of the spare off the rear door, if you haven't already.
I would also fit Airbag Man rear air bags for extra support.
Silicone hoses are the way to go.
Plus bulbs in the headlights.

Want to future proof it? Easy…

Park it up, in a garage, and treat it with kid gloves.

We’ve just been offered $90k for ours.

[simonfish]

Some great advise here, thanks guys.

If i went a BAS tune (140bhp) and intercooler route, who would people recommend I talk to in Brisbane/Gold Coast area ?

Do you really mean future-proof?

Defender was about 15 years out of date already by 2015… so future-proofing is somewhat paradoxical. So many issues on these cars are fundamental to the techniques/ technologies employed, and are essentially unfixable/ part of the charm.

My 2c. - If you live in a big city, you’ll be fine to deal with mechanical issues as they arise. Though the output shaft is a great pre-emptive item to change out which is likely to improve the ride/clunks. My experience has shown mechanical problems usually aren’t major, to do with engines and gearboxes, that may stop you, but irritating things to do with fitments, interiors, accessories etc. Door central-lockers, speakers not working, rattles, bangs, dents, etc.

Corrosion and leaks are a problem… so maybe that’s one thing area to look into if a shiny/ garaged car is your goal (no judgement - many shiny city cars out there commanding high prices).

[Samblers]

I should add (for the sake of variety of opinion) that my idea of future-proofing has nothing to do with adding more power or changing out factory drivetrain components. In this respect LR did a good job, and I’ve never thought that the car lacked power. I like the ride and find the seats are comfortable for road trips. The a/c works fine too.

My future-proofed defender would have:

Auto gbox
Cruise control
Well-built doors
Apple Car Play
Split rear door
Reverse sensor
Central locking that works from further than 50cm away
No dust/water leaks
Proper body/chassis corrosion protection
A bit bigger fuel tank

These features would assure my continued ownership and enjoyment into the future.

Apart from the rear door, sounds like an L663!!

My idea of 'future proof' is to drive it as and when I want, in the city (I live in Brisbane) and for weekends away (Fraser Island, Granite Belt, etc) without too many problems (ie: with mechanical failures that I can rectify now with preventative maintenance or changing our parts that are known to fail) , and in the future (5+ years) look to convert it to a full electric vehicle.

Thank you for those that have offered advise on how to rectify known issues.

[loanrangie]

Lol, future proof a 70yo design - better start from ground up [emoji16].

[simonfish]

hi mate, not sure if you are just teasing, or if you are a ******.

i (like many on this forum) like and enjoy our Defenders, if you don't, then maybe go some where else.

[Samblers]

Relax.

It’s possible to admire and enjoy something that isn’t perfect… that is why we are all here.

A bit too serious reply to a tongue in cheek comment by another AULRO member.
What loanrangie said is valid and his comment really was just beating me to it.

*A Defender is a antiquated hodge bodge of a build and designed vehicle.
*Over the years they (JLR) have cobbled together bits and pieces of parts from other manufacturers mostly dependant on who owned Land Rover at the time.
*Before you go have a sook and cry, I own 4 Defenders and my work focus is repairing and maintaining Defenders for a living.

*Saying all that, Defender 2007 - 2016 is the best model that was produced (if for nothing else, you have a heater and a/c that actually works (most of the time)).
*Have a search for some of my other posts and you will find there is a good long list of "future proof" items you may wish to get done or rather may well fail at some point.

"Future Proof" I will be tempted to use that term now [tonguewink][tonguewink]

[shack]

I am not at all concerned about future proofing any of the Defenders here.

Water proofing however is proving to be "taxing".

[skidrov]

One could argue they future-proofed it 70 years ago, but in 2016, the future finally caught up with it and over-ran it... [emoji854]

Since you're already going the BAS Tune route, why not coordinate with Pete himself? You can also get the EGR de-activation and immobilizer delete (unless Defender theft is rampant there) to further help your vehicle.

Since I mentioned the EGR de-activation, get a ProVent catch can to keep your engine healthy.
