| What are these grub screws for?
Sorry for this possible stupid question. Not far into the build,i am waiting for parts. The front diff case has 2 grub screws at the rear,the manual does not state how far to screw them in,then 2 more are required in the bottom of the rear axle. I have looked further into the manual and see nothing attached to these.The holes are not through holes,they bottom out. What is the purpose? |

Take a look at the gears and see if the grub screws in question, are for securing gears to the axel. If so they would be ran in until they stop. As for how tight, IDK that answer. Hope that helps.

the rear axle has the holes so the axle can be fliped and the truss mounted on the other side last i remebered they went all the way through and the grub screws were used to plug the holes so dirt dident get in the diff cup that the ring gear bolts to has a grub screw to blead air out of the diff during asembaly they just get screwd in till there flush i have no idea what there used for in the front diff housing though probably just set them flush also ive never opened the front diff on my little yeti just the xl so im probably missing something pics of the issue always help Last edited by ferp420; 12-09-2019 at 10:42 AM. |

As stated above, grub screws in underside of rear axle simply close off surplus holes where truss would attach if housing was up the other way. In the front diff housing again they close up surplus holes, the case is a hang over from the EXO buggy & on those a suspension toe plate attached to the housing with 2 screws into those holes, on the Yeti that toe block is built into the front of the chassis so holes are open & could let in debris. |
