I was crawling about under my truck earlier this week (as you do) and noticed some play in the rear prop slip joint.
So, out with the grease gun and gave it a couple of pumps, check the play and still there. So, another couple of pumps, check play, still there. In the end it must have taken about 10 pumps to eliminate the slight play.
Now this got me worried, I tend to do that a lot following our accident I always see the negative in everything these days.... sorry got side tracked there. Anyway, I convinced my self that I had eliminated the free play by causing a hydraulic lock so, off came the prop. I was expecting it to force the slip joint apart as I did so but that didn't happen. It moved freely albeit with some resistance due to it now being packed with grease.
Question is.... is it possible to over grease a slip joint and cause damage to either the rear diff pinion bearing or transfer case bearing? Obviously the prop is continually shortening and lengthening as the rear axle moves up and down, just wondering if the situation could ever occur where too much grease could actually make the prop effectively rigid?
