So my passenger side halfshaft is squeaking, and it's been getting progressively worse over the past month or so. I know it needs some work, so here's my question: Can I just punch a pinhole in each of the boots and PB Blast the crap out of it? Or should I just replace it? I know I'm probably gonna get barraged with a bunch of posts tellin me to replace it, but over the past two days my friends and I just did the tie-rod inners and outers, a lower ball joint, and a hub/wheel bearing assembly, and I really don't wanna take my truck apart again. Saving the extra couple bucks wouldn't be bad either. However, I do wanna fix my truck, even if I have to rip it apart again, so please let me know what you guys think. Thanks.

 

Probably shouldn't have posted this in the middle of the night sooo.... bump

 

The hubs seals on 98+ 4x4s have been known to produce a high pitched squeal when they get dry or dirty. I don't remeber hearing of a fix for that. If the half shaft itself is squeaking, I would replace it.
