Squeegie Posted April 7, 2018 Report Share Posted April 7, 2018 Hello everyone. My 2003 ss AWD have started to do a very nasty sound when i launch it hard, Or hold break and gaspadel at the same time. it slams,clonks and rattles almost like a drive shaft is slipping but cant see anything odd with them when i lift the truck up on a lift. any tips?

Rholston Posted April 7, 2018 Report Share Posted April 7, 2018 I seem to have something similar when i go from reverse to drive. It feels like there's slop/play in the u-joint or something. Quote Link to comment Share on other sites More sharing options...
EXGM Posted April 8, 2018 Report Share Posted April 8, 2018 A loooong time ago GM issued a TSB for an updated yoke to address the clunk. Could be a bad u joint as well.... I would check to make sure they are ok. Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted April 8, 2018 Report Share Posted April 8, 2018 If its a popping noise everyone is wrong and I can assure u its the chain in the transfer case skipping teeth. I win! Quote Link to comment Share on other sites More sharing options...

Blown 346 Posted April 8, 2018 Report Share Posted April 8, 2018 You have to open the t case up. Quote Link to comment Share on other sites More sharing options...
Doughty08 Posted April 9, 2018 Report Share Posted April 9, 2018 If the truck is only popping under launch and maybe decent pulls off the line and does not do it cornering or under normal driving conditions the chain has stretched inside the case and its time for a case caver, chain and if your inclined whatsoever with a set of tools do a full rebuild while your in there which is pretty sraight forward with these transfer cases.
