1998 Sahara

[Seanyd]

I'm sorry if I'm in the wrong forum but My 1998 Jeep Wrangler Sahara keeps jerking when I'm driving, not really so much when I'm accelerating but when I don't have the gas pushed down too far.
Things I've done or replaced:
-standard tuneup
-new feul pump
-o2 sensor
-throttle position sensor
-crankshaft sensor
Does anyone have any other ideas that I should try?
Thank you!

Check the rear u-joints.

Thank you, guys I appreciate it! Now that was mentioned I do hear a little clicking on occasion. It felt like it was a fuel issue but you think that could be the problem?
