- 1991 XLT
My truck sat for about a week and a half, the same time it started to get consitently cold outside (state college, pa). drove around after this slump and noticed a vibration shaking the whole cabin when i was in 4th. this vibration got progressively worse and has peaked in intensity now, about 200 miles later. the vibration is not there in 1st, all the way to the redline. shows up in 2nd after 3k rpm. is very bad in 3rd when the engine/trans. is under load. noticeable but not as bad in 4th when engine under load. is very bad in 5th when engine is under load.
changed the oil. took out the driveshaft and had it balanced, its okay. tires are okay. feels and sounds like its coming from up front, such as the transmission. family mechanic says the clutch and flywheel are okay, but it seems to be something with the transmission. perhaps a tranny mount?
1991 XLT manuel transmission. roughly 171,000 miles.
