vehicle is a 2004 chevy tahoe 2WD. tranny fluid sometimes leaks from slip yoke. had the output shaft seal replaced and it still leaks.pink fluid drips from the yoke/ujoint area anyway not even from the seal.car shakes at 60-70 and little humming from back of car. ive had a u joint go bad before and this is different, noise is different and doesnt violently shake my car like the u joint did, instead it just shakes it slightly. this is also a new driveshaft/ujoint i have installed right now, we didnt change the yoke so i guess that gives me my answer but im just wondering what yall think… ---

My guess, the entire driveshaft ass’y needs to be re-balanced. The leak may go away once that is done. Visit a shop that specializes in driveshafts. ---

With a new U joint the yoke should be OK. ---

Maybe the tail housing bushing in the transmission is worn out. That would allow the yoke to flop around, cause vibrations, and leak even with a new seal. ---

Let me second @ok4450’s diagnosis. That sounds like the problem to me, too. It would explain both the leak and the vibration. ---

How big a job is replacing the bushing? ---

An aggravation if yout don’t have the bushing removal tool. Lacking the tool it’s best to remove the tail housing which is going to mean fluid loss. That bushing tool is a bit pricey but there may be some cheaper alternative tools out there. Here’s what it involves and the tool.

Yes, just have a shop do it. I think the tool in the video is about 160 dollars with some at 250. Ouch. Worth it for a trans shop; not so much for a DIYer. There is the tail housing removal method if the OP wanted to go that route. Then it would be a matter of making or buying some press sleeves to take the bushing in and out. Not worth the hassle IMO. Such is the mechanic life and perpetual tool buying. ---
