Newbie with EzGo ST480 Questions

[904polarized]

New to the site here and have a couple questions regarding a 2004 EZGO ST480 i recently purchased.

The cart feels like it slips in and out of gear sometimes. I will be taking off and then the engine will rev followed by a clunk and then it grabs again. I did a search and it appears that my drive clutch might be sticking. How do i go about cleaning/un-sticking this drive clutch?

Second issue. My locking diff doesnt work. I can shift the lock/unlock lever at the console but nothing happens. It has the cable attached at both ends but nothing moves (cable inlcuded) when i move the lever. Do i need a new cable???
Also, if i manually grab the lever at the rear end and push up on it, i hear/feel a click. Does that mean the diff is engaged? It will only move about 1/2" up. When i let go, it falls back down. Does this seem normal?

Sorry for the long first post but i need some help!

Thanks in advance

Sounds to me you need a new cable, try holding the diff lever and rolling the cart, most will not go into lock until one or both tires start rotating

Anyone have some insight to the drive clutch? I did a search but couldnt really get a clear answer

More than likely you need a new diff lock cable. The arm on the transaxle will only move about a half inch. It slides a collar over the end of the axle to lock it. As far as the clutch goes I would have to say a cleaning a little lube and some new slides and you will be good to go. Hope it helps.
