"Rear Airbag leak..."


  

          

LAST EDITED ON Nov-13-00 AT 04:44 PM (EST)

Well it looks like my rears are finally giving up. I have 115k on my car. It happened, partly my fault, after I adjusted the rear height sensor in the wrong direction and got a good 1 foot raise out of it... I turned off the car before it exploded, but looks like it enlarged one of the cracks in the aging bag. It has been leaking very slowly, but has increased to the point that it now sets off the Check air ride message once in a while. I tried to cheat and patch the tiny pinhole, but it just blew a tunnel in the patch adhesive and I now have a whistling hole. Here are the part prices i am currently looking at...

F3LY 5560 - Rear air spring

Ford Parts Network - $209
Arnott Industries - $100 + $25 Refundable Core
Bagmasters - No idea... 866-BAG-PARTS : $199 New (1st call $300)
One the phone they say they don't have reman's...
Internet new : $180
Internet Reman: $140
Local ford dealer - $271

So it looks like Arnott Industries... Anybody have any other price options?

I am happy to say that my bag is replaced and the highway rear end sway that I had is now gone. I had thought that something else was wrong but it turns out if you are riding too low with low rear end bag pressure the car will rock/sway back and forth at highway speeds. I got two birds with one stone on this one.

I went with Arnott Industries for the bag. Ordered online, next day deliver was the same price as 3 day, so I did next day. I ordered it on Tuesday afternoon and recieved it Thursday morning. I replaced it last night...

It was easy, but not as easy as the manual made it sound.

1. Turn off air ride system.

2. Raise car. (I just used the standard jack)

3. Remove tire.

4. Crawl under and pull wiring/fill tube off of the assembly.

5. Release the metal C clas retainer on the solenoid.

6. Turn the solenoid counter clockwise to the first stop point. The pressure will problably push it out to the second stop.

7. Wait for the air to bleed out. (I had to wiggle it to get it started).

8. Turn the soleniod counter clockwise to the third stop point and pull it out.

9. Release the bottom of the airspring by depressing the four clips on the bottom that connect it to the control arm.

10. Depress the metal locking tab at the top of the airspring and rotate the spring to disconnect it. The side nearest you goes to the right. I did not depress the tab and it only bent it slightly, no permenant damage.

11. Now the hard part... Manual says take it out carefully... I could not get it out of the space. I had to loosen the rod that the rear control arm attaches to. I loosend the top and bottom to their full extent without removing the nuts. I did not want to fight to get it back on. I then removed the plastic connector that holds the brake line to the swaybar and moved it upwards and out of the way as much as possible. This barely gave me enough space to get it out.

12. Insert the new airspring.

13. Manual says to put the top back in first then the bottom. I fought this for about 15 minutes and gave up. The angle that it put the bag at made it near impossible to get the bottom to the right spot. I put the bottom in first, put a board under the suspension and lowered the car to the point that the top made contact and made sure it was in both holes. I then gave it a good turn and rotated it into place with no problem.

14. Clean up the o-rings and put a touch of dielectric grease on them. Mine were still good so I did not replace them. Put the solenoid back into place. The second turn was a doosy and took some muscling to get it up and in, but not too hard.

15. Reconnect the electical connection.

16. Put the retainer back on the solenoid.

17. Put the tire back on.

18. Lower the car to the point that it is lower then it should be, but not completely down.

19. Turn on the air suspension and start up the car.

20. Pull the jack and put all your tools away..

It took a little longer than normal to get the rear up, but once it started up it was on its way. I am now happy to say I have a leak free car once again.

Sounds like fun. Good step by step, that's another one for the "when It Happens" book.

I know what you mean about putting the solenoid back in the last possition. I guess the fact it is the seat and is what keeps the air from leaking is why they are so tough to get back in. When I bought the front struts from arnott new solenoids came with them. They didn't come with the rear bags?

Nope, no solenoids with the rear. It comes with new o-rings but I did not need to use them.

Good info. I will post this on the suspension section of our club website. Reread your post and make sure there are not any errors. I will also post what the manual states as well. It is always better to hear first hand what it is really like to do the job.

As far as bag options, I was talking to someone yesterday about bag options for our cars and he seemed to think that there was a custom application that could be used for our car. This bag would be able to accept bigger lines for increased rise time for those that want to do a custom reserve tank system.

The suspension section is not up yet, but I will work on it tonight. There is a link under the modifications section to a lot of suspension info, but that is not where I plan on putting it. All of that info will be moved to another section soon.

I looked into finding some custom jobbies but could not find any...

It all looks good in my post, minus a few typos and clarifications... In 5 it should say clasp not clas. In 11 I put in a lot of it's... move it and it and it... If you can put in move the brake line out of the way and pull out the bag, etc. that might make things clearer.
