Bemble commented to me earlier on another forum about my diff change idea. He did not yet comment on this topic on this forum or on the other forum where I posted the identical issues. In the attached photo I see two o-rings. But there might...

That would be awesome if you mean Langley near to Stevenage? And not the CIA headquarters in America. The iCarSoft does not work on the P38. Your CR-Max, if it is the V3 with the latest software, will be identical to the LR V3. I bought the LR...

If I am driving at 70 mph in fifth gear and then I forced my gearbox to go into third gear, I will theoretically use the same fuel but I am putting more stress on the components by running them at a faster speed. I wish to God I never mentioned...

I am a Pepsi Max man...

Most people with the GAP tool will be vin locked to their vehicle, you can add extra vins for 60 odd quid each.

Oh god, of course. I read that last year when I was thinking to buy one. Hmmm. That ruins my plan. I guess the V3 iCarSoft for £160 and try to sell my V2 iCarSoft to someone, that does not write data to the car.

Before I bought my OBD reader I looked into this but I do not have a Windows laptop. I saw some cables with laptop on eBay but they were all for the later model cars, not for my 2002 L322. I bought the V2 iCarSoft because the company said that...

The whole point of coming here was to not find out through spending time and money on something that might be pointless.

iPhone but I turned them off years ago and I do not know (or want to know) how to turn them back on.

I think this image is it, for the BMW equivalent M62, showing a straight line due to vanos? I normally do not get over 1,500 RPM in my daily driving, so I am barely using the power of the car, but I feel no need to do that. Given that the...

Very good point. I do not know how to do emoji but if I did I would do the same face. I am now wondering how to find the torque curve of the 4.4 petrol L322 engine...

I was not concerned but if I changed them for newer diffs without rust that adds a small extra benefit to making the change. I have no plans to change the diffs due to the rust. My aim was to reduce RPM during steady driving on motorways /...

I can manually select 5th gear if needed if it does not automatically change up.

Thanks. EDIT: I found out how to put myself on the map to be available to help others.

Wow what an amazing resource! Unfortunately the people near to me that have diagnostic equipment all mention that they have a generic OBD reader that can only read information from the car not to write information back to the car. I need the...

Go to main forum list, and start there. The LZIR thread has a link to the map.

My diffs are incredibly rusty. I mentioned that they are so rusty that the MOT guy mentioned them but I already was aware that they are really rusty. I am talking about flakes of metal falling off them when you touch them slightly, so badly that...

I am not sure on the physics of this but I think the engine in my 2002 L322 will do ok given that it is built to tow, and I will have myself, my dogs and not much else in the car. My main motivation is that there are long periods of steady...

I am sorry that I mentioned the fuel aspect, only to stop people saying that it was a waste of money. My main reason is to run the engine at a lower RPM on a long trip. Just to put a little bit less stress on a 23-year-old engine.

Just the many diffs that are available on eBay and from wreckers of L322s in the UK. As RRPhil mentioned elsewhere the 2.76 diff is from the 8 speed diesel L322 so they will all be relatively new diffs compared to mine from 2002 with 153k miles...

Thank you for this important information.

Changing the diffs will not affect the speedo as that is driven from the wheels via the ABS sensors.

I cannot seem to find this section of the website but I appreciate you suggesting it.

I'm not going to waste time answering your questions when you can look it up yourself if it actually matters to you. You can just Google L322 diff ratios or look for a second hand L322 diff with the ratios that I have mentioned and see that they...

The SC has an 8 speed gearbox. I think the 2.76 diffs are from a diesel L322. The oil was dark when I changed it but I have no reason to suspect that the internal diffs are not OK. But on my latest MOT they noted the rust on the diffs as a...

I am not the first person to modify a Range Rover to better suit their specific needs. In fact Range Rover changed from a five speed gearbox to a six speed gearbox to an eight speed gearbox. I don't see any problem with improving something...

The guy that I bought the car off had died two years earlier and his widow sold it to me and she was German and barely spoke English. I have no idea what it was used for. I noticed many strange things with the car such as the rear right height...

I'm not dropping revs or running at higher revs. With my current differentials at 70mph on the motorway it runs at about 1,300 RPM. With the 2.76 diffs it will run at maybe 1,100 RPM. So a lower RPM for long trips. I would not put more stress on...

If I cannot find out the details of the o-ring (if that is the correct solution) then I will probably have to use the sealant. As it is not leaking massively at the moment I can give it some time to see if someone has the answer. I will also...
