Is this rubber gromet critical?

Man, trans project done, and shifts v nice. Cleaning up garage now, and found this blk rubber gromet hidden. I forgot to place it on output shaft, just behind the nut, and, I believe, in front of flex "donut" joint on driveshaft. Should I undo the rear part of the driveshaft to put on? Im soooooo tired of trans work........LOL! (in photo, I have 2 shown....one on the shaft, and the spare one.

Peruse this thread and decide.

Yes, it goes there and serves two purposes: (1) acts as a stop to keep the front driveshaft piece from bashing forward, and (2) acts as a grease seal for the grease you should put in the front driveshaft bushing piece where the ball/olive fits.

This goodie is slightly pushed up against the trans output yoke by the front of the driveshaft as you tighten down the donut bolts. There is no zerk fitting; you just put grease with your finger on the bronze bushing in the front of the driveshaft that the trans output shaft ball/olive fits into.

I doubt it's a problem. I have found them missing, and these bushing get lubed pretty only when the driveshaft is removed, so they run relatively dry, probably, most of their life.

You do want to check the fit of the ball into the bushing, and make sure the ball is not pounded flat or out of round, all of which can lead to vibrations.

Update: Finally put in thaT bushing, and filled that hole with grease. Man, was that a dumb mistake on my part.....forgetting to add that one little stupid bushing when I had the trans apart, mounting it all back together without it.

Anyway, reason for my update was to also let yous know that, although I was a little apprehensive in not doing this right away, ended up I did this with about 700-800 miles on the drive shaft, and luckily, no problems with damaging the tip of the 3 prong fork. Whew!
