Why does my KJ squeak when parking ie. backing up and going forward?

What do I need to grease?

check the ujoints, they maybe toast,
if so they are fairly easy to replace just make sure you get good ones that you can grease

Tom, help me out. How do I check them? When driving, you can't hear it but standing outside while the KJ is being parked, you hear mild squeaking. It feels tight with no issues so just curious what I should inspect?

Thanks
