How do I replace the grommet for the antenna?

If you need to replace the cable as well your getting into one large project.

In order to replace the cable and mast on an Astro Van you will have to take the completely lose to roll it forward, or take it out. There is a clip and grommet that have to be accessed from between the hvac and the dash.

It's a large project.

the cables go in not out.

Use a 13mm (possible 14mm) open ended wrench on the chrome ball attached to the body with a black seal around it. The wrench will only fit on one way. After you unscrew it slide it up over the antenna. You may have to loosen the antenna motor on the right hand side behind the trim (a couple of 8mm bolts if I recall) and then you can cleanly remove the grommet and replace with a new one. Reverese the removal procedure to reinstall.

Good Luck.

a rubber duck type aerial is best(the b......s can"t rip it off)and the good news is you can but them with the offset grommet as standard at most accs shops.start at the aerial end and tape one end to the other so that you can pull it through.

open front door you should be able to grab antenna cable with a wire clothes hanger.fish wire through grommet behind the kick panel.pull radio out fish antenna wireunder dash to radio opening and then plug into back of radio antenna jack then reinstall radio

1. Disconnect negative side of battery.
2. Wait at least 2-minutes to de-energize the airbag system
3. Remove the glove box from the dash.
4. There will be a coax cable towards the top of the opening. Disconnect the antenna cable lead.
5. Remove the right kick trim panel. There should be no screws just clips.
6. Loosen the rubber grommet insulator from the door hinge area. This is a rubber accordian style guard for wires located between the "A" pillar and the door.
7. Pull the antenna cable out of the dash area to the hinge area.
8. Jack up the front right of the vehicle. Support with Jack Stands. Do not use only the Jack! Use the jack as a back-up in case of Jack Stand failure.
9. Remove the right front tire.
10. Remove the right front wheel housing splash shield. There should be 3-push type retainers and one 10 mm bolt below the bumper.
11. Slide the plastic cover (on the base) up on the antenna mast.
12. Use a open end wrench to unscrew the antenna mast at the base and remove the antenna mast.
13. Remove the plastic cap from the base nut on the base and remove the base nut.
14. From underneath the fender: pull down the antenna base. And pull the cable towards you - out from the door hinge area into the fender area.
Good Luck! Installation is reverse of above.

you have to pull out the trunk interior trim panels on the left side to access it.
there will a few 10mm bolts and a connector.

On the 92 you have a rubber grommet in body,then you see black plastic insultarer and chrome fastener! Most junk yards have them for a buck or two. 91 should fit also!

Start by looking under hood at firewall, there is usually rubber grommets for other items that you can use to poke in along side of them. I usually go in by speedo cable, steering shaft are, just make a small **** if you have to. Look around for one that is closest to your antennae mounting location. Cellular antennae, I guess stick on the glass type not available, or preferred?
