Gear box make a nosie - 2005 GMC Canyon

Ring gear may have damage. flywheel may be cracked .remove starter and inspect flywheel

check and see if they are plugged in check for bad fuse

Have your motor supports checked. Also the drive shaft could be causing the problem if that knocking is not coming from inside the motor.

Possible power steering pump failure

I doubt it.
Usually when the pump fails it smokes the belt.
If the steering wheel will not turn and the fluid is contaminated, I would say the problem is the gear box or rack and pinion depending on the make model and year.

Hi Michael, If the noise changes when the clutch pedal is held depressed the problem will more likely be related to the clutch assembly and in particular with the clutch thrust release bearing. To attend to that will mean removing the gear box which means replacing the plate, cover and bearing will prove more economic. Regards John

Rotors are touching making the noise.. Could be bad bearings or clearances that are to tight. Rebuild or reset rotor clearances.. Uses shims to work the rotors in or out on the helical gears. Shims behind the gears.

sounds like the gear box the teeth are chewed up from lack of lubrication have to take it off and check the teeth and fill it back up with oil make sure none the gears are missing teeth sounds like lost some teeth

if the nosie is comming from the case then the chain is slack from wear, u will need it rebuilt.

check the gear oil in the differential , check if the oil is burned or low ,may indicate you need gear fluid as its working harder under a load. have a mechanic check the diffferential gear teeth for wear or slippage.
