KW T680 shaking problem

My previous employer used them on everything. As they explained, there’s a lot of gap between the hub and the wheel’s pilot hole. There’s no way the wheel is perfectly centered on the hub and that’s where these centering lugs come into play. They perfectly center on the studs. I never had a shake on the tractors I drove for them. I wish my current employer would use them.

 

I have the same issue. Changed steers, new shocks, shackle bushings, u bolts, changed trailers, checked carrier bearing, ham bone bushings, 3 axel alignment, king pins. Nothing seams to help the vibration.

 

It'd be nice if you listed off all what was replaced. Then at least we can suggest things that you haven't already done.

 

What's interesting about this is we have to identical trucks. They where used up in Wyoming. Traveled mostly on rough ### gravel roads. Brought back to northern colorado. Driven on mostly paved roads. Both trucks have the same identical vibration. Been using mine As a test case. FYI, the picture in my profile is my old truck. Got to old to throw chains. Heat, cold, mud and on call all the time caught up to me.

 

I bet MD Alignment, could get it figured out. If I owned this truck, that’s where I’d go with it.

MD Alignment Services - Makers of MD Alignment QCT Alignment Systems

 

Had Lazar tract in Greeley Colo align the truck. They use the MD system. When I get this figured out, I am going to sell the information to the highest bidder. Lol
