my diff comes lose every time i run my car i have to retighten my diff cna any one help[]

I have the same exact problem...In my thrust balls i only have 2 out of 6 in there i have others to put in but didn't have time...Also when i hold my slipper with my left wheel held and spin the right i hear a grinding noise kind of is that because I'm missing 4 thrust balls?

i have all the trush balls i greased everything last nightbut it keeps coming lose[] im going to tightenit more right now

i went and put in the new balls and everything seems fine its 10:30 at night here so after church tomm. i will be running it...

ya but i dont know why it comes lose i tighned uo im ging to look at it after dinet

how do you know/tell it keeps comming loose?

the truck dosnt move the the tranie spins and that iv rebuilt it 3 times i understand how the diff works the slipper gear i cranked it up to test the diff

1st the truck reves high but it hardily goes anywhere
2nd loss of top speed
3rd hold the slipper and disengaged the brake and try to tirn both tires make sure the slipper/sper gear dosnt MOVE turn both tires at the same time thats it slipping if its hard to move the tires but they move good if you cant move at all loosen 1/4 of a turn if they spin freely you will burn the diff in a hart beet

this only goes for the evader i don't know what others do

ya i relooked at it nothing rong? as i can see i will run it next week its raining[] this was my week off 2

The nylon nut that holds the diff together may be worn out. Replace it, threadlock it, or both.
