Thread: Puma gearbox to Transfer case shaft

What are the signs that the gearbox to transfer box adapter shaft splines (I think that's what it is called) needs greasing. My Puma has developed a resonance cycle like a low rumble, that you can feel and hear under load. I have read that the lack of lubrication at this point is a concern. I do not know if this could be cause of my problem but I have not been able to track it down. The resonance varies in pitch but the each cycle its the same (Its a bit hard to explain) . Its sounds like it could develop into something serious.

I also have had this in both of my PUMA's, the TD5 does not do this, but I think that's because it has a Dual mass flywheel, whereas the PUMA is a solid flywheel, so there is not rotational damping in a PUMA. I've heard you will also get this in a TD5 if you go with a solid flywheel upgrade. That shaft you mention - you might be able to get small amount of backlash perhaps noticed through gear change clunks, but other than that it appears to be symptom free until the splines strip.
