Last few kms coming home last night and I felt a knocking/clunking noise when I turned the steering wheel either way, coming from the from left wheel area.

Not necessarily on full lock, wheels can be straight and appears to be some looseness somewhere.

Will take the wheel off and inspect hub bolts and everything around there.

Hope it's not the outer driveshaft. Was the only one I didn't re-grease lately as I couldn't get the end shaft plate off but it wasn't split.

Any clues of what it could be before I jack up the car?

Cheers

Clunking while turning the steering wheel invariably points to strut pan bearings in my experience.
If its clunking on full lock then it will more likely be driveshaft related.

It's not on full lock. Noticed it while parked and wheels straight, if I turn the wheel either direction just a slight clunk. Was afraid it might be one of the new hub bolts that were repaired and replaced recently.

Crap - what and where is the strut pan bearing? Something new to me.:rolleyes:

Is it serious? Should I not drive the car?

Do you have a diagram of what I can look for?

(Have been driving over some seriously bad roads with potholes in the last few weeks) Road construction under way so they direct us onto these awful side roads in complete darkness!.

found this:

Strut Pan Bearings-These bearings at the pan base of the front struts seem to be a weak point on many Alfa 33s. However they are not very expensive, but will require specialist fitting.

I dont think its going to prevent you from driving the car, I had a 1.5 ti doing it years back and went on for months before getting it sorted.
Get someone to turn the wheels while you get down there and have a listen, see where it actually coming from.
Ive also had an instance on another car where the spring has moved in the pan slightly and this can also clunk when turning the steering wheel.

Have a look here, there are some diagrams of suspension components.
Diagrams of most components actually, a very useful sight

Thanks Ian will do.

Got a drive to the weekend family house coming up. Before doing that 120 kms I will whip the wheel off and check all the critical bolts (hub etc).

If all is tight then I'll drive and get a friend to check out the noise with me at the weekend.

Been thinking about changing the struts to progressive ones anyway. Might be a good opportunity to do this all in one.

The roads here are hell. Potholes everywhere and the QV model is one bumpy ride on the standard springs.
A bone shaker! Progressive will take up some of those cobble style roads I believe.

yes mate.. pretty sure there are only two types of pan bearing.. metal ones for S1 spica struts, yellow plastic ones for the rest (including 164s)

i had the same problem and turned out to be the cv boot at the end of the drive shaft so if its not your bearings next place to check is the cv boot

checked out the car tonight. Didn't have much time.
Full lock - no movement

wheel off, pulled around on the strut spring and heard some groaning/clicking noises. There was looseness there but just a fraction.

Strangely 2 of the hub bolts (inner side) had moved slightly (I marked their position when torqued up) BUT they had moved a fraction clockwise to a tighter position:confused:
I checked their torque again and all very tight.

Put the wheel back on and lowered it.
Then moved the steering wheel side to side. Couldn't hear anything now!!!!

But I need to take it out for a drive to see if it feels weird and I hear clicking again.

Anyway dinner time now.

I need to adjust the ignition timing and put smaller idle jets in so got to sneak out again hopefully tomorrow evening.

mmmm...now I realise the car is pulling to the left slightly when braking.

Track rod end? Does it just need adjustment or replacement?

I will probably take it to a workshop for this to have the dampers checked along with the tracking.

Standard fitment on my Sud! The bearing seizes, and so when the strut turns the spring has to turn with it. The clunk is the spring winding up and then slipping in the pan. You can jack up the lower spring pan and spray some aerosol grease into the bearing, that will make it stop for a while.

thanks evanbottcher.

Not too sure where the bearing is actually located but I'll figure it out. Is it under the plate?

Also when you say jack up the lower spring pan you mean jack the side of the car up on the standard jack point until the spring releases some of it's tension?

Cheers

Look in your wheel arch, at the top of the tyre you'll see the bottom of the spring, which is sitting on a pressed metal pan. Under that pan, between the pan and the lower leg of the strut, is a bearing. On many alfa's (sud/sprint/33/164 + others) the spring doesn't swivel with the strut when the steering is turned (more typical is for the spring to swivel with the strut). The bearing allows this.

Anyway, these bearings like to fill up with dust and rubbish and then they fail. Your S2 33 should have ball bearings within a yellow plastic housing. When they fail you can often see bits of the yellow plastic housing making a bid for freedom from under the spring pan (if you clean all the muck off the area). A quick test is to reach in with both arms and grab each side of the lower pan and try to swivel it. It should turn freely and smoothly but with a fair amount of force as you're winding up the coil spring. You won't be able to turn it far. If it's grindy or sticky or jumpy to turn then your bearing needs replacing.

To do that, remove the strut and apply spring compressors to the coil sping. Remove the top nut, top mount assembly, and coil spring and the lower pan will just lift off too. There is your bearing - replace and reassemble.

Thanks Sprint veloce.

I will take off the wheel and look under the pan.
I've seen some grease in a spray can here.
I'll clean up the area and give it a good squirt.

A couple of months ago I did have an oil leak (cam seal popped out) and sprayed oil all around the wheel, inside mostly.

This oil picked up all the dirt - possibly getting into the bearing.

Cheers
