HI All,
I have had my 85' FJ60 for about 8-9 years now. Body/chassis has 212k miles. Engine has close to 160k miles from donor 84' truck paired with a rebuilt t-case with an advanced adapters 4:1 low gear set and a new h55f transmission.
I have developed an odd jingle noise while under load. When the clutch is pressed the noise goes away. From research i believe it to maybe be a TO bearing or something to do with the clutch plate assembly. However, the noise is extremely inconsistent and is louder at low speeds and sometimes non existent at high and low speeds. The Jingle noise seems to have happened around the time of my engine swap or desmogging of the new engine, my memory is poor, but those two jobs were done close to each other.
The noise does not occur at idle or when i rev the engine in neutral. When the windows are closed and driving, the noise seems to come from the rear of the truck and when the windows open the noise is hard to locate. I get no vibrations while driving. The noise sounds like a set of keys slapping against the frame rails at random times, but consistent enough when under load and not in neutral.
I have checked every nut and bolt under the truck from drivetrain components to the bolts holding down the bumpers. I even tried sticking a bore scope in the frame rails to see if a bolt or bell got thrown in there. One thing i found was a bit of slop in my rear differential in/out and side to side, could it be that?
I have scoured the forums, any help is appreciated.
Thank you!!
