I'd better double check the levels!

HI

Seems a little odd, raising and lowering the body has no affect on the position or angle of the diffs

Steve,

yes it does. Think about the arc created by the radius and trailing arms as the air springs inflate. The diff gets more vertical the lower the car is. As the car rises, the diff swings "under the car", closer to the horizontal - albeit in single digit degrees.

But I believe we're talking about mm's of difference in terms of the fluid level in the diff housing. Not enough to be concerned over.

It's noticeable if you're looking for it ;-)

Just want to confirm this again, I changed out the diff oils on the weekend and didn't notice until I'd finished how much they turned. I lowered it and filled them both again and they did take a few pumps more.

Well I finally got the bumpstop extensions and spring extensions on. We went for a drive today and I have to say it is very effective.
Quite impressed, especially with the front atb diff.

Hi everyone.
First of all, very good post, I have read it a few times, and thanks for the support and advice also from various members.
Apologies for throwing this on the end of this post, but it seemed like the most practical place to put it, other than starting another suspension thread.
You've probably seen my recent posts and I have been thinking of starting a suspension lift on mine. My lift may be for different purposes than what you guys may have done. My reason for lifting is to be able to get a better flex at a higher suspension setting. As you will all probably know, that there is not much flex as the suspension starts raising, so that is my first objective.
Now as this is what I want, I am trying to use as much of the available space as possible, I'm don't really want to go to the trouble of lifting, if I then need to limit the upward travel by fitting longer bump stops.
I have just tried to put the car on the bump stop, and see how much I can lift the bag up by. ( therefore giving me the maximum free space ) I didn't seem to be able to achieve much. can any one confirm, that the spring will collapse a little more than what is does while on the bump stops. I thought the purpose of using bigger bumpstops to stop the height sensor going past its lowest setting? I may now think it is to stop damaging the spring if it was to compress to far. My plan was to keep the access height as is, and adjust the position of the sensor to allow it to raise higher while still giving the same reading. it works in my head, honest.

I recall being concerned about smashing up the top hat of the spring with the piston, after fitting the lift spacers. I dropped the car as low as it would go and jumped on it to see if there was contact. There wasn't, but I'd already added about 15mm to my bump stops. I added another 10mm or so, as a safety margin. A bit of trial and error really.
