wheel noise..

[mickey]

hi gang..i hate describing noise, but noise is what i've got, so here goes..

ok, situation report.kinda pre noise breifing if you like..

new bf goodrich mud terrains fitted, 31x10:50x15..great tyres, but a bit of a pig for picking up stones in the treads..after parking on a gravel drive, sounds like you're pebbledashing the chassis on take-off..

now, i've got kinda used to that, and getting quite adept at jumping out and pinging the odd stubborn rogue out from the rubber..

oookay..now i've got a "stone" in the offside rear..but i haven't..trust me, i've been around the boots a plenty over a period of four days..no nails nor stone, but the horse's hoof clip clop is deffo there..with the window down its quite loud..does it in drive, does it in neutral, does it a ten mph and a whole lot quicker at 60..

on the way to work this morning i had a brainwave.close the window, and open the passenger one.guess what? its there too, just as loud..it now sounds as if i've got stones in the treads of both rears..there is nothing in the treads..

maybe unrelated, but now there is another sound..i noticed it on the return leg..crawling out of the gates i could hear a distinct "stiff brush on the inside of a metal dustbin lid" sound..and no, i haven't tried that..its similar to what i'd "imagine" binding brakes to sound like..not a squeak, more a light s****ing..it sounds like the rear again, but i've been made a fool of before, i'm open to suggestions.

it makes the noise intermittently..unlike the ticking, which is permanent, and speed related..its happened twice on pulling away whilst parked..i never use the handbrake..it goes, then returns, five seconds and its gone..at one point i thought it might have been throttle position related, as i could "hold" the noise on the foot pedal..butthere isn't really much, if any pattern.

the only thing i noticed, whilst driving with both windows open, and through a built up "echo zone" the noise seemed apparent left and right, but again, could be audial illusion..

my options for the grating would be rear shoes? recent slush might have had an effect of sorts..the "ticking"..well, unless the surfing brains can come up with anything else, i'd say it was a peculiarity of the tread pattern, but why the noise doesn't seem evident from the front is a bit of a puzzler..

obviously, although she drives fine, my concearn is that the noises are related and need some urgent remedial attention..just don't tell me its a bomb.

Rear wheel bearing failed?

Suggest you jack up the entire back axle so both wheels are off the ground. Put the axle on stands and secure the car from rolling forward. Run the engine slowly with the car in drive so the rear axle turns. You might hear exactly where the noise is coming from.

You need to get some smaller (or bigger) gravel on your drive too!

If it was coming from the front, i would say the brush on dustbin sound was brake pad wear indicators, which are little metal tabs designed to touch the discs when the pads get low. They make a sound that sets your teeth on edge if you ignore it for too long.

As for the clicking from the back, try what Laser_Jock suggested. You never know, you might have a Lockrite automatic diff locker fitted! They click when they disengage themselves, especially on long sweeping bends. It would be a happy bonus if that is what it is.

C V joints click, especially when turning!

I wouldn't bother trying to locate a noise from inside the vehicle. I had one from the front. Driver window open yes its this side, shut window open passenger window, no its this side. Open both windows no its both sides, tuned out it was passenger side but I was convinced it was drivers side.

I had BFG MT's 31x10.5x15 fitted on mine, had no noise from them at all unless hard cornering and then you could hear the rubber biting on the edges of the tread.
Try putting front tyres on back etc, see if clicking noise moves from front to back. Front noise could well be brake related, although there are wear indicators and they squeal like a pig someone had broken them off mine. Obviously didn't know what they were for and had a sort of faint brushing sound before the crunching started.
Possibly front noise could be the bronze bushes starting to wear??

right, thanks for the input so far..the 12 mile journey to work this morning wasn't too experimental as peak flow traffic dictated the pace somewhat..however, i was given the oppertunity to make an early departure, so was able to take the scenic route home and still get back in time for tea.

barely left the premises, straight road and slight downhill allowing me to make some progress at idle..the scratching noise is there, intermittently, so its not pedal position related nor any issue with cornering..i like the pad indicator theory more, it "sounds" right..so, where is the noise coming from? ok, i "imagine" its coming from the front, and so it does, untill i think it might be the rear..koi's right of course, i argued with a mechanic untill i was blue in the face that the wheelbearing noise on my nissan was nearside front..he was right, i was wrong..who was i to say, i was only the driver, he had the spanners.

