Spunkymunky88 Posted February 3 Share Posted February 3 (edited) I have a corally jambo that I have had for about 2 years back end of last year i replaced all my drive cups to the spring steel options as i did that i changed all the dog bones since that happend there has been slipping during acceleration The meshing is perfect checked the centre diff also had it at a couple of local modelshops and they cant identify where the problem is but i cant get the car to perform like its meant to because its slipping when you put the power down anyone got any ideas what it could be I am running it on 6s Edited February 3 by Spunkymunky88 Quote Link to comment Share on other sites More sharing options...
locky Posted February 3 Share Posted February 3 Can ypu explain what slipping looks or sounds like? Did you have the diffs apart to change anything? Does it do the same when accelerating with wheels off ground, ie. no load. Quote Link to comment Share on other sites More sharing options...
JonnyUK Posted February 3 Share Posted February 3 Is every grub screws tight on drive cups, axles etc? Quote Link to comment Share on other sites More sharing options...
Kpowell911 Posted February 3 Share Posted February 3 (edited) Whats slipping? Is it wheelspin? IF youve got no issues with the diffs, look at the wheel hexes/grub screws Edited February 3 by Kpowell911 Quote Link to comment Share on other sites More sharing options...

I will try running it on my stand with no wheels on see what thats like it sounds like its a gear slipping somewhere under acceleration Quote Link to comment Share on other sites More sharing options...
locky Posted February 5 Share Posted February 5 It could be the grub screw coming loose on the drive cup which attaches to the gear meshing with the diff, just enough for some drive but slipping under full load. I've had it happen. Quote Link to comment Share on other sites More sharing options...
Candyman Posted February 5 Share Posted February 5 Jam something in there to stop the center diff turning at all, then try to turn the front wheels over by hand and then the rear, if you can get them to "slip" follow the movement from wheel, to driveshaft, to drive cups, to diff, to prop, etc to identify where its breaking down. 1 Quote Link to comment Share on other sites More sharing options...
Spunkymunky88 Posted February 25 Author Share Posted February 25 Update on this opened up the rear diff today and there looks to be shards of metal between the crown gear and bevel gear so heres where it must be slipping For reference when i replace these in this bevel to crown is it supposed to be lubricated if so what with Quote Link to comment Share on other sites More sharing options...
