What could be the problem with with damping on the back axel

Peter,
Now I see your question where you identified the model vehicle - when you post info in separate questions it is harder to help - Fixya allows you to add info to the original question via comment. What year? Here is a video that may be helpful:

The rear height sensor may have disconnected from the axel. The height sensor is mounted to the
body above the axel and it has an actuator arm thats connected to the center of the rear axel.
When the body comes down the arm go's up, this engages the compresor and inflates the suspension to a preset height. Start with the compressor, turn the key on and you should hear the
comp. run for about 10-20 seconds then turn off. If it won't turn off check for air leaks. But if it works
normally, check the power+ground connections and the actuator at the height sensor.
Hope this helps.

You will have to remove the rear end plate off of the back of the rear end. Then turn the carrier untill you see a big silver pin that goes through the spider gears. Those will be 4 small gears in the rear end carrier. If you look at the right side of the carrier were the pin goes through it you will see a small bolt head, That bolt goes through the carrier and holds the pin in place. Remove that bolt then reach up in the rear end housing and push the pin towards you untill it comes out. ( DO NOT TURN ANYTHING AFTER YOU REMOVE THE PIN) are the spider gears will fall out.


Now get someone to push the axel in while you are looking at the 4 small gears in the housing, when they push the axel in a C-clip will fall off the end of the axel and into the rear end, You will see it fall out. Then just pull the axel out.



When you put the axel back in, push it all the way in then slide the c-clip over the end of the axel and then pull out on axel and that will hold the clip in place untill you put the big long pin back in the carrier. I hope you understand, just watch what you are doing. GOOD LUCK.

Sounds like you have a bad air shock.

you are going to have to jiggle and pry they also make a axel tool to hammer in but the ring on tip gets caught and it is a pain.try twisting and pry from more than one direction if you can like lift from bottom pry from top or side. good luck you will get them.

if you have not yet replaced the clutch master cylinder , that will be the cause of the problem
once that is replaced the pedal will come back to correct height

It has to be replaced. If its front new break hose that runs from hard line to caliper. If rear from caliper to block on rear axel. If main line from front of car at perporationing valve back to block on rear axel.

clicking noise could be the speedo cable. vibration could be tire related

hi art , i think they are going to call it ride height in the alignment specs . front ride height would be 9.0" - 9.8" and that point of measurement would be taken at the rocker panel 23.5" back from the center of the front axel (center of tire) to the bottom of the rocker panel .and the rear height would be 9.05" - 9.85" , and that point of measurement would be 23.5" from the center of the rear axel forward to the bottom of the rocker panel .see pic

i assume thru the rear cover? Remove cover and check for spider gear shaft pin being broke.While in there of course inspect all gears but pin most prone
