Buy a vacuum pump and put the crank case in a vacuum, then it won't leak.

My Eibachs actually did settle from initial install, not a lot just from driving around a bit. From when you install them, load isnt 100% yet...

X3 on a DSM, and a lot on other cars.

Sounds like whoever built/assembled the engine should be responsible for that leak, not you. Any reputable place offers at least a defect warranty. This was ERL or something, right?

I guess I'm just a lot more particular with the assembly than most; I've installed lowering springs on numerous cars and never had one "settle" after initial suspension compression. Oh well, either way, doesn't matter.

Few questions...

Does the rear diff and tcase use the same fluid? (It looks like it does minus the AYC part) Also should the AYC fluid be changed as well?

And what do people put in those? Stock diaqueen? Or is it worth it to upgrade/change? I need to change that fluid soon, including oil so I need to go buy some.

[Kracka]

OEM Mitsu Diaqueen 90W LSD in the transfer case and one part of the rear differential. OEM Mitsu Diamond ATF SP3 in the other part of the rear differential. These are all simple drain/fill fluids; the AYC/ACD hydraulic fluid (also Diamond ATF SP3) does not need to be regularly changed or bled.

Thanks Kracka, you da man! Others have said they switch to Motul fluids but I like the Mitsu fluid path honestly. Now I know what to use.

So the AYC/ACD should still be fine at 30k miles I am guessing? or should I swap that out?

[simulatedwood]

+1 on the mitsu fluids. The one gallon of the of Diaqueen will last you a couple diff changes. Both sides should be changed in the rear differential, but you do not need to change out the ACD or AYC reservoir or bleed the system. Does that make sense?

[Murlo26]

Yes, I just wanted to make sure I didn't need to bleed and/or do the reservoir. Going to order up the two Mitsu fluids and put it on my to do list.

Ask me again in 10 years/100k miles :) That fluid is not considered to be scheduled maintenance.
