Speedo and tach drop to zero

The speedo and tach will drop to zero on my 98 4.0 then return to normal. It does not effect anything else. Any suggestions?

It's a loose connection on the plugs on the back of the cluster. Some times it will also go to the smaller guages.

Remove the cluster and push the pins on the back all one direction a millimeter or 2 and it will stop... Or just slap the top of the dash like I do and say "bad jeep"

You can also turn the lights on and off really fast or hit a big bump. That's what I did till I got it fixed

Just what I was hoping. And yes I have already beat the dash a few times, the bump works well also.

Thanks
