My wife called and said it sounded like a gun shot (I have no idea how she knows what a gun shot sounds like). I had her start the EX and the compressor was very loud. I opened the hood and I found the side of the plastic canister attached to the compressor had blown out. Their were all these plastic beads around it. I drove it (very slowly) on the bump stops to the dealership. I really don’t want to know how much this is going to kill me $ ...

 

New compressor so far, they have to do a final check today. Anyone have any idea why they put those beads in the unit? I am thinking because they look like the beads that come in those anti-moisture packets, they are pretty tasty btw
Isn't moisture a concern with regular air compressors?
Looking at an '03 EB today. Any options I should stay away from (beside the LLS)?

 

What year model is this EXPY? I have 1998 with 4 corner LLS with 115K miles and no problems with it. I love this system for towing.

 

Me too! I can't imagine towing without the LLS. It's great and no problems here!!

Now that I'm looking at Excursion, it's probably going to fall apart. I parked right next to the one I drove today so the Expy saw me drive off in a new Excursion. Nothing yet, but I wonder if it's planning some way of getting even with me.

 

it's a 98 EB. I am begining to wonder if it might be the weight of the grill gaurd causing it to have problems?

 

yeah, its got to be the grille guard !! My compressor used to be fairly quiet, it has since started making some funny noises, actually, its just much louder than it used to, but sometimes, and this is rare, it will operate almost silently, but most of the time, sounds like a machine gun.

 

Yeah the compressor on my 98 is noise as hell. But it still work great.

 

Where exactly is the air compressor located?

 

looking from the front of the car towards the back, with the hood open, its directly behind the passenger side headlight.

 

I have the new compressor is in and it seams like it is running a lot more. We took the Expy on vacation and the check susp. light came on 3 times. It did not come on during the trip home . Any additional thoughts?

 

1 week old and the new compressor blows up!!!!
Again, while making a left turn.
Ever get the feeling your dealership does not know how to investigate a problem?

 

BuckEye,

I have been having some similar probs with my 00' lls, what was your end result??

Thx

 

Knock on wood, 61k miles and no problems and that's even towing some good weight.

 

The compressor on my 01 Expy wore out its mounting bushings and started to make a loud noise and vibration. I have since replaced them with plastic washers that have silenced the noise to a low rumble and reduced the vibration. Nice eh?
For those of you do-it-yourselfers, access to the compressor requires removing the battery and battery box, removing the window washer reservoir on pushing it aside. You can then get access to the compressoer and change parts out. I wouldn't pay anyone to do the work since it's real simple.

 

The beads are dessicant - used to dry the air in the sytem.

When I first got my truck the Check Susp light would come on after 1/2 hr on the highway. After 5 or 6 tries, the dealer found that the right front shock air line was cross threaded.

The compressor used to run constantly (due to the leak). After the fix, it only runs occasionally but I wonder how much wear was put on the pump by all that running.....
