@RRMaximus you have alot of perseverance. You keep on bleating that you want to lower your RPM but if not fuel economy then why? If its for engine longevity you do realise that a lower RPM but higher throttle request cause higher cylinder...

If the airbags show signs of cracking, they will be leaking. The leaks open and close where the bags fold so leaks are not always easy to detect. The bags have an 8 year 80K miles design life. They are not very expensive, I replaced all four...

Jack it under the axle & put axle stands under. Then height sensors are easy even on the bumps. As others said get some schrader valves as well. Then you can raise it up, while fixing the pump.

Yes I am relatively new to working on cars ,so owning old landys is definitely going to teach me the hard way . Trying to not just throw money at it until it works.

I hate to like it but, we have all been there and feel your pain :oops:. And yes I have been through it on a P38 and an L322, glutton for punishment some say, we will learn from this,is another way. So what explains us doing it...

A replacement air compressor is on the way, as I took the old one apart and now it doesn't work at all😅😅. Due to the car being on its bump stops getting at the height sensor is a little difficult I've been expecting an air suspension fault...

Oh and the famous white connector behind the kick panel. J

The thing is if you dont have operating pressure in the system it may not leak. You need to spray the bags around the folds. The "going to off road" some have reported that before, but I dont know if it was ever resolved. But it could be sensor...

Cracks in the airbags will almost certainly be leaking

The air bags are Dunlop and are very dry cracked so I assume there original or atleast very old. The air suspension has been fine up until yesterday it even , stayed in standard ride height over night. I sprayed soapy water on the air tank...

At that age you probably have 4 bags past their shelve life and it only takes 1 to leak to get the car to lower over night. So was it up when you left it and down the next morning? You have probably been feeding a leak for some time and the...

Checked the line on the air tank, all seems fine dirty but fine. A worn piston seal might be the cause , as when I turn the car off you can hear the valve block releasing air , even tho the car hasn't raised.

It may be running but is it making any air. If the piston seal is worn you will get very little pressure.

I'd be checking around the air tank to make sure the air supply to it hasn't been popped off? A good clean up needed then and a thorough examination of air lines and airbags. 👌

On a different forum someone explained the outcome, because they knew someone who did something like this, and they said it was fine, just less acceleration.

And yet I am not increasing the fuel economy with differentials, which I have explained so many times now I have lost count. It is like you didn't read anything that I said. Which once again proves my point about this place...

Just be careful the thread isn't stripped out of the aluminum bracket. A dab of thread locker or Loctite on the bolt and it should be OK 👍

Think of how much easier it will be for the next person searching how to increase fuel economy with differentials. They’ll be giddy. It’l be like he did all the work for them

This thread has been quite the read. 270 posts in a matter of days and presumably it'll keep going. I'll be honest, I'd be fascinated to see the outcome...

I did everything to the proper tightness apart from the 2 ball joints on the hub but thought they were "tight enough" 🤔 I did reuse a bolt for the arm>chassis on one of the arms because i forgot to buy a new one 🤔🫣🙄

Check the tightness, a lot of the big Landy stuff needs to be vain popping tight. Especially on the multi link stuff 👍

Well i made progress on my suspension rattle. When i replaced the arb drop link, the "special washer" was missing, so i didn't use one. It was fine for a while but i think it started to rattle - just fitted a washer and the rattle has gone...

Maybe loosen it and faf with it a little. The proof will be when you warm the engine and check your work👍 Are you sure the o-rings are correct for the application? 🤔

As long as the collars on each pipe sit against the black plastic they are are home. The aluminum collar should be sat equally across the pipes in relation to the black plastic receiver 👍

"Bend over and take it" means to not respond and just accept being insulted. I did not do that. I was insulted and patronized and for a little while I tolerated it but after about the 10th time I had enough. I eventually decided not to bend...

Hull is cold in a different way, when you walk into a pub EVERYONE turns to look at you..... you wonder why but its the fact you don't have webbed fingers.

Admittedly I have never been to Hull, so not necessarily colder, no :)