so, what had the fellas posted on the topic before i left for work? urm, a joke about gravel sizes, automatically dissengaging diffs, wheel bearing.hmmmm, lets see..i open the door and lean out, then a bit more and juust a, no, wait, this isn't clever methinks..windows down, tick tick clip clop...then stops, two maybe three seconds and its back..rythmic and certainly wheel rotational speed related..still sounds like a hard shiny round pebble, but of course, its not..

theory..my certainty that the noises were eminating from the rear wheels has clouded somewhat..the pads thing sounds reasonable..thinking about it, the brakes were "clunky" a while back, which i put down to wading the old gal in two foot of crystal clear water..they seem fine now, but squeak every now and again, just a tad...

diagnosis..well, weather permitting, i'll check it all out over the weekend..the stone noise has well and truely baffled me..koi said his bf's never made that noise, mine didn't either before the mystery began, so, ok, its nowt to do with the tread pattern..the important thing for me however was that the noise wasn't indicative of an impending gearbox departure scenario or something..i can live with the ticking for a few days yet..

my solution? to make a new year resolution to visit tony sometime soon for a full monty service..in two years of surf ownership i've neglected certain greasing and lubrication aspects, not to mention diff oil and auto box fluid changes..i guess its gonna catch up sooner or later.

Ok you say you been wading in water, gravel/loose bed?????? if so would take rear drums off and clean out.
After wading at Norfolk I had a small stone/gravel/dirt stuck between the front disc and pad and and made a sort of squealing noise at first then a grinding noise.
As for the clicking at the rear may be a bit of grit in the rear drums from your wading ??????

[Gizmo]

Could be the rear drum protection behind the wheel....after catching this off-road I found that with the Alloy Wheels put back on [was running on 31x10.5/15 with large offset] I heard a noise like something was rattling inside the drum.


It turned out to be the plate had a kink in it and it was catching on a recess in the Jap Alloys.

[mickey]

sounds reasonable koi..i'll get the wheels off as soon as..in fact, it might be a good time to purchase some wheel spacers from the site shop..what size for a widebody 2nd gen with 31'ers?

loose river bed? yeah, i guess, but nothing like the mire you're wading through in the avetar..the river i crossed is the cleanest chalk bed waterway in the uk..a few weeks ago the local land rover club were going through it..i stopped, and suggested if any of them needed towing out, i'd be available..that went down well.

tell you what, i'm glad the guys at the tyre fitters put copper slip on the wheels before they replaced them..i thought they'd been welded on at one point..

[JimL]

Silly suggestions: you dont use the handbrake at all, how about the cable is loose inside the drum.....also you have an underslung spare wheel chain rattling around coz theres no spare attached

[Koi]

Well is it solved yet, we need to know

[mickey]

nope, sorry guys..ok, the noises are still there, but my workload has neccessitated driving to work in the dark, driving home in the dark and parking in an unlit driveway..

the scratching sound, well, i'm sold on it being front off-side pad related..the noise will vanish on a quick tap of the brakes..my proposed investigation last weekend was scuppered by the weather, but it will be done, and i promise a full report will be forthcoming.

the clicking sound, well, i imagine its associated..during the week, i had the oppertunity to sling a spannerman into the rear with windows down..he concurred that the noise was a pretty good impersonation of a stone caught in the tread, except that every now and again, it would do a little triple click shuffle.he couldn't guess at the cause, which didn't really help, but he "felt" it was front wheel related and tied in with rotational speed..

other than that, there are no hot spots on the wheel or tyre, and the brakes are working fine..i'll keep you informed, whatever the outcome, have no worries.

[da SLUG man]

have you checked the wheelnuts are tight??
that would make a clicking sound that usually gets louder when braking... but if it's been like it a while, the wheels would have fallen off.

[Woodzie]

It might be a uj about to go
mine made a clicking noise then a squeeky noise

then it started to vibrate like ****

no coments from the slug about that please it might lower the tone
