Grease off drive , on exhaust

[T Y L E R]

I've been poking around under the 80 looking for that burning smell . Its almost identical to the smokey smell after you get a vehicle undercoated .

Anyway , I notice there is grease from the driveshaft that has been thrown onto the exhaust system . That must be the problem .. just not sure why it waited so long to occur .. I had everything lubed in early Sept.

Could this behaviour be a symptom of some breakdown within the drive shaft ?

Ty-

If you're slinging stuff from the drive shafts, you'll not only get it on the exhaust, but you'll see a nice ring-around-the-underside effect going on. If you're not seeing that, then I'd eliminate that from the possible sources and move on to/back to the engine area.

PS: I new you'd know the Sesame Street song

I get that after every greasing, it's normal and not any indication of a failure.

I think it's 'normal'. When you grease a u-joint I believe you should pump in enough grease to fully push any old out, so you see the new actually coming out. This ofcourse makes a huge mess on the u-joint, which I usually try to cleanup with my fingers/rags, but you never get it all, and some is always thrown around in a ring. The exhaust is a favorite place for it to land. I don't know any way around this, except for maybe stopping putting in new grease when the old just starts to come out, but IMO that doesn't fully 're-grease' the joint, which is why you are putting grease in it in the first place...so not sure what else you could do...anyone have any ideas?
