So to avoid the front driveshaft issues just change the ujoints or? Is it a mileage or age thing?

You can get a replacement OEM front driveshaft for cheaper than the ujoints. I just tossed a new one on ~6 months ago. Plus it takes about 5min to swap a front driveshaft vs over an hour to deal with swapping all three ujoints.

I replaced mine because they aren't greasable and they started squeaking at me. I'm at about 200k and get car washes w/ underbody rinse all the time (like every other day).
