Hi there,
I am sincerely hoping that you can help me...
I have a 1993 Nissan Patrol Y60/GQ with TD42 engine (naturally aspirated) and manual transmission with 430,000 km on the odometer and I live in Cyprus. My truck is a Right Hand Drive vehicle. I believe you drive on the same side of the road as us, in Australia.
Recently I am hearing a new noise from the front of the vehicle.
It sounds like a whirring/ticking noise that a spinning object would make (like a bearing).
The sound is apparent during acceleration and deceleration. The faster the vehicle is going the faster the whirring noise (i.e. it appears that the spinning body making the noise rotates more quickly as the car speeds up and vice versa).
The sound occurs in all gears.
When the clutch is pushed in, the sound vanishes immediately.
Based on the above are you able to identify what the problem could be potentially?
It was suggested to me that this sounds like a transmission issue (either with a transmission bearing or a transmission gear). Can you verify this diagnosis?
Before I go ahead and drop and strip the gearbox is there anything else I should eliminate first?
And if I do go ahead and drop the gearbox are there any other jobs it would make sense to do while the gearbox is off? (i.e. changing the clutch, replacing oil seals and/or gaskets in the transmission, replacing all the bearings in transmission even if some of them look ok... etc etc)
Thank you so much for any advice you are able to offer!
Regards,
Alex
