My tailshaft housing in my a4 keeps F ing up. I have changed the stock one which had a nice hairline crack from the middle of the left side, down the bottom, and back up to the middle of the right side. I changed it and put about 200 miles on it. Then, i pull into my garage today from a drive to the gas station and there is a huge puddle. I look under my car and there is a nice steady stream of fluid comming out. What do i do? The tailshaft i replaced the stock one with was used. It didn't appear to have any cracks in it. Is there a stronger tailshaft housing i can buy? Are there any other possible reasons for it cracking? i have DR's and the rest of the mods in my sig. I honestly have only done 1 nice burnout since it was installed. Other than that i have not been shocking the drivetrain at all just WOT's at speed excess of 40mph occasionally.

Any feedback is good feedback!

 

This is a subject that is discussed here frequently... at least a few times each month. To do a search would be useful.

I am going to go out on a limb here and guess that you have a polyurethane transmission mount, and possibly poly motor mounts. If so, install a rubber mount, similar to the factory original mount.

This condition typically occurs at high rpms, highway blasts. It is not uncommon at all.
