Hey Unruely I would also like to publish that on my site if that is okay with you. It is a great 'How To' and found it covered everything, which is excellent for newbies etc.

Your local hardware store or Home Depot will carry it.

I found that it's easier to buy an aluminum spool. I've had the JB weld crack and break.

Well did that happen on your first run?And also I understand that you had to upgrade to aluminum gears,but I am not ready to do that now.I really don't want my truck to be heavy,if you know what I mean.
Thanks for the tip dleigh007

No idea on JB Weld as I don't use it. You can always upgrade to our aluminum locker and keep the remainder of your stock gears. Never had one of our lockers fail...

Note! I did this a while back on my Clodzilla 4, it is geared more for
a novice than someone with experience. I did this to show someone
who has never done it a detailed set of instructions on one way to
accomplish it.Your comments and suggestions are more than
welcome.

Part 1:

I'm going to try and provide a guide on how to lock a differential
on a Clod truck. I decide to do this project after searching and not
being able to find a good description of how to do this anywhere on
the web. I am by no means an expert on this, but my method works.
There may also be other ways of doing this. The advantages of a
locked diff are greatly increased traction while pulling or climbing.
The disadvantages are increased turning radius, somewhat
increased wear on tires and some driveline parts. I have found 2
different glues that work well for locking the gears; both are 2 part
epoxies, which require mixing. J B Weld, and a new product I found
at a local automotive supply store called "Plastic Welding System"
it is designed special for plastics. (See pic 1-2)
Image
Next. It’s time to tear things apart. This pic shows it before I begin,
and with the wheels removed. During this project, it is also a good
time for a good cleaning of any off-road grime which has
accumulated, check for any loose hardware, and damage which
needs repair, and a time for a good oil/grease where needed
Image
Next step is to prepare to remove the steering linkages and all
suspension links. Depending on your truck these may vary
somewhat, but should be similar.
Image
More linkages to be removed, along with the pivot bolts. Hint: If
you sometimes have trouble remembering how things fit back
together, take some pics with a camera, make sketches, or even
use a camcorder. It will give you an instant reference on how
everything fits. (Not that I have ever had this problem!)
Image
Now you can see the steering links and pivot bolts removed. Next
the wheel hubs have been removed. I find it helpful, after removing
any nuts or washers from a bolt, place them back on the bolt in the
same arrangement they were removed. It keeps everything together
and less likely to lose any small parts.
Image
More linkages removed. Finally after removing everything
necessary, the axle is free from the truck (Note! I missed getting
any pics of removing the motor and servo mount. They share the
same mounting screws, so it is pretty straightforward.)
Image
Now we are ready to open up the axle housing. The screws marked
"a" are the ones we need to remove. The sleeves marked "b" are
what the motor/servo mount screws pass thru. Use caution when
opening the case up as these sleeves are a tight fit thru the case,
just go-slow and you won't have a problem.
Image
Now the case is open, we can see what we will be dealing with.
Image

8) 8) Hay Unruely and Krod Clod,(if your still out there!) I just want to inform you that JB Weld really works..WoW 8) :biggrin: ANd mind you that this is the very first time I ever in my life using this product!

A friend of mine had better luck with adding hot glue to the spidergears to "lock" the diff. He said it took him 10 minutes and the glue dries a lot faster than JB weld.

It's also reversible without damage to the gears if you so choose. JB Weld is forever and you'll have to replace the gears if you want to go back.
I used to think I was indecisive, but now I'm not so sure.

I understand,but with the Max power of high top speed that the 15x2 motor,and what ever size pinion I will use I don't to take the chance for hot glue to brake.

The Hot Glue works reel good,I used it on my 6x6 Puller,the
truck Weighed in at 20 Pounds,3 motors,14 Cells,I
was Pulling 125 Pounds out the Door with Hot Glue Diff Gears but if you want to use Grease then you can't Hot Glue them,the Grease will loosen up the Hot Glue.Jim

I'd also recommend going with hot glue.

I locked both diffs on my stock clod as I was assembling it for the first time, it was horrible. It would kind of steer on dirt, and was un-driveable on pavement. I'm sure axle mounted steering would have been the trick, but my clod was dead stock.

After a few runs I decided to try un-locking the front, and it certainly wasn't easy, but I was able to pull the gears apart, and scrape most of the glue out and re-assemble it as an open diff. It was better, but still terrible, and still un-driveable on pavement. I finally ended up unlocking the rear, and am very happy with how the truck drives now.

the hot glue did work, I only had it in there for maybe 10 runs, but no signs of coming apart, and I was able un-lock both diffs.

I also sure as crap don't recommend locking your diffs without axle mounted steering.

the best way to me is to order from bizzare hobbies, 2 hot racing diff locks will cost about $34. it is a lum made and high quality.
here is pic of how it looks in my gear box. the glue method is taking a chance, i would rather just spend the money and get a good quality locker.

Same for me, I put one of the Hot Racing locks in the rear. I'm thinking of putting one in the front as well.
