Unlock rear diff Can anyone help me with part list to unlock the rear diff? I like to make it corner better. |
Re: Unlock rear diff i dont know but maybe just maybe a exo terra diff might work. dont knw for sure though as most axial owners dont really like unlocking anything lol its more of how do i lock this or that.. |
Re: Unlock rear diff Same parts, as per your manual, as the front. If you don't have your manual the instructions are on the axial web site. |
Re: Unlock rear diff Check out this thread. It's not as simple as putting the front diff into the rear. http://www.rccrawler.com/forum/axial...my-wraith.html |

Rubbish It's precisely as easy as fitting a set of the exact same spider gears/pin/orings to the diff cup in the rear as in the front & filling with diff fluid of your choice, on my 2.2 U4RC rig it's 1mill wt Mugen gel. That post you linked says nothing different. |
Re: Unlock rear diff I stand corrected. For someone reason, I thought you had to modify the shafts to fit inside the diff. Like in the front, the outdrives are C clipped so they don't move. Sorry for any confusion. |
Re: Unlock rear diff How do you go about filling the rear diff with fluid since it doesn't use the same sealed output shafts as the front? |

Re: Unlock rear diff I agree, it's not that simple. That's why I questioned the advice in the first place (see post #4 above). Take a look at this post, start reading at #82. http://www.rccrawler.com/forum/axial...al-yeti-5.html EDIT: Take a look here as well. http://www.rccrawler.com/forum/axial...-rear-end.html Same problem as you described, but with a workaround. Not ideal, but you can make it work. |
Re: Unlock rear diff Hey guys just wondering what oil would be a good starting point for unlocking the rear diff. I hear some ppl using 500k but it sounds like that would pretty much lock it. Anyways would be good to hear what you guys are using. |
Re: Unlock rear diff 500k still offers plenty of play. I had mine unlocked but both outer o-rings kept breaking due to how the rear axles sit, this caused all of the fluid to leak out after a couple of sessions. |

Kinda like this; http://i1310.photobucket.com/albums/...ps5wny2chp.jpg While not a ideal design with the Axial straight axle because of the flats in in, it should work with thick enough diff fluid. |

Re: Unlock rear diff Part of the sealing effect is the oring, washer and back side of the side gear. I can see where there would be a issue trying to stick it together with fluid coming out while your trying to stick the axle shafts in there. Unless there are side gears that are not machined all the way through, for this application. I'm used the the gear diffs in Short Course trucks, the outdrives get pinned in there essentially sealing the diff. When I ran Durango, I had 3 assembled gear diffs with different weight fluids for different track conditions. |
Re: Unlock rear diff Here's a pic of the SCX10 open gear diff, it anyone needs part numbers or anything..... http://i1310.photobucket.com/albums/...psrgcwkcpq.jpg |

Thanks for the info. EDIT: How well will the grease work instead of silicone diff fluid? Would it still be "locked" if the grease is thick? |
This is the exact same situation I've been trying to figure out all morning. The only possible way I can think of to fill the rear diff with oil is to have one axle inserted, and use some type of mini hose (or long enough syringe) to inject/fill diff housing from the other side. My next option would be to possibly try some Bad Horsie Diff Locking Grease. Description says..."creating a limited-slip-like feel". |
Re: Unlock rear diff What weight diff fluid are you guys trying to use? Cos the 1mill weight Mugen gel I have in mine doesn't run & you don't pour it, you scoop it, use a popstick or plastic knife. By all accounts from the guys here the ½mill is still a similar sticky gel. The guys here are using either of the above 2 gel in their Yeti, mine is in the front axle of a U4RC 2.2 trophy rig but the axle goes together exact same as Yeti rear. Green slimed o-rings & gasket same as doing shocks. Assembled with the just o-ring under the spider gears, drop the bottom gear in the cup, scoop gel in till its all but full, sqeeze the cross shaft & side gears in, push the other spider in & used the axle shafts to keep the gears all aligned while I screwed the ring gear down, pulled the axles out, dropped the centre in the housing & put the axles back in. Nothing comes out while the axles are out, takes barely a minute to pull axles, drop in centre & put axles back in, you can do the centre bearing caps after the axle is in. Been through 2 u4 race days & its still in there. |
