3.9 V8 petrol versus TD5

**PhilipA** · 31st December 2022, 08:01 AM

The D2 suspension is completely different to the D1.

BMW fitted neutral radius steering which made them much more stable on the highway but introduced ball joints rather than swivels. the ball joints can fail if neglected like the boots cracking and nobody adding grease. The rear has a Watts linkage instead of the centre ball joint and longer leading arms.

Mine are now at 236KK with gone boots but greased every oil change with bodged boots made up from rubber and spit. AFAI can tell there is no movement and they are fine.

Couple of differences with V8 and TD5. With a diesel you largely cannot increase speed greatly uphill as you cannot really kick down like a V8 and go. BUT the TD5 is a much better tow vehicle as you can maintain speed up hills where the V8 will die in the bum as the TD5 has lots of torque at 2000Rpm wheras the V8 does not. My RRC 3.9 was well tuned with heads, chip, dyno tune, and at the end Thor manifold for torque but still could not match my TD5 for torque.
The Traction control on D2s is great and only second best to lockers or torque biassing diffs if the brakes are maintained and have soft pads.
Make sure you get one with a centre diff lock so unless you are handy avoid 2002 . All D2As have centre diff lock and most importantly the linkages.

YES. Mine is a MY00 (built late 99) and had the CDL lever delete. It has a dealer fitted lever package which in my case means two levers, which is confusing at first. The one I had as a parts car had an AMV jobbie with a switch and a window motor to activate it. There are other versions.

Phillip says the TC is great, and it is, but it's not the substitute for a CDL that LR thought it would be.

Have you got a pic of the 2 lever arrangement? I'd be interested to see it..

I can sure get one from inside.

Here you go. Not too unprofessional. Left for High/Low, right for CDL. The knob on the right tells lies though; simple fore and aft action.

Guess it could use a clean

Thanks for that, that's an interesting setup, so that was the "genuine" answer?

Well, it was Ritter's answer in the case of my car, I guess. I'd have to find the books, which would be hard atm, but Ritters did, or organized, some mods. Sunroof, ARB bar, Safari snorkel, brake controller. a hardwired chip for the MSB, and a CDL lever kit.

Typical on-sell stuff, except for the chip.

Have to get under the thing in the next few days. I'll try and get a pic of how it connects if you like.

Got one of these in my shed which I got about 4 years ago, then an ashcroft one came up cheap, very cheap and went that way and there were tutorials online.

It seemed more complicated but now i see that the advantage was it would fit without having to cut the undertray of the console.

Still come across people wanting to fit the CDL levers. You might get a bob or two for that. Last time I looked the Ashcroft ones weren't cheap at all, so you were lucky. I always thought the one in mine was unnecessarily complicated. Why wouldn't a D1 lever work?

The D1 lever does work. Prior to the D2a coming out, thats what people were fitting to reactivate the CDL. The D2a levers being cable operated however wasn't bringing into the cabin all of the NVH that the D1 lever was, so shortly after the D2a was released people started using them and it wasn't too long after that you virtually didn't hear of D1 CDL lever fitment to D2s anymore.

The D2a lever also pretty much canned all of the other aftermarket CDL solutions manufactured by LR specialists. Davis Performance had one which locked CDL when in low range. AMV I think had a electric version made with a windscreen wiper motor to activate CDL. I hadn't seen your one before with the 2x forward/backward levers. Another mob had a shaft come through the centre console that was connected to the CDL spigot, and you twisted the lever to activate CDL. I'd also been sent a pneumatic ram operated one which I really liked, it probably just used an airlocker switch. Some also just got under the Disco with a 10mm spanner too.
