98 ZJ 4.0 stock except for a 2" BB.
I have a loud grinding and clunking which sounds like its coming from the rear. The sounds seem to happen when coasting between shifts.
At 14 seconds you can hear the clunk and see the RPMs drop fast, it happens when I let off the gas right before it shifts. http://vid.me/bMtV
I think its shifting after the clunk happens? It hangs onto 2nd gear and clunks if I let off the gas when the RPMs are max right before it shift.
Here you can hear the grinding noise. http://vid.me/GLmT
When its grinding like that the Jeep will slow down pretty fast like I'm braking.
The grinding happens when I left off the gas right before it shifts into 2nd.
After it shifts it coast just fine until it gets back to 1st gear and it starts over.
This is my first vehicle but I've done all the work on it myself so far so if there is anything I can try or look at let me know!
Thanks for the help.
