Hey I got the transmission mount installed and it's still making the thump. When I watch the video I made it seems like the thump I'm feeling is coming from the transfer case moving. I was under the truck today messing around with some things and I noticed on the driveshaft there is some play in it where it goes into the transfer case. I made a video of it. Could you watch it and tell me if the driveshaft is supposed to have that much play in it. The thump is really getting on my nerves and I don't really know what to look for. I did try greasing the slip yoke but it's still doing it. Thanks.
