I have an 87 TDT wagon with hyd suspension. Awhile back I blew a hydraulic line to the rear and lost all the fluid. I think it was a few days before I noticed it as my wife drives it mostly. I repaired the lines refilled the tank with the proper fluid and the way I went. Well it seems to ride rougher than I remember. How do I go about making sure it is working properly? I have unhooked the leveler and moved the lever and the car will go up and down. I have fluid comming back the return line. Is it posible that there is air in the system? I bled it at the valve and all seemed fine. Is it possible that the leveler is set too low? How can I make sure there is pressure to the rear "shocks"? Thanks in advance.

The SLS is a self bleeding system, so any excess air will be bled. The bleed nipple if more for transfusions.
If your car is sitting up in the rear, and raises and lowers with the linkage, than your struts are getting fluid/pressure. The shock absorbing happens in the accumulators (or spheres).
Which line blew out?

Up on top of the axle is where they were rusted. The one that went to the bottom of the valve rusted through so I changed them both. Is it possible that the car is set too low? When I hit a good bump I think it is bottoming out on the passenger side. How do I set ride height? Or is there someplace else I should check?

Ride height is set by the length of the lever. On mine [W123] the shorter the linkage, the higher the car will rise.
This is probably a dumb question, but in replacing those two lines, is it possible that you got their locations reversed? (only ask cause that is something like I could to)

**FYI**
I am assuming your W124 SLS is basically like that of a W123

bouncy ride= accumulators (Spheres) are worn out. on a 123, anyways.

FWIW, the fsm says to bleed system, jump up and down on rear bumper.
or was that the haynes?

It could be possible that you moved/bent the adjusting rod when changing lines?

if you get the ride too high, it is really rough riding. send the kids thru the roof, if ya know what I mean.

Well it was working good after the line change and I replaced one at a time to insure that I got it right. Where are these spheres located? Mine is the W124 chasis.

Follow hydraulic line from struts, and one leads to a sphere. Usually above each half shaft, in front of fuel tank (if same as W123 of course)
I've replaced accumulators on both my wagons. Like replacing shocks on a sedan, as for effect.....
