wen drivin my truck on the road i have noticted that it is really noisy wen i get off the gas coming down a hill or into a corner..
it has only started doin it since fittin the duals and am thinkin that the 4spd case is the prob, just wonder ing any1 knows if a 4spd case is normally noisier than a 5spd or mayb its just coz its old and needs rebuilding

I have hear the 4 speed t/cases are noisyer. Mine is noisy (sounds like bearings) when coasting I read a whole lot on pirate and they seem to think it is normal with duals ???

Remember that some of the 4 speed cases are over 20 years old. Helical cut gears require thrust washers to maintain correct mesh, with a bit of age and wear there will be more backlash on decel, as the gears move in the opposite direction of the main thrust washers, causing the gear whine you describe.

I believe you can do this as Marlin sells shift rails to do the conversion.

Never done it but I am sure that the marlin kit is just that - 4sp shift rails!! So it should be able to be done.
