Nope. Not who's there.

I've got what sounds like an exhaust knock except it's not. Just popped out for lunch and noticed that under brakes (arriving at a roundabout) and turning left (only), there is a slight knocking noise.

Pulled over and had a bit of a look and noticed there was a little bit more play than usual in the front right hub, but I thought I would post this to see if I can save some time on the diagnosis.

Searched the forum and found a few ideas (leaning towards steering rack or the 2 bolts on the hub itself). BUT are there any ideas on why it seems to be coming from the front right and only turning left?

Thanks!

Evan

Its time to check the condition of your wheel bearings, ball joints and drive flange. All of these will create free play in the wheel. The drive flange or wheel bearings may be the weak link here however given the noise under braking. The worn drive flange can creep on the CV splines under braking load and creates a knocking or creeping sound as they do so. It may be your right wheel in this instance, but all things considered they may be evenly worn on both sides. The CV nut may also be loose of course.

Tightening up your CV nut won't cure the problem if it's the drive flange at fault.

Thanks Mick. Sounds like I have a new project.

Loose wheel nuts?

Result. Was a less than finger tight hub nut. Shiiiiiiite! Now retorqued to the prescribed 150lb. No more knock knock.

:shock: :shock: mate of mine had the same problem, had just had his tyres changed and wheels re-aligned, was only 5 mins down the road when he heard the noise... 1 had fallen off. needless to say that K-mart tyre and auto is avoided by all we know... and someone may have been very close to loosing their job there when my mate left there the second time.
good to hear nothing serious eventuated from it though, could have been alot less fortunate.

**EDIT** just re read your post.... "hub".. mixed it up with GT's "wheel" :oops:

If the hub, bearing, CV, Driveflange, Conical Washer and / or nut is stuffed (which is likely), it would only be a waste of a good split pin.

if you car has been to anyone who has touched the wheel for any reason, re-tighten them yourself! i was down to one wheel nut the other week after thinking a tyre place might actually do their job and tighten them properly

The opposite usually happens and the wheel nuts are way too tight.

I know someone who was an apprentice with a brakes garage and they forgot to tighten the wheel nuts. Wheel fell off 100 meters down the road. Both the apprentice and his supervisor lost their jobs on the spot. Oops!

Split pins were in place. Twas just the nut that was moveable, allowing the whole shaft to wobble about. Sorted now.

If it happens again, pull the drive flange off and look on the back for wear where the bearing sits against it. When they get like that their splines are usually worn too. I had to replace one recently for the same reason.

Yep, had to replace both mine. Only got about 40 years use out of 'em. What a bugger!

But after paying $1500 for a new clutch for the Suh-barr-roo, never will I complain about the price of mini parts :P

How can the nut be loose but the split pin in place? Not torqued properly in the first place? In that case it's been loose (and fretting) since it was put on. Perhaps not enough to feel/hear, but loose. The reason you suddenly felt it is because something is now missing some metal....
