The pinion gear is skipping over the ring gear. [link=http://www.monstergt.com/articles/transmission_diff_shim.php]This[/link] is the fix

I've had the problem in the past and pictured below is what happens if it goes unchecked. Since shimming i've had no problems whatsoever.

so i can to buy new pinion or to do this Process?
or if ill buy new pinion it is not good and i need only to do this Process?
i ask it because i dont have how to short the cap...
thank you.

From the look of the pinion you can do this process without buying a new ring & pinion set. It is however recommended for ALL diffs, whether they are new or not (they are not shimmed properly from the factory, it's not something that develops over time).

To shorten the cup you don't even need digital calipers, just file away until it fits

i think the same thing has happened to my t-maxx, front diff,,, i use i high torque servo for my brakes,, and everytime i hit the brakes i get this loud crakling noise from the front diff,,,, will shimming it solve my problem!! thanks,

i also checked if my diffs were worn out just by holding the rear wheels tight and turning both fron wheels,, after a certain amount of force was applied the diff started to skipp!!

what should i do??

How worn are the ring and pinion gears?

matanmax

You have pic of thw pinion, i think he look good.
the ging not look worn and i dont have pic of the ring..

If you've shimmed it properly and it's still clicking it's probably be too worn and needs replacing.

You have checked it's not the other diff that's now clicking haven't you?

matanmax

no, its not the front is ticking..
when i push the rear wheels and stop the front its ticking(the rear)
when i push the front and stop the rear all good.
the problam that i cant buy new diff, in my country they dont sell parts for MGT..
