I need to know how to rebuild the ball diff. Or better yet does anyone have a complete diff. or gearbox laying around?

Thanks: Clint

Take some tools and go at it.Only way to learn.

It's not hard to do. If you have your owners manual the exploded diagram is in there along with instructions. If you don't have the manual then Duratrax has them online. When you take it apart be careful, those "balls" are tiny.

Here is the rebuild kit

You can get the instructions in the evader pro manual on duratrax's website

If you don't like that price I will sell you my diff just rebuilt.

How much do you want... just wondering

duneslider

Really I was more kidding. Trannies go for about thirty with shipping on ebay. The rebuild kit goes for seven. Why buy a new one? Why do you think you need to rebuild your current diff? What problems are you having?

Well i was out bashing in the yard and it just stopped, Not the motor just the truck. Like the gears turn but not the wheels.So i took it my LHS and they told me that the diff. was slipping and I need to rebuild it. Well here I am.

DaveG55

Pull the tranny out, take it apart and look at the gears. It really sounds like it may be a stripped idler gear (the middle one) rather than a bad diff.
Just my thoughts.

OK I will check that tomorrow

duneslider

Check your slipper too. They have a tendancy to loosen up. I can't imagine the photon speed stripping the idler gear. It could happen though. Make sure the slipper is properly tightened and in good working order.

Do you have the pro or regular evader?

checked them both, I'm tellin ya the diff. is slipping. I no longer run the Photon moter It is a Tram Orion 14x2 turn with a Novak Cyclone ESC. I have had this thing radared at 30 MPH.

raz54

Yeah it sounds like it's slipping cause it should be faster than that. Have you tried adjusting the diff with the allen wrench to make sure it didn't loosen up?

yep it's as tight as it could be

I think i am having the same problem as Crash 81 10 . i have a gtb 5.5 in my st pro.

How do you know if it is the slipper or the diff.

I took everything apart and since i am not a pro i cant tell if there is anything wrong with the diff or not because i never had reason to open it while it was working properly so i dont know how it should look.

it does look rather dry where the bearings are. So when rebuildong do you just take all the bearings out and clean everything or do i need to buy that rebuilder kit

and start over?

Warfield, I am sorry no one can help us. If you find out tell me and I will do the same

duneslider

Yes you should use the kit. Usually it is just the rings that seem to wear out. The whole kit is cheap and you know it comes clean and lubed. Seven bucks isn't bad. Also, that spring can wear out and not hold it tight enough.

Check out this link and read the how-to on adjusting the diff and slipper. The evader diff can sometimes be a pain to get it adjusted.

Also, did you rule out the idler gear? When you open up the diff you can easily tell if the idler is bad.

The diff shouldn't be totally dry, it needs to be lubed. Most use the white grease.

yea the idler gear is just fine

Crash 81 10

My Feedback: (1)

ok so I found out i need a complete new diff. anybody got one

raz54

Why do you need a "complete new diff"? Can't you rebuild yours? I just took mine apart for the first time today cause it was making a load rattle sound. The idler was stripped is all so I have an aluminum one coming for it. You may want to put one in too if you are running a hotter motor.

duneslider

So, how did you come to that conclusion? There is no reason I can think of that would make you need a whole new diff.

I need everything except what comes in the rebuild kit, which i already bought. so therefor i need a new diff

duneslider

Why do you need everything except what comes in the kit. The top shaft is nearly indestructable. The idler gear should be fine (because you said it was) but a new alum. would be a good upgrade. The bearings should all be just fine. The tranny case, if broken, is only a couple bucks. So, I ask again, why do you need the whole entire tranny? The only problems you seem to have are with the diff. Which the rebuild will fix. Maybe you should explain what is wrong.

Duneslider

fugaziiv

I have to agree with duneslider. From this thread i can't figure out why you would need a whole new diff instead of a rebuild...

because I already have the kit. Never mind someone had one for sale at the LHS so nevermind anyway

hey raz54 where did you get the aluminum idler from.

thank you.
