well, south louisiana is taking its toll on my yotas. Recently my tacoma (just shy of 100k miles) has developed a squeaking noise somewhere in the driveline. The noise is most noticeable while backing out of the driveway and while moving very slowly forward. Today I took apart the driveshaft and replaced the center support bearing that seemed pretty worn. All of the other parts of the driveshaft seemed very tight, no play in any of the u-joints or at the t-case/pinion gear. After replacing the center bearing, the noise is still there. Anyone else out there encounter this problem or any suggestions before i start spending money on things that are unnecessary (center bearing cost me $220)

 

When was the last time u-joints were greased?
