How-To: Replace OEM Antenna (in-fender)

WOW! This is good info thanks!

 

I did this replacement several years ago, think i even referenced this thread…so thanks for that!

However, the real problem here is a poor design from toyota that quickly results in galvanic corrosion causing poor reception, stains, etc.

I ended up switching to fiberglass fenders about 2.5yrs after i replaced the antenna. When doing so i found the corrosion on the antenna to be the same or worse than it was originally. I didnt even bother to re-install the antenna (usually listening to satellite or Spotify anyways). But i do miss having the local stations sometimes…

Moral of the story, someone should step up and design a better antenna!

 

I wonder how well reception would be if the antenna was tucked out of the way in the headliner?

 

Glad i found this, was thinking my radio was the issue. Still planning to change the stocker out sometime soon.

Does anyone know the part # for the actual antenna mast? Didn't see it posted in this thread anywhere.

Have to do the same, my boy's antenna broke off in the car wash today.

ETA - found it. 86309-04110

Ordered the exact drill bit and extractor as above a week or so ago. Have sprayed penetrating fluid in the antenna base a few times since then while waiting for the parts to arrive. Me and my son removed the broken antenna stud from his truck today. 2015 with 135,xxx miles. Followed the process above and it worked like a charm. Slow and easy, took our time, and it came out with no fuss.

 

Do you happen to have the links to order the bit and the extractor?

 

Ordered them off Amazon

BOSCH CO2132 1-Piece 5/64 In. x 2 In. Cobalt Metal Drill Bit
Irwin Tools 53401 SCREW EXT #1 SPIRAL

 

The fastener holding mine on is frozen. What are people using to break it loose?

 

So, I've been putting off replacing my antenna for a few years since is was damaged by a falling branch, and I found a stubby antenna that I liked, and thought this would be a fun, easy, and quick project.
I found this thread and a video before I started on it, and I'm glad I did - had to cut off the original "antenna ornament" as it had fused with the base of antenna assembly... Picking up the replacement parts (antenna assembly, antenna nut, and "ornament") tomorrow, oh how I love removing the stupid plastic clips and rivets...

 

Replaced mine as well, thanks to the info in this thread. I had the corrosion stain on the fender and poor FM reception.
I had to drill my base out. Be sure to tape around the area to save your paint in case of an oopsie. I first used a 3/8" bit, then 7/16". The corroded grommet finally broke loose of the base. I didn't need to remove the fender flare to get enough access. Just the mud flap and a portion of the fender liner. This is a good opportunity to clear out any dirt/leaves debris behind the fender liner. It's not too difficult, just take your time.

Replacing the antenna base improved the FM reception. Success!




All Done!

 

OP.....I know this is a bit of an old thread but that was a pretty solid write up.

 

Just thought I'd add a remedy here that I undertook, and am VERY glad I did. I installed a "shark fin" type antenna on the roof of my '07 Taco. It was NOT an easy job because of the headliner and all the attachments, (handles, hooks, sun visors, etc.).

I opted for a 12 volt assisted one and the reception is incredible. Only cost a few bucks on Amazon.

My only issue has been trying to find a nice looking piece (preferably contoured specifically) to cover the hole on the fender. I ended up using some scrap black plastic and dremeling it to look half way okay.
