    I have a 03 T600 KW, it has 700K on it and I have developed a viberation while driving and now you need a kidney belt to drive it its so bad, the truck has had all the tires replaced, radiator replaced, ft spring bushings replaced clutch replaced, the trans overhauled, due to the high to low grinding. the driveshaft rebult with all new u joints and slip joint, and ballanced. the rear shaft check and is ok. dose anyone have any segustions as to what might be causing this tractor to shake constanly whle driving, speed dose not matter, roughly from 30 on up, bobtail is worse, with load still viberates, has anyone had sililar problems and what might be causing this the problem. any help would be greatly appreshated, Thanks KW1

    Check the ride height on the drive axles, from the side the inter-axle driveshaft should look inline with the rear axle's pinion shaft. Too much angle here will cause a vibration and chew up parts. Harmonic damper would also be due for replacement, generally recommended to replace these at 500k.

    any brake drums that have holes drilled in them instead of a slot cut in them are made in china or a even worse place. look for any type of BAL. cuts in them or there not BAL. at all.
