41chevy Posted March 22, 2017 Share Posted March 22, 2017 (edited) Rear tires for belt separation or odd wear and than look close for worn universals, bad carrier bearing,a loose or worn drive shaft yoke or a biding or worn slide joint in the drive shaft. Those would be the first things I'd look at.

j hancock Posted March 23, 2017 Share Posted March 23, 2017 Is it air ride? If the pinion angles get screwed up because ride height has been changed, it can lead to vibrations. 1 Quote JimIt doesn't cost anything to pay attention.

Elitedownunder Posted March 23, 2017 Author Share Posted March 23, 2017 yes it is Newway air and which pinion angles ? the diff ones? Quote Link to comment https://www.bigmacktrucks.com/topic/49241-shake-that-thing/#findComment-365236 Share on other sites More sharing options...

Like was said by J Hanncock ,the bags too high or too low with cause the u joints to bind along with other issues and you'll have a vibration. I didn't really think of that because it's there loaded or unloaded.

ws721 Posted March 24, 2017 Share Posted March 24, 2017 Try dumping the air suspension while driving and see if that changes it. Do not drive very long with it flat. Also, a bad U joint will cause that. I had that happen. Only way I found it was when I was putting the driveshaft back up I noticed the caps didn't turn freely. Didn't notice anything wrong when it was together and I shook the yoke. Quote Remember if it's got a hood it's no good!

Timmyb Posted March 25, 2017 Share Posted March 25, 2017 Try jacking up a set of duals and rotating them. Could be out of round tyres, or tyres not on the bead properly. Had this happen on a ute but could in therory do the same in a truck.

Glensts Posted March 25, 2017 Share Posted March 25, 2017 We've had issues with vibration at 55 mph and king pins and bushings are wore. Sometimes we can change front tires side to side and it goes away.

Elitedownunder Posted March 25, 2017 Author Share Posted March 25, 2017 Thanks guys can only try these things, I did replace all of the UJ's and have just put on new ride height levers as suggested by J Hancock and adjusted as the others were bent...have a few more jobs on her and will let you know once I test drive her.

Casper1988 Posted April 9, 2017 Share Posted April 9, 2017 What about economy tires that are made out of round. Had a few friends by 400$ steers and realize there was a problem with being truly round. Vibration as various speeds until tires changed out, front ends were tight. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/49241-shake-that-thing/#findComment-366799 Share on other sites More sharing options...

Elitedownunder Posted April 15, 2017 Author Share Posted April 15, 2017 Hi Guys, it was the suspension ride height adjustment for the air bags so once it was adjusted as per the book was all good thanks 1 Quote Link to comment https://www.bigmacktrucks.com/topic/49241-shake-that-thing/#findComment-367470 Share on other sites More sharing options...
hatcity Posted April 20, 2017 Share Posted April 20, 2017 been looking at this post since my truck has a wobble also. have checked everything and signs go to BAD tire. Just got them a short time ago. Had a bad bearing, so replaced. didn't fix, ride height good, no loose tie rods,..... When I replaced the bearings, noticed that several studs would have to be replaced next time. Question-Can I use a small impact hammer to drive studs out while still on truck? or pull hub?
