Front Input Shaft/bearing

[06silverado4.3ss]

i have a 06 silverado with the 4.3v6 5sp. i have aslight howling noisy when i go to pull out and some times while i am rolling without my foot on the gas. as soon i as give more gas the noisy goes away. this only happens sometimes. any ideas? 55k

 

 

also if i rev the engine with the clutch in no noisy, but i i pull the clutch out about half way and rev the engine i get a ticking noisy. also this does this going down the road. but if i press the clutch in and rev no noisy.. this also happens sometime not always.

 

 

any ideas fixes would be appericated. thanks

Just replying so you know your computer is working!

 

Not up on the newer 5sp manual tranny's but I have the old NV3500 in my 88 Chevy. They are known for having bad input shaft bearings and the resulting noise. I thought GM had that under control in the mid 90's? Maybe not.

 

Could be the throw out bearing..but from my experience..it's probably the input shaft bearing. I installed (3) different NV3500 tranny's in this truck...and all of them make the same noise you describe. I just got used to the noise after about 40,000 miles.

 

There is a specific lube for the NV3500..but I mixed in some heavier stuff anyway...it's still holding up "and noisy".

 

My next truck will have a NV4500.

 

Take care

BTW: The entire tranny must be disassembled to replace the front bearing.
