Paul64 Posted February 1, 2011 Share Posted February 1, 2011 Hi everyone, I know this is not a Land Rover, but I couldn't think of a better place to get urgent help for Andy and Louise who are travelling down to Africa in a 4x4. They are down in Turkey somewhere and have got a nasty noise coming from their front end and would be grateful for any opinions. http://www.surfingafrica.net/2011/02/01/help/ Thanks in advance, Paul Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 1, 2011 Share Posted February 1, 2011 Sounds like something stuck and rubbing against the wheel, or maybe against the venting in the brake disc? Really can't think of a mechanical failure that would produce that sort of noise.... possibly a CV I suppose, but still a strange one.

I suggested break disc, but thinking about it you usually get a higher pitched noise than that in the video. What about a collapsed bearing?

FridgeFreezer Posted February 1, 2011 Share Posted February 1, 2011 If it was engine speed related it sounds like a very poorly PAS pump or something of that sort, wheel-speed wise there's only so much there (wheel, disc, hub, bearings, cv) and I would think visual inspection / a bit of investigation (eg check the wheel bearings, spin the wheel) would turn it up pretty quickly.

Thanks John. I have put a link to this thread directly on their blog request for help, so any suggestions should be picked up by Andy and Louise pretty quickly.

elbekko Posted February 1, 2011 Share Posted February 1, 2011 Sounds like a PAS pump indeed. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 1, 2011 Share Posted February 1, 2011 It does beg the question, if it turns out to be any of the reasonably obvious faults listed so far, how is it that they can manage to post a video on youtube asking for help from the middle of nowhere, but not locate & fix it of their own accord Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 1, 2011 Share Posted February 1, 2011 I can't look at the vid from work but if they are on gravel roads in Africa a stone stuck in the caliper or disc guard would be most likely. We get it all the time here - sounds like a wheel bearing totally collapsed - often disappears quite quickly. Reversing up fast and slamming the brakes on hard sometimes shifts it, if not take a wheel off or wait for the stone to wear out Quote Link to comment Share on other sites More sharing options...
simonr Posted February 2, 2011 Share Posted February 2, 2011 Difficult to diagnose without more info. Get them to video the car from stationary, accelerate to a speed and decelerate back to zero with a gear change in the middle. Try revving the engine with the vehicle stationary also. This will show whether the noise is engine or wheel speed related - or unrelated to either. It sounds like it could be air in the PAS system. If it were a wheel bearing, I would expect the frequency to wobble as it drives. Something trapped in the brake pad as Steve suggested could do it, but I would expect a more metallic sound as the brake disk will tend to 'ring'. If it's not the PAS, I would be inclined to take that wheel off, take the caliper off and inspect it carefully. Si Quote Link to comment Share on other sites More sharing options...
tacr2man Posted February 2, 2011 Share Posted February 2, 2011 Sounds like a freewheeling hub trying to engage ? (on my laptop) ! Jack it up see if wheel wobbles about that will identify wheel bearing . also will identify if splines worn etc Quote Link to comment Share on other sites More sharing options...
Happyoldgit Posted February 2, 2011 Share Posted February 2, 2011 All he above plus try it in reverse too. Quote Link to comment Share on other sites More sharing options...
Paul64 Posted February 4, 2011 Author Share Posted February 4, 2011 Thanks guys for all your input and help. I have just had a look on the Surfing Africa site to see that the noise has gone without any intervention, so not sure what the problem was. I am more than a little disappointed that they couldn't be bothered to thank you all for your quick responses and valuable input, but maybe I'm expecting too much http://www.surfingafrica.net/2011/02/01/help/ Quote Link to comment Share on other sites More sharing options...
