4spd case really noisy in deceleration

[hypo]

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

[Punchy]

thats just way to vague

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 ???

yeah i have heard that the top shift cases r noisier a mate of mine has one that he said i can use 2 rebuild it and swap it over with mine so ill look into it

[Area54]

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.

yeah that makes sence Troy thanx mate ill look into it.

can any1 here get good prices on rebuild kits ???

or is it possible 2 get another 5spd case and use my 4spd shift rails in it so it thewn becomes a top shift case and then run that behind my duals ??

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.
