OK , as some of you know about my vibration problem I have been having. I have had a few things done so far , but to bring some up to speed on what is going on , here it is:
About a month ago I noticed a hard vibration starting in my truck , it starts at about 30MPH then gets somewhat worse at 45-50 , and gets better at 70 , but it really is bad when I'm on the highway doing about 65 when I gas it and let off the throttle , it really shakes .
What I have done so far:
Balanced and rotated tires
From some advice replaced all the u-joints and carrier bearing, still there.
Diagnosed as failing Transmission , it is now rebuilt, still there.
Transmission guy talked to his guy and he believes it is a motor problem , maybe the Computer is not allowing a timing advance at higher speeds or even not getting enough fuel to the rail.
OR timing chain is stretched.
The new guy is gonna test drive it in the morning and try to figure it out, it's almost like I am chasing a gremlin here.
Any thoughts on what this could be????
