Driveshaft u-joint hitting exhaust pipe

[Rubistang149]

Hello,
Every time I would hit a big bump, I would hear a bang. After looking under the jeep I found the u joint hitting the pipe. Anyone can tell me why this happening and how to fix it? I would greatly appreciate. See pic. ps My shocks seem fine. Nothing is leaking

Stop hitting big bumps.

That’s about the only feedback you will get since we know nothing about your rig. Fill out your profile and tell us about your specific setup.

Common causes are the front axle being off center due to a lift installed without an adjustable trackbar or not centered with an adjustable.
Minor front end impact which bent the trackbar pushing axle to the right side off center.
Exhaust manifold/header loose on the collector flanges allowing it to droop and cause interference with the pinion u-joint.
Some combination thereof.

Had this same issue years ago. Loosen the exhaust from the manifold, reposition it, then cycle the suspension to verify if the issue has been resolved. If that doesn't do the trick, as Blaine said, adjustments may need to be made to track bar to center/move the axle housing.

Awesome. Thank you for your help.

Thank you. Will try that

My stock '98 is having the same issue. Started after I swapped the frame with an '06 frame. Something I can check myself, or can an alignment shop address it?
