Driveshaft shake?

Alright, well i just took out my driveshaft everything looked good. The tailshaft was totally smooth and the u joints were good. I've been looking for the tailshaft bushing though just incase it is bad on murrays website and autozone but don't know which are the right ones. If somone could take a look for me and post the link that'd be nice. Thanks guys.

I can't quite picture this tool you refer to... Do you have a photo or a link? Not common enough for rental I guess...

thank you ryan. Will probably pick that up tommorw. Hopefully they have a rental tool too.

Thats why I'm here right? lol

Lemme know how it turns out.

Alright this might sound crazy but I think i figured out what it is. About a month ago I put 2.5 inch exhaust on my car. I had rubber hangers and they ended up snapping off. Luckly it was sitting on the bar that the Parking brake goes across on. So I rigged something up and drilled a bar that went across the drive shaft so I could mount my exhaust. Well i bought a new hanger (A better one that was all metal except for the rubber that made it a 360 swivel. Well it was too big so i decided i'd make my own out of a piece of metal. i drilled a hole threw that mount i made mounted up my new homemade hanger and bolted it on connecting it to one of the exhaust clamps. The thing was so sturdy and my whole exhaust about didnt move. I'm thinking that the engine since its shakes when moving that it shakes my exhaust which is making the rumbling noise. I'll have to take a picture for you guys. I bet thats the problem what do you guys think?

Update::: I just unbolted it and put a new hanger on the back. Took it for a quick test drive and it didnt shake anymore. I'll post some pic's tommorow show you what i did that made it wrong. I thought it was clever like Mcgeyvor or something. Guess not lol.
