Been noticing a noise.
So, here are some symptoms:
When I switch into 4 wheel drive and go I don't notice much. But when I switch back into two wheel a grinding sound will start up - very fast sound, like a baseball card in a bike's spokes. Reversing and backing up will make this noise go away.
I read the forums about this and it sounds like the hub. The outside of the car says 'auto-locking hub'. Sounds like this is a common problem. Even my description of the noise is common - I found another thread where I guy described it the same way: "suddenly a noise exactly like a kid holding a stick on the spokes of his bike." (http://www.nissanpatrol.com.au/forums/showthread.php?9905-Front-axle-free-run-Hub-noise-amp-clunk-08-zd30&highlight=auto+locking+hubs)
When the noise first started it would only make a noise after switching back into two wheel drive. But now I have noticed a bit of a noise - though not the same one, when going slow in 4 wheel drive. I don't know if it is there when going fast though for there are too many other noises. I did go and buy a bunch of small screws and washers and, after drilling little holes, I systematically fastened every My patrol is more like a dirty old farm truck so I suspect the grease has long since departed.
I assume it started out not fully disengaging and has now progressed to not fully engaging.
I notice nothing when in 2 wheel drive (after reversing, of course).
I have looked at the manual and read this forum. I am researching what I need to do. Perhaps it just needs a cleaning and a lubrication (for this car is very old and was not maintained at all until I bought it).
Is this an easy job - to at least take it off and give the hub an inspection?
