I do not need to fit the new diff to be able to determine that it will fit. I can do that with my eyes and with measuring devices such as rulers. Then when I can see that it will fit I can order the other one, and then I can fit both of them on the same day at the same time. It is this kind...

I posted an attachment that told you where the 2.76 diffs come from, and the rest of what it said had nothing to do with my answer to your question, but you thought that it did? That was an answer from Google and had nothing to do with what I plan to do. You kept going on and on about where...

I agree with everything that you have said here, it is just that I am not worried about wear and tear on anything other than the engine due to running a higher RPM. I am not concerned about the oil pressure because the engine will be running at an RPM that it is designed to run at. I am not...

I would only buy one diff at first to see if it fits, but I would definitely not drive around with two differentials with different ratios. But given the information that all of the L322 have the same part numbers for the drivetrain and the same subframe I will probably buy two diffs at the...

Actually my question was if it was a crazy idea, not if anyone had done it. I received a lot of abuse without any actual substance, and some abuse based on data but the data had nothing to do with the conclusion that caused the abuse. Essentially people who did not know the answer decided that...

I wasn't going to comment again here but given the stupidity of your comment I had to respond. If you actually read the 10 pages you would see the number of times I have stated that I have no issue with fuel saving. So either you didn't read the 10 pages and you are just making up a story, or...

I assume that this image is the lip seal, which appears to be corrupted in your example. I assume that there is no way to buy this from anyone, unless you can suggest a supplier? I found possible o-ring suppliers for the sizes that you mentioned, but I will have to contact them and see if they...

Phil, Thank you for responding, yes I would definitely appreciate your used O-ring. The only reason that I called it a solenoid is because when I searched for the part online that specific name came up a lot. I found one on eBay and they wanted £1,300 for it, but they called it an actuator...

I don't think you were directly insulting but I think you did made insulting comments about me to others that I could see. But there are a lot of people commenting here and I haven't really kept a track record of the level of rudeness of everybody. I was more just looking at the fact that 90%...

On that basis nobody should ever drive at 35 mph at the lower RPM? If the engine is cooled and has sufficient oil it doesn't matter. But higher RPM is more wear on the bearings, camshafts and cylinder bores.

Here is the torque curve for the engine. I am not concerned with fuel economy. I just want lower RPM on the highway.

If you look at the passive aggressive comments that started from the moment I posted here, I didn't get personal for a very long time. Comments like "you clearly know nothing at all about Mechanics" or something like that because I didn't agree with their stupid insulting comment. It's just...

Exactly, someone told me that I could not do this modification because no one modifies cars anymore. That was their amazing insightful input. When I mentioned that people do modify cars they got offended.

I am already slow off the mark, rarely using more than 1,500 RPM when accelerating so that is unimportant to me. If I am on a steep hill needing to go forwards or backwards slowly I can put it into low range for that special rare situation. But if I am doing a 6,000 mile round trip through...

Sills are fine, one arch is rusty and I'm fixing it this week. I just replaced all of the brake pipes and brake hoses on the car so I have been under it and in the wheel arches looking carefully at everything. There is also rust on the subframes and suspension that I was advised to do something...

Actually the only reason that you kept arguing and insulting me is because of your thin skins. If you had thick skins you would have shut up when you failed to prove a point. Like I said, I have watched this forum for about a year, getting actual information from the very few people that give...

Actually no, because every single person here who has given me a reason why the change would not work has given me reasons that are not valid. In fact the little data that they have presented shows that it would be reasonable. So that part of my question has also been answered and I just didn't...

if you guys didn't have such thin skins you wouldn't have thrown out so many insults that I have been laughing at. And because I have been laughing at them I don't have a thin skin. Maybe logic is not your strong point.

FYI iCarSoft said "From our experience, it is not possible to do suspension changes with any iCarsoft device on your vehicle." From what they have previously told me 2006 is the year where it changes, when the L322 used mostly Jaguar parts not BMW parts. So your iCarSoft should do everything...
