I took my Yukon in to get the rear driveshaft UJs replaced and then balanced. The shaft was squeaking like a pack of burning rats and there was a definite vibration developing through the chassis. Dan's did exactly what I asked for without the usual Vegas up-sell of stuff that is not required. These guys do great, honest work at a very reasonable price ($150 all in). My truck is now even quieter than a mouse and runs as smooth as rubbing honey on Kiera Knightley... not bad for 220,000 miles! Thanks Dan's!
