Can the radio volume nob be replaced?

1. Try not to be a jackass right off the bat.
2. I was merely suggesting he verify the knobs themselves not be stripped, which could play a role in the issue being described. I seen plastic wear out before metal with much more regularity.

 

1.) Try not to be so sensitive.

2.) I call them like I see them. I only posted the facts.

OP, Good luck in cleaning the pot.
I haven't been in one of these particular stereos and a warning that the pot may be a sealed unit...

 

Get that you are saying the knob itself could be slipping on the shaft itself,the should check that first,and then do what Jimmy says,so you both could be right.

 

I said in my first post it's the POT/contact points and not his knob. The aftermarket knob does have a set screw based on the description. That MAY make the contact between the knob and the shaft better and make the volume adjust more accurately if the pot is good and cleaned.

I still say forget about the stock head unit but he seems to like the look.

Me if I wanted to save the thing I'd probably tear it apart use a meter and check the pot confirm its bad and then replace it but it's not worth it in my opinion to do all that.

 

I have a fix. My unit is fixed and working great!

I've seen so many people just say they replaced the OEM unit with a new stereo when the stock stereo works fine other than the volume control. This is a $5.00 part and if you're a little electronics savvy it can easily be replaced. You'll just need a good soldering iron and a solder sucker or solder wick and some basic tools.

I was not able to locate the exact ALPS control in the unit. I'm guessing ALPS made it special for Delphi (who made the stereos for Toyota)...not sure. But either one of the ones below will work.

Here are the two ALPS models I ordered from Mouser Electronics

EC11E15244B2 11mm 15 RES 30 DTENT
EC11E153440D 5 Volts Through Hole / This is the one I used but either one would work

There are plenty of YouTube videos of how to remove the unit from the dash so I didn’t go into that…it's very simple (4 bolts).

These ALPS encoders can be ordered from many different suppliers such as Mouser Electronics, Newark, Allied Electronics, etc…just Google the part numbers.

I also took the old encoder apart and confirmed it was 15PPR (pulses per rotation) so I did order the correct types mentioned above.

The two different types I ordered are physically the same size. The difference is one of them has 30 detent's when you turn it and it has the original 1.5MM travel for the push button (power). I used the other one I bought with no detents (smooth when you turn it like the original) and it has a shorter .5mm travel for push button (power) which worked fine.

The only minor issue is the shaft length on these is slightly longer than the original (~1.5mm or so) you could still install it as is and the volume knob would just be slightly taller and no big deal but I ground mine down to the same length as original using a bench grinder. The shaft is aluminum and is easy to grind down. Just make sure you hold the shaft with pliers as not to stress the encoder and cause damage. The other issue (which is really not an issue) is these do not have the groove in the shaft that helps hold the knob. I found the knobs are plenty tight without the groove and absolutely do not pull off unless done intentionally.

I hope this helps some of you. Questions, comments, ideas are welcome.

 

Damn fine job!

 

Thanks Jimmyh

 

After reading This entire thread . Now I know I'm going to just buy a new aftermarket head unit LOL probably Alpine

 

Thank you! Was sitting in the parking lot thinking of this issue. Read the post. Pulled off the knob gave it a good blow in there and now works much better.

 

I really hate to revive this thread. But i have a feeling replacing the knob controls doesn't "fix" the real problem...and here's why

I had a 06 tacoma that did the same thing for years, you turn the volume button down and it'll go up and down on its own. I was going to replace it with a aftermarket radio, but ended up getting a newer truck, a 2012...
To my surprise, the 2012 did the SAME THING! so at this point i thought new radio right away! I put a double din android radio...guess what... does the SAME THING. Funny thing is, i can use the volume controls on the steering wheel no problem, but the minute I use the knob, even on the aftermarket radio, it does what it wants...
