    Mine does this too, but only when I let off the gas at any speed above 45mph. It is something to do with the slip yoke and my lift. I've put 10,000 miles on it this way and just live with it because i don't have money for a slip yoke eliminater kit. I just apply the brake before letting off the gas and the growl goes away.

    Is yours lifted at all? Mine does the same thing when I let off the gas over about 25mph. I just have to power brake it to a stop. I have a shackle flip and 1 1/2'' blocks on the rear with the stock drive shaft. To fix the problem on most lifted K5's you dont necesarily have to get a slip yoke eliminator, most of the time a c/v rear shaft will do the trick.

    IMO you need to have your transmission checked. I had an identical situation in a Suburban once and it turned out to be the torque converter.

    I also have an 89 Jimmy with a 6 inch lift that does the same thing above 50 mph. Has anyone tried a rear CV shaft without the Slip yoke eliminator and had good results? Where is a good place for purchasing these?
