I haven't driven the 80 much in the last month, but know that it has been making all sorts of new noises lately. My wife uses it daily though. My wife dropped it off at work and swapped me cars the other night so I got to drive it home. I have got a major knocking noise in the drivetrain. It seems to be coming from the front somewhere and only hapens when decelerating without the brakes. Really any time your coasting at under 30mph. It does not seem to be effected by engine speed.
It is definitly a rythmic noise that slows as the vehicle slows. The front driveline seems solid. I had six states replace the front and rear driveline ujoints last spring. The rears don't seem to have any rotaional slop, but I can move them 1/16 in each direction across the joint. There does seem to be rotational play in the slip joint on the front driveline.
I tried to pull the front diff drain, but could not find my 24mm socket so I will do that tomarrow night. I totally rebuilt the EVERYTHING in the front axle with the exception of the ring and pinion gears 5 years ago when I bought the rig. It will sicken me if something in that front axle has gone south on me. I got my finger in the fill hole of the diff and the oil looked really grey.
Any thoughts?
I forgot to mention that once tonight when I put it into drive, It was like I was tied to a tree. It moved forward, but was really straining to do so. I put it back in park and then in drive agian and it worked fine. 270k miles on this 93.
