Get to Toronto unload the van and after a quick stop for coffee I headed for the 400 southbound. As I got past 80km/hr I didn't like what I was hearing... I could hear a distinct loud grumbling noise from the back. If I was below 80 you didn't really hear it.
Got back home and decided I had better see my mechanic about it.. turns out my gut instinct was right, it had a bad rear u-joint. The shop wasn't busy so they asked if I had time to wait while they put the new one in. Got the right part but they were having a hell of time putting the new one in.
The upside is that I brought it in now instead of being out in the boonies somewhere and having the driveshaft fall off.
Hopefully I'll have it back today sometime.
