:: GruvenParts.com REINFORCED Spur Gears for GM Folding Mirrors ! ::
2007-2014 GM Trucks Folding Mirror Reinforced Spur Gear - Click Picture for the Product Page !
Gruven Parts | Custom VW Parts | Volkswagen BMW & Audi Auto Parts is pleased to announce our replacement Reinforced spur gear for the folding mirrors on 2007-2014 GM truck including Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali.
This product carries a LIFETIME WARRANTY!
Gear Installation DIY Is Now Available ! Visit Our Product Page to View
As many have discovered, the folding mirror assembly on these trucks suffers from 1 weak point : a spur located within the mechanism is very weak and strips or cracks over time causing an inoperable folding mirror. Unfortunately, GM will only sell you the complete folding mirror assembly, which ranges from $700-$1,200 ea depending on the year/make/model (after labor and paint).
And that $ would be spent just to get another faulty mirror assembly with a weak spur gear that will soon fail.
GruvenParts.com has addressed this issue by designing a reinforced spur gear to eliminate the cracking and stripping which is occurring in the GM spur gear.
Sold as a set of 2 – enough for 1 vehicle! Gear Fits Both Passenger and Drivers Side Power Folding Mirrors.
Application :
All 2007-2014 GM Trucks With Folding Mirrors Including Escalade, Silverado, Avalanche, Tahoe, Suburban, Sierra, Yukon, and Denali. This includes (but not limited to) the following mirror assembly part numbers :
25-83-12-36 (25831236), 25-77-98-49 (25779849)
This list of part numbers will continually grow as we build the interchange list. This is in no way complete, as most GM trucks made from 2007-2014 with power folding mirrors will use this gear. If your power folding mirror looks like the mirror shown in the DIY, this gear will fit your vehicle.

Hey if you go replacing those plastic gears with the all those metal ones, you are going to ultimately impact your over all MPG after about 3,000,000 miles... just sayin'

Let me be honest and say that until you get some clear instructions on how exactly to break the mirror down to get to the gear, you may have trouble getting pre-orders.
And no, don't bother with the links to some youtube video that somebody else made 5 years ago. We need "real" instructions. From you. I've watched all the videos and read all the threads that I can find. I can't even get the chrome cap off without destroying it. And I'm a guy that tears anything down and puts it back together again, typically without instruction.
People aren't going to order if 1. they have to spend more money because of all the other stuff they break during the teardown process (basically just easier to spend the money all at once for a new one) and 2. they can't confirm that the gear is even broken. Why order the part if its not the gear and the motor is out?
Just my 2 cents. I appreciate the effort in producing the metal gear, and I want to order, but I'm not going to pre-order until I can confirm. Pretty much that simple.

OK I get that.
I dont have a video at this point of the tear down but the step in which you must separate the metal case halves involves slightly spreading the case apart to disengage the locking tabs. At that point the 2 halves come apart, revealing the guts of the mechanism. This particular step isnt too difficult, i just used a vice to hold 1 half while spreading the case using a flat head screwdriver and prying the upper half off.
Unfortunately GM didnt make this very easy, but the option of plunking down $1000 on another faulty mirror assembly is absurd. If your mirror is flopping back and forth and wont fold in, you can be reasonably sure the gear is to blame. Its really the only plastic part in the assembly, and its very very brittle.
Can you post a DIY on getting to the metal gear assembly case ? I will put together a DIY on how to separate the case and remove and replace the gear. Please let me know if you can do that to get this moving !

Ok I think your missing the gist of my post. I understand where you are coming from on the separating of the metal case...even without seeing it, it seems fairly straight forward.
As I see it, there are about 4 working details to this whole thing:
1. Removing mirror. (Probably the easiest part)
2. Taking off glass, "colored" cap, motor (or whatever is necessary) other plastic housing pieces. (Hardest part as I see it)
3. Taking apart metal case and replacing gear inside. (2nd hardest part)
4. Reassembly. (Second easiest as if you made it this far, you can probably handle it)
That said, #1 I think anyone can do. #3 I think could be figured out fairly easily (as you have even stated). #4 is self explanatory if you made it to step 4.
The hard part is step 2. Most of us don't have "flopping" mirrors. We have mirrors that simply won't power fold but will manual fold. OEM replacements are in $4-500 dollar range, and take offs can be had for about half of that. I think we (when I say we I mean those with broken power fold mirrors) are all willing to pay $50 for a part to save say $200.
What we aren't willing to do is break the housing the mirror is in now, break the colored cap, break the mirror glass...etc etc. that could happen during step 2.
I'll explain my situation further. I saw the idea about the gear well before you decided to produce a metal one. I had every intention of taking mine apart down to that level, get the gear out and see if I couldn't piece it back together with some special welding glue we have at work for this type of thing. I watched all the videos I could find. I read all the threads I could.
One day I pulled the mirror off. I can get the glass off (with instruction from alldata) without breaking it. What I couldn't figure out is how to get the chrome cap off without breaking it, the tabs that hold it in, or gouging it up on the outside in the process. After breaking one tab I gave up and put the mirror back on.
Why did I give up? Because the mirror still looks good and still works fine with that one exception. And my fix was about to be more costly than anything else, and who knows if I have a dead motor or a broken gear? So for the odd time I want to fold it, I'll just manually do it.
Thats the long and short of it. We need proper instruction for #2. No one out there has it really. You have a test mirror with a broken gear you don't mind me possibly breaking the housing you want to send to me to make a video of it? Lets do it. Send an extra one too, so after I do it and break it to figure out how to do it right, I can do one right for the video lol.
All the videos I've seen to date seem to skip over some of the important areas of disassemble, or they just didn't care if they broke something because they already had a replacement on hand, or they simply don't care of the housing looks like someone attacked it with knives and screwdrivers lol, just as long as it works and their youtube video gets hits.
If you have a lock on a video that clearly shows step by step how to do this without breaking stuff, I'm all eyes. I know that you still stand the chance of breaking stuff, but thats the case in every diy repair I've seen or done.

I dont have an assembly to send you so we're going to have to work through this as a DIY.
We can make the gear in metal, already have the CAD files for it and a vendor standing by to build them for us. But will need some owners to step forward with this vehicle and help out by helping post the replacement instructions. I do not have them, my expertise in this is getting you the metal gear.
I can assure you that if your folding mirrors are not folding in but you can hear the motor whirring, its is most definitely this gear in question, and no you cannot glue it back together as the teeth on it are very small. The plastic gear literally crumbles in your hands.
Im confident we can come up with repair instructions between all the resources on this forum and our contacts with GM dealers, but what I need to know at this point is if anyone really even wants this metal gear fix. So far we only have 2 gears on pre-order so we are not going to put more time into this until others express interest.
Given the fact that removing/replacing the gear without breaking the housing WILL be feasible (and in fact is done everyday at most GM dealerships), do we have any other interest in the metal version of this folding gear ?
Anyone who wishes to help out by working on the DIY articles required to remove and replace this gear will receive a free metal GruvenParts gear to evaluate. Before I make those metal gears though, I need at least some interest in this.
Please post back here or email us.
