original TLT rock buster

[frank400]

Hello everyone its been a long time since a lot of rc went complete RTR and not kits. My daughter found my pretty much original taymia tat rock buster in my closet and wanted to try it out. so i only had a cheap charger now so we charged the flat pack and installed fresh batteries in remote it sprang to live like new. she was running it in my garage for a while making little obstacles when all of a sudden stopped moving unless you picked it up, once you put it under load nothing you see transmission spin but nothing. do you think trans went or a diff?? thanks for the help...my daughter really wants to trick it out like some of my others I had years and years back.

There's a center ball differential inside the trans, sounds like came loose and is slipping. Tighten it back up with a 1.5mm allen wrench and it should be good to go. Should be a simple as popping off a lower link and removing the dogbone to get to it.

If you really want to set and forget, replace the diff balls with a set of Traxxas Rulon pegs. (PN TRX4685) and put some red threadlock on the center screw. It won't slip or come loose again.

Thank you just to confirm would that be from the rear side heading to rear axle??
Thanks again
