Fuel Consumption for D4 with Trailer

My D2 was amazing compared to the D4, constant low 10s and towing the camper 12 to 13s fully loaded and really never changed whether I was offroad or onroad, it had a chip, and all the gear on it, bigger tyres roof racks and so on, the D4 on the other hand has all the gear but no chip and it really goes up once you're offroad and not by a little either, I've seen it up as high as 35l/100k and it sent the average for that tank up to 19l/100k on a past flinders trip when we went to the SA Land Rover Show, we did a little trip out to Nuccaleena and did the PAR back to Chambers Gorge towing the camper, it was after that trip we had the gearbox fixed.

Since the gearbox has been rebuilt the economy has improved quite a bit, so I'm thinking it may have had a lot to do with it's high economy, I have a feeling this may have been our D4s high economy issue since we purchaced it, because it's always had really bad economy since new and now it's not too bad, we might document the economy this Xmas and see how it compares from previous High Country trips.

And it's much better than my D2 or Defender were...

Looking at Redbacks post,maybe mine needs a gearbox rebuild

Mine didn't get any better with the upgrade,

But keep in mind all my vehicles don't tow,but are heavily loaded at times.

Hi, Scott. I just got a Mitch Hitch from a forum member. I tried to install it yesterday but taper lock was difficult to fit in the recovery eye. I noticed some try to grinder it and I hesitate to do that, would it reduce the stress level of recovery eye? I am think of cut the crush tube slot to make bigger gap, but also depends on how much room for male crush tube to expand. Any thoughts?

Cheers

You do need to remove the imperfections in the casting of the recovery eye. Being cast, and because you are only removing a relatively small amount, it does not affect the integrity of the eye.

I bought a dremel tool to do that job as it has a right angle head to access the eye. Have the used the dremel on numerous other jobs since too.

Exactly what I did too. Very handy bit of kit the Dremmel.

Gary, the grinding required removes almost zero metal from the eye just to create a smoother surface. The bush is still a tight fit even then and a few taps with a small hammer were required on mine to get it in fully. It requires a little fiddling to get both halves of the bush inserted and central due to the tight fit. Took me a few attempts.

I would not cut the bush in any way.

I must have got lucky when I installed my mitch hitch - no grinding or anything to the top eye, bush went straight in

**LRD414** · 18th December 2016, 09:27 AM

Was yours 2nd hand Shane? Could have been previous owner or just lucky with the casting.

It was second hand

It seems that I need to top up my handy man tool box. thanks. How do your guys go with the recovery points? I know you can put in a tongue with recover point.
