Puma - 'Scrubbing' sound from front right wheel

[Graekynn]

Ok, this one is a little strange, but whether I'm off road or on road, I sometimes get a sound from the front drivers side wheel area and associated vibration through the steering wheel, floor etc. that is akin to a tyre scrubbing on the mudguard.

I have stock size wheels and tyres and stock suspension, and there is no indication of any rubbing anywhere inside the wheel arch, nothing even comes close. However it always happens on a particular right hand corner near my house where some subsidence has caused a minor drop off. As I drive through the corner and the front wheels drop off the sound kicks in as soon as the suspension rebounds and continues for a few seconds then disappears entirely. This is not a sharp corner at all, steering wheel only turned about 90 degrees from centre at most.

Never happens on level road, but can almost always hear/feel it when ascending/rock crawling off road. Its not related to traction control or any other system because no indicator lights come on when it occurs.

Assuming there is no tyre contact with any part of the body, what would be an internal cause for this? Bearings/Diff?

Many thanks!

Dave.

Is the sound there if you had light pressure on the brake (left foot?) as you drive around the corner otherwise normally?

[Graekynn]

Good question....I am normally off the brakes well before I hit the bump so have yet to try it, but will see if it makes any difference and post back.

If it doesn't happen under braking then what would that point to?

Just a shot in the dark to see if it makes any difference. Really shouldn't make a difference. But if it did then you'd have a real good look at front callipers/pads and also check for movement where it shouldn't be related to wheel bearings, suspension etc...

[DiscoMick]

Might be a silly question but could there be a stone stuck somewhere that only rubs when you turn?

[Beery]

Maybe check your front brake hoses. There's a recall out for some 2015/16 models that have an issue with the front brake lines rubbing on the tyres.

Dust shield i thought was a know fault of cracking , This could rub and cause a slight vibration .

Dust shield i thought was a know fault of cracking , This could rub and cause a slight vibration .Yep, a possibility, they've been cracking the bracket since LR added the shield to the front end!

Thanks for the replies everybody, I tried the brake yesterday and it actually stopped it happening, but my clutch foot is a little heavy and I cant be sure I didn't bleed enough ks off to alter the severity of the bump and invalidate the test so will try it again this afternoon with less brake and see.

I have yet to take the wheel off to have a really good look, but its clearly the next step. I will check

calipers
brake lines
foreign material

I did a search regarding the brake line recall and found an article stating affected vehicles fall within the VIN range SALLDWBR8FA461900 to SALLDHRP7FA465615

How do I confirm my vehicle falls within that range? Do I just ignore all the letters and focus on the last 6 numbers?

For sure you only want to have a very light pressure on the brake pedal as you test drive.

Yes the last 6 numbers for VIN range.

My 90 has done this intermittently,(suspected it was the traction control) but always at a time when my eyes were busy elsewhere so could never tell if the TC light was on or not.
It did it again the other night, and fortunately being dark I saw the TC light come on!
The only cause I can think of is I was starting off on almost full lock, & I guess the TC sensed some loss of traction?:angel:

[justinc]

Very likely it is an ABS TC noise. Most likely from either excessive airgap at one of the wheel sensors or excessive wheel bearing play (which shouldn't happen in the td5 onward models as they have a stakeable locknut... if its got movement either the nut isn't tight or the bearing has failed) which can knock the wheel sensor back off the tone ring.

Try tapping the front sensors down until they hit the tone ring, then the airgap will be set as the wheel rotates.
