1998 Massey 231

[Dman1981]

If you have ipto you have to pull top cover to replace coupler do not have to split it they usually spin out the splines changed lots of them on four wheel drive units
On the 230 model also saw a lot of ring gears break if it has wet brakes has bigger ring gear and pinion

Start with the easy things first. Is the driveshaft still attached? Does it spin when you put it in gear?
