    1997 Tahoe 4x4 with 3 inch body and 3 inch blocks and cranked to level. So from take off or at just rolling speed 5 mph or less I get a rythmic squeak squeak squeak. I pulled the drive shaft out of the rear yoke to find a stuck cap but the squeak or squeal still exist when I turn the drive shaft with it only still connected to the transfer case which leads me to believe it isnt the rear u joint. Not that it couldnt use replacing. So with drive shaft as straight as possible and disconnected from the rear end when rotating the direction that would be forward the sqeal squeak is still there. I find it hard to believe its the front u joint with having perfectly straight on with the transfer case so no flexing really. Makes me wonder if there is a bad seal in transfer case or low on fluid causing sound. Sounds seems to come from inside driveshaft which I know is impossible. Any advice. The searching here and there has all pointed to u joint but need to know that Im not replacing the wrong parts.

    Not that pics of the truck were requested or help with this situation but since this post will show up in search results might as well give and Idea of how it looks with the small lift it has. BL blocks and Tb crank.

    Re: 1997 obs tahoe driveshaft area squeak

    Going to be doing that my grease guns junk so might get a different one or replace them. Now this is probably unrelated but I have a rear end wobble at around 65-70 and up. The weird thing about it is it seems to do it when I go over small dips in interstate or as you aproach the seam of an overpass. Hope fully that make sence. That makes me wonder about rear shocks to fix that but also read something about wieghts on the dums causing wobble. Really concerning and I have rechecked the ubolts so many times after the blocks were added and They are tight as they can be. Could be tires also the wheels and tires are very very heavy.

    Well made a trip to tire shop today and had rear wheels rebalanced and problems gone. No more wobble in rear had it up to 90 and nothing. Pretty happy. Also got a driveshaft today from the local ewe pullit since the places around here that do u joints arent open on weekends so 20 bux for this driveshaft and when all said and done it will end up a spare for me and some buddies.
