Try to find a low mileage 98 LSE, 98 Anniversary Edition, or any 99 D1.

I am partial to my LSE as it has been a great truck over the years. Showing its age and use now, but this picture always reminds me of "what was" a nice truck.

That is super clean! Are those DII flares?

Question for the DI guys. Normally on a Jeep I wouldn't worry much about buying one with 150k miles, but how long do the Disco's last? I'm look at 2 one has 127k the other 150k...

Same as a Jeep or much of anything else. 99% of that depends on how it was maintained.

Mine has 220k or so on it. The heads were a nightmare when I pulled them off to do gaskets a couple months ago (obviously leaking valve guide seals with baked oil everywhere). But the thing was still chugging along just fine. Now it continues to chug along without needing a gallon of coolant for every tank of fuel.

The flares on my truck are made of a rubber/foam material. I have no idea where someone bought them and I have never seen another set like them. They came on a 96 Disco I had for a short period, and I took them off and added them on my 98.

This pic was 4 years ago back when I babied my truck. No scratches, dents, or rust. The interior was perfect too. My son is much bigger now, and my truck is showing its use and abuse.

I bought a D1 with 133k for $2200, now at 146k. Did a little bit of work on it, but not a whole lot. My brother drives an XJ with 170kmi, and a D1 with unclear mileage, somewhere near 150k. They all leak oil at comparable rates.

210 on my daily driver, the wheeling rig has 240 but the engine is not the original.

if you follow the manual (maintain the coolant system, run premium only) they are very reliable vehicles. The problem now is finding a clean one that hasn't been ignored or fed 86 octane its whole life.


d1driver- those are factory d1 flares. My 95 had them.

03disco2 how did the centre diff "give out". They are not a viscous set up. Do you mean you had a shift problem to engage CDL or didn't lock it for whatever reason and relied purely on traction control? Cheers

I'm thinking he didn't actually have a CDL. I didnt think any 03's did unless it was installed later on by the owner.

I see - here all 03's (ie new lights D2a) have CDL (not just the internals, but the shift lever etc for it).

Cheers

PS. I have a 95 D1 auto and an 02 DII manual (stick) with the CDL retrofitted. I love both. The D1 is simpler to work on, but to be honest I prefer the D2, but there isnt much in it, and if I was stuck with only the D1 I would still be happy.

That explains why my 03 owners manual suggests that the diff lock is there, even though I don't have one.

I'm no D2 expert but I believe some '03's have a CDL equipped TC, just no linkage to enable it. Some people rig up a pull cable or turn the nipple with a wrench to lock it. Other '03's, I believe, don't have a CDL TC at all.
Anyone care to ellaborate on this?

This is the most arrogant group you have ever met? You must not know any pilots.

It may make your contact patch wider, but unless you're in deep sand or snow, the benefits are not so clear.

Last Sunday, however, I found a spot that I was able to drive through before with 25psi in tires that I was unable to do with 45 (dry granite).

The D2's that dont have the CDL shifter, but do have the internals (not all did have the internals) can be locked using the lug. I think years ago on this site there were people welding up pieces of rod and sockets etc to do it. The D2 has such a capable traction control, but it really is much better with both traction control and centre diff locked up.

As for airing down - it makes a massive difference in deep soft sand, especially towing a couple of tonns) - as said above it elongates the patch (bigger, but also the contact angle to the sand is reduced so it tends to roll more than dig in), but bear in mind that you get less clearance under the diffs (but if you start with at least 31's who cares).

Airing down off road on rocks etc is more about allowing the tyre to deform around rocks and logs to grip them better, which it does.

Cheers

PS. We dont see many Jeeps off road here compared to other makes. Here Jeep parts prices are out of control, and they are not known to be the last word in reliability, even to LR drivers...Also, I dont think I comprehend how in stock form the Jeep Grand Cherokee with live axles can have such poor wheel travel/articulation.
