Hi everyone,
I've got a rather strange noise coming from the drivers side front wheel. It's sounds like a wheel bearing noise, but the wheel bearings have been recently repacked. I've checked to make sure that I haven't accidently left the hubs locked in & it's not the brakes... I thought it may have been a
suspension noise, so I greased up all me nipples, but that had no joy either. Is there anything else that would make that kinda noise?
Thanks
Ben.

Ben,
This is a cut 'n paste from Post ID 28683, that I did last year. Like you I had a 1989 Ford Mav at the time (sometimes I wish I still had it!). NB - it's a cut 'n paste within a cut 'n paste!!
Cut 'n paste starts (again):
I'm not sure if the new Patrols ahve the same front end set up as the old ones, but here's what I found on my old 1989 GQ Maverick (Nissan) ute. It's an edited reprint from a rely I made on the
forum last year. Hope it helps.
Copy 'n past start.............."inside the front locking hub there is a spacer ring. It's easy to get access to it. Just remove the Allen screws (11mm metric) and tap off (gently) the outer hub. Inside there you'll see the locking clutch. Around the outside of that clutch is very thin steel ring that looks like part of the whole assemby. It isn't. It fits between the aluminium outer casing and the inner clutch asembly. These rings can 'catch' on the clutch hub and create high temperatures through friction. When they are really dry and 'catching' they can make a very elusive rattling sound. It took me weeks to track this noise down when it happened to me. Just remove the ring and have a look at it. If it looks burnt or scarred then it's 'catching'. Rub down the high spots on the inside of the ring and on the outside of the clutch assembly with fine emery cloth or wet 'n dry pape, put some grease on it and put it back. Be careful with removing & replacing the circlip. It's tricky........."
Cut 'n Paste ends
I had to do that way out in the bush. It was driving me insane listening to that noise. I sat on the bonnet of the truck whilst my son drove. Hanging onto the bull bar over the front of the truclk............listening, listening..........I musta been mad but I found it.

Ben,
I hpe that fixes the problem. The noise in
mine was more of "chattering" sound than the "buzzing" sound of a worn wheel bearing.
Wheel bearing don't rattle - they whine or "buzz".
The wheel bearings in the GQs are, like almost everything else on 'em - bulletproof.
The only other issue that I had was the drivers side front disc caliper used to stick and wear out a set of pads within 100km!! Used to chew the bejeezzus out of the disc rotor - metal to metal in no time. But you don't know that's happening until it's too late and you can hear the metal pad backing scraping on the rotor.
I drink "Carlton Black" ;)
Good luck
Bilbo

That's really wierd coz when i bought my maverick it had a deep scores on both sides of the disk rotors and both sides of the car... like the caliper had stuck a bit. i had to put new discs in as it was deep enough so it couldn't be machined out.
Listening to it, it doesn't sound like a bearing noise... like a whining noise. It might be a combination of noises too, that spacer ring & the calipers joining forces.
Cheers,
Ben

G'day Ben,
I just went through this with the 98 GU, not sure if the GQ is set up the same way but on the GU there is an 'early warning system' on the brake calipers that lets you know your pads are getting low.
When your pads get to a certain thickness there is a thin piece of metal that scrapes lightly in the outside of the rotor to let you know it's time for new pads, if you're like me and don't know about it, trying to figure what this light scraping noise is, is a bloody nightmare.
Might be worth checking.

I was just about to say the same thing.... just give the little flaps of metal a bit of a bend away from the disc and give it a go... What a lot of people hear is when they go around a corner the disc moves over very slightly and makes contact with these warning tabs....
Just don't bend them out of the way completely if you are not going to do a pad change as they are to warn you off chewing out your rotors at metal on metal..
Cheers
