Rattling noise coming from the front wheel hubs.
Good Morning
I need some advice and help.
At the last major service of my GU patrol the dealership had to repack the front wheel hubs.
Since then there has been an infrequent rattling noise in the wheel hubs.
The best way to describe the noise it is like when as a kid on your bike you used to put a footy card in the wheel spokes to make it sound like a bit of engine noise, only louder.
I have had it back to the dealership but they cannot find any problem, yet on occasion the noise persists.
As I say it is infrequent, heavy braking seems to trigger the noise and if I drive in reverse and hit the brakes it stops.
The front hubs are not engaged and are in the fully unlocked position, I have had the wheels off and there is no obvious problem to me.
So my question would be has anyone else encountered this problem, what caused it and how was it fixed?
Thank you all in advance, I hope you can help.

Hey mate, just my theory but reckon could be the backing plate. Check its not bent in and rubbing anywhere, also little stones tend to get caught and cause noises sometimes. .

I am wondering about a sticky piston in the caliper and the pad or shims are vibrating. Seems to stop after reversing or heavy braking, check to see if something isn't caught up but you would think the dealer would find that if obvious.

Can you determine which side is making the noise? Are your hubs Manual or Auto hubs?
If you can determine the side then lock the hubs, take them off, swap sides, and refit and unlock should take about 5 minutes to swap.
The noise you are describing is probably the Auto hub semi engaging. I have heard this before.
When you say the dealer repacked with grease what do you mean? Are you talking about a Swivel Hub rebuild or just the Auto Hub service? How much grease did they use i wonder.

The only good thing about an 80 series is..... the front end?? Wrong!!, the Engine?? Wrong!! the Full Time 4WD system?? Wrong!! Its the NissanPatrol.com.au stubby holder fitted over the transfer lever.

I am he, fear me
Betcha Trumpies re-election chances to a 1/2 a can of flat Southwark they packed the FW hubs with too much grease and the hubs are semi engaging

my guess is they used gearbox oil in the transferr case instead ot atf which causes the axles to turn an try to engage the auto hubs . and / or they have packed to much grease into the auto hubs . pull the filler plugs out of the gearbox and the transferr box stick your finger in and see if the oil seems the same , the transferr box oil should be much thinner atf oil .

Not sure on any of those points.
However when I taken it back they cannot find a problem and they say that what they did would not cause it.

Do you think it could be the ABS sensor engaging?

You haven't said how old your Patrol is, but worn sway bar mount bushes and sway bar link bushes can cause this type of noise. Sometimes when you brake hard or brake in reverse the bar moves slightly and the noise either comes back or goes away. Have a close look at the mounting bushes and see if the bar is sitting in the centre (not touching the bracket). The link bushes may look OK until you remove them and find the inside of the bush is perished and the link rod is rattling against the support bracket.
One way to check is get a rubber mallet and give the bar a belt and listen for a rattle.
