ChevyTech77, So I happened to have some sand bags sitting around the shop. I put about 15bags 500-600lbs in the truck and drove home and guess what no shaking at 50-55. There is a slight vibration at 45 but nothing like it was before. So is there a solution to Frame Beaming from GM?
I was talking to a friend and he said I may need to have the tires Speed/Forced balanced, also I will check my driveshaft for a possible missing weight.
Truck shakes at speeds between 48-52mph and above 60mph. Did it before and after new tires where installed. Replaced both drivetrain ujoints and rear brake pads. I dont really feel it when braking except when coming down through the speed range of 48-50mph. When I replaced the rear pads the calipers where sticking so I greased the retaining pins/bolts. Any sugestions of what could be the issue?
Thanks for any info...
