While wheeling in Big Sur the last 2 days ( ) I developed a brand new squeak in my rear suspension - most easily noticed if I step on the rear bumper. Going underneath it seems almost certainly to be something connected to the upper control arm. I'm guessing this is related to the insane amount of dust I went through, but unfortunately there's no way to grease the "for life" components if they are now dirty.

What do folks think of the following options:
- Mopar replacements ball joint and bushings and hope they don't go too soon again.
- Greaseable aftermarket parts
- Installing a zerk fitting on existing or new Mopar parts?

Other than the squeak, the ball joint seems fine... I think... no obvious play. I'm at 80k in an '07.

Thanks for the input!
