Title: Transfer Box Whine
Post by: Miniman on January 20, 2009, 18:42:17

Hi guys I fit a discovery 300tdi transfer box last summer to my 110 300tdi and it whines......

It talks in all gears Hi & LO 4x4 and non. Is there a easy answer to it. What bearings usualy make all this noise ?

Is it not the cut of the teeth on some aftermarket transfer box input gear that can cause the whine?
Ashcrofts say ....

I have just fitted a new cross drilled input gear to my LT230 and it whines, is this normal?
Some "pattern" gears are not "crowned" during manufacture and will whine because of the edge contact this creates

Some of the later transfer boxes have a 'Q' part number who's descriptions say mean Quiet, maybe you have one of these previously?
