Lucky dogg Posted November 14, 2017 Share Posted November 14, 2017 Hello all, I have a 1983 Mack superliner with factory Neway air ride suspension. Ithe is a single Frame and I believe it has 38,000 rears. It does not have a power divider with the switch. I recently put a t2180 transmission is this truck and just got it back on the road and now I am hearing a sound from the front rear. It sounds like a big heavy flat washer dropping from my hand to the ground. It does this sound multiple times in 100 yards. The truck is not skipping a beat and after pulling the side cover off there does not appear to be any teeth missing or damage. Fluid was super clean and no shavings or steel dust at all. All my rearend shops are telling me the rearends blown and they also can't look at it for 7-10 days. That's a lot of revenue to lose with it just sitting. I can also tell you since this noise started a week or so ago, as he ran the truck it has gotten more frequent and louder also. Any help or suggestion would be very helpful! Please let me know.
