My 53 3100 Rear-End whines like a baby with out a noon nap and an empty bottle. If I throttle it to keep some torque on it then I can keep it to a minimum moan. When I let off the gas and coast then it is so loud people look from the curbs. I took the rear cover off and cleaned out all the 50 year old heavy weight oil/grease and some light metal pieces. I called a shop and will have a 3:55/1 installed soon. It is a 4:11/1 with a granny 4 speed.

My question is if I loosen the right side bearing and tighten the left side to move the ring closer to the pinion will I decrease the noise? When I move the rear end inside with the cover off by hand it will move about 2 to 3 inches in the ring and pinion gear before any wheel movement. I think that is called the lash? I am looking for a temporary fix as I am going to drain the rear end oil one more time to try to capture anymore metal pieces so I didn’t do any damage to the tubes or the bearing races so I can drive it a few more times before I have the rear end converted.

BTW I went to a truck shop that handles Tractor Truck parts and replaced my stock with a drain plug that is magnetized so the metal should all be there if I missed any.

Thanks John
