Speed Related Noise

[AD90]

Hi All,

 

I was driving SWMBO Alhambra at the weekend and it's noisy, she has mentioned it before, but you know how it goes (in one ear and out the other)

 

Anyway, It's got a rumble/growl that varies proportional to speed. It gets a little bit louder on a left hand bend and a lot noisier on a right hand bend. Normally, I would have been looking to change the NS wheel bearing, but after lying underneath while the wheel was spun, I could swear it sounds like it's coming from the inboard CV joint.

 

Anyone any thoughts on this? (The boot is not split)

 

Thanks

hello

if you have a wheel bearing on the way out they vibrate as well, long before you hear a wheel bearing noise you get vibrations, the way to detect these vibrations is to spin each wheel while holding on to the coil spring of said wheel,

if the bearing is starting to go you will feel vibrations, do the same with the inner support bearing on the shaft, I suppose the diff support bearings could also cause this but I do not think that this will be the cause.

sounds like a wheel bearing to me is there any play in the bearing? if you cant find it it would let it progress...

Well, I'm pretty sure it is the inboard CV on the Near-side (left)

 

Does anyone know the part number for a 51 plate Alhambra, 1.9tdi, 6 speed, 115bhp?

 

Thanks

I think its the bearing, due to the noise varying according to the loading on turns, i dont think the cv would do that.

 

To prove, dip the clutch while turning to take the load off the CV

Still noisy when I do that, I'll try changing the bearing first.

 

Thanks

If you make a tight turn in a car park, do you get a knock-knock-knock? That would indicate a CV joint issue. Wheel bearings usually exhibit excessive play (jack up wheel and test for looseness). They will usually roar for 10's of thousands of miles before a catastrophic failure.

 

If you do plan to swap the wheel bearings yourself, be prepared for some blood, sweat and tears.....they are ***** tight! I'd consider finding someone with a flypress to press the bearings out of the hubs. I used some steel drifts on an anvil, and a 4lb hammer but it was not easy.

 

Also, the front calliper bolts need a 27mm a/f socket and a 2ft breaker bar. Soak them with WD40 the night before as well.

 

Good luck!

Wheel bearing changed, silence restored (and the car is quieter too :-)) It was a bit of a chew without a press, but to fit the new one, I put the bearing in the freezer and the hub carrier in the oven - job done. I am so glad that I decided to listen to you guys and not change the inner CV.

 

Thanks
