6.9 Suspension Issues Please Help

My car needed new accumulators on the front end. I started with the right hand side one. While installing the entire car went flat. After I got the new accumulator installed I started the car and the ass end came up and the front wont. I opened the bleeder valve and I'm getting air and a hit and miss squirt of oil. The tank is half full so I know its not the fluid. The rear end came up so I'm thinking the pump is strong still. Is there something I'm missing? The job was pretty straight forward.
1. Is there any way to reverse bleed the system with the car off?
2. Where is the front ride height valve?
3. Does anybody rebuild these valves should I have a problem.

Thank you

You could check the M-100 forum, The International M-100 Group. Lots of answers in the forums. There may also be an M100 forum here.

There is a W116 forum though.

Not part of the in-crowd since 1952. It's BRAKES not breaks. You break a bone, use brakes to stop your car. /rant

1) You should not need to, how long did you run the engine?
2) Right under the climate control servo on the right side firewall
3) I believe that star motors does in NY but I have never used them.

The height control valve in the front is the same as the one in the rear. There is a rod that attaches it to the valve to the body of the car (same as the back). These have a habit of breaking and when they do, the height valve will not adjust so check this first.

Good luck.

With best regards

Thank you

Guys thank you for the replies. When I was a kid I grew up in a small farm community in Nor Cal. It was rare to see a 6.9, but at the age of around 12 years old I knew that was the good one. Im 38 now and starting to relive some of those childhood memories. The car I bought has great paint and a solid interior. The car runs well but has quite a bit of rust. The spheres on the front are shot, but the ones on the rear are fine. Its frustrating trying to move forward with this car to be set back. I know if I take the car in they will shot gun parts into the car and send me a bill for 3 grand. I'm going to order the other 2 spheres and install them next weekend. If the front of the car doesn't come up I'm going check to see if there is pressure on both sides of the ride height control valve. The ass end of the car is working perfect. Wish me luck and thank you for taking the time to respond I really appreciate the effort.

-Brian

Check the rod that attaches to the body, I've had to replace this 3 times on various 6.9's that I owned. It looks like a mini tie rod and like a tie rod, the rubber bits go bad and then it will disconnect from the valve.

Without the rod, the valve won't adjust so if the car is sitting down, it will continue to sit down.

With best regards
