NV3550 Bellhousing

[korisu56]

Mine is running very loud. Any ideas on how to clean it out or quiet it down?

[korisu56]

bump.

NV3550s are inherently (sp?) loud. The best thing you could do is add some sound deadner to your floor. Or turn your stereo up louder...

Rob,

I think his is full of mud.

Yeah, when I press the clutch pedal down, it quiets down.

From my understanding... if you have noise that goes away when you depress the clutch it's the input shaft, and if you only hear noise when the clutch is depressed it's the throw out bearing.

There's been discussion on rof and the consensus is to either run straight mobil 1 5w- 30, or 2 qts mobil 1 10w-30 and .25 qts atf.

Input shaft is very bad right? ****. What does this mean?

Again, I'm no expert, I just remembered reading through a bunch of threads about people having noise issues. It seems like most have had luck with the mix I listed above. And it seems like most were told by the dealership that the noise is normal. My previous jeep had the nv3550 and I remember it being noisy and a pia to shift, especially when it was cold out. If I can find more of the old posts on the nv3550 issues I'll link them up.

Oh for sure. It definitely can be a PITA to shift sometimes, but I'm more worried about the input shaft being messed up. Do you mean it's the shaft by "it's broken" or it's the shaft "just making noise"?

[korisu56]

Ah...input shaft bearing. I'm going to google that to see how hard it is to replace.
