Okay - this is a tricky one to pin down... or has been thus far, many things can bring about the 'symptoms'.
Have yet to put it up on axle stands and have a poke about, as it maybe something that is not readily visible.
Been experiencing a metal on metal sound, from the front axle area - further narrowed down to OSF wheel well area.. sometimes its a knocking, sometimes sounds a bit like an old timber 'tall ship' creaking under wind, but definitely still metal involved.
- Mainly seem to notice it at slow, urban - pottering about town - speeds, whether the road is bumpy or smooth makes no difference.
- Once on open road and up to speed it doesn't seem to happen. No noise.
- Cornering, roundabouts - even at speed - don't bring it about. In fact the handling doesn't seem altered at all in anyway.
- It sometimes happens when rapidly accelerating, or under heavy braking... but not all the time, or even often.
- When (due to work) I have had to perform a rapid 3 point turn in a side road, makes the noise then (very noticeably) when moving hard on lock, both fwd & reverse, a metallic creaking.
First thought was CV joint....but mechanic friend said I would be unlikely to see the wear if I went under and looked 'inside' the gaiter/boot covering the joint. He said I should pull away on full lock and if it made the noise, then it was CV joint. The noise he described is the one I have had in the 3-point turns (mentioned above)- or very similar - but it didn't make it on the few test runs I did just pulling out/away on full lock. Mech' friend said unlikely to be CV joint then but could be the inner ball joint at other end of the half-shaft.. or wheel bearing..?
I had considered the wheel bearing but I have not had that droning/loud humming that usually accompanies a wearing bearing.
Am going to put it on stands over next day or so and half a bit of a dig around in the area of the wheel/axle..... any further ideas, or points.... obscure (semi-arcane tests even) that should be done to eliminate other causes.
