Rear Riding too Low. Sagging


TONYUBALDO

Recommended Posts

Good MOrning Guys,

I have a 2002 seville SLS

well i've notice that my rear is riding too low it looks like it saggs from the rear. When i turn on the car i can hear something in the rear turn on i guess it might be the compressor. I ran it for codes and i have none. I inspected the shocks and they have some rubber boots or something but they feel soft im guessing maybe thats were they supposed to hold the air. I'm not really sure on what i should be looking for, can some one maybe explain to me on what i can do to identify the problem?

Thanks alot

Does that motor stop running? If not pull the fuse for the ride air compressor before you burn it out

It sounds to me like you have a leak in the 'air shock' tubing or the air shock bladder

ok ill go head and do that, how can i check if i have a leak on the air shock or the shock bladder?? do you happend to have a diagram of where everything is on the car? i would appreciate it

Take dish soap and mix it with water, the more dish soap the better, using a brush or spray bottle, spray the bladders and any lines you can see, and turn on the key, if your compressor is still working it will pump us the system with air, look for bubbles, if you see bubbles you have a leak.

Also listen carefully for leaks with the key on. It would be best to have the rear of the car up to get at everything, but jacking one side at a time is also ok, take the wheels off

thank you body fisher i will definetly do that today if its not raining when i get home from work.

Can you tell me where the compressore is located? please thanks

The level compressor is located in-board of the the passenger side rear wheel above the frame,

I would focus on the bladders first, you might have kicked something up that tore one or it became porous

Yes, they are rubber, and they are under pressure when blown up by the compressor

Can the bladder be replaced on its own? Or do you have to replace the whole strut?It is extremely expensive to replace the struts...my car is a '94 and they are over 900$ each, which is why I haven't bothered yet. I would imagine them to be even more expensive on a 2002.

I hope for your sake it's an air line. MUCH cheaper to repair!

Nope you have to replace the strut.

Not to worry you can always purchase after market struts from Arnot Industries, all 4 are $581

Thank you Mike! I had browsed around a bit looking for after market ones, but I wasn't having much luck. Most of what I found was close or equal in price to the OE ones.
