C70 Steering Noise

[Burnsie]

Hi All

I've an issue with my C70 (2004). When turning at very slow speeds there's a knocking noise? Suspension, wish bones, balls joints even track rod ends have been changed and the knocking is still their!!!!
The noise doesn't happen at speed and the steering seems fine.

Help! anyone have any ideas?????

Hi Burnsie,

Do you mean when you are driving at low speed, and in a turn?
Is it more noticeable when you turn left, or turn right, or the same?
Does the noise correspond to speed of wheel rotation?
Does it sound like a "clacking" rather than a click or a thump?

It might be a CV joint, usually the outer.

Thanks for your reply, yes normally at slow speeds, more when turning right but does happen when turning left sometimes, (hard turn) makes a loud(ish) clunk noise!

did think of the CV Joints ! that makes more sense than it being the rack!!

Yes, typical worn CV joint symptoms.

Just spoke to the garage (Steve @ Local Motor Services) who is of the same agreement. He is ordering a couple of CV Joints to replace such.

So far the linkages, track rod ends, ball joints, front and rear shocks and wish bones have been changed.

This started as a fun car for the summer, by the time its finished it'll be like a new car

All for the love of Volvo !

...don't forget the wheel bearings, although this is usually more of a rumble.

Oh god that'll please the garage lol

You may actually have a point. I think i will have the CV's replaced and then see

On the plus side most of the labour involved to do the front wheel bearings is the same as the outer cv joints so there shouldn't be much more labour cost but the wheel bearings themselves are a good chunk of money for a reputable make such as SKF.

I've found a garage that is like a golden nugget for Volvo's. He's been able to find parts at a blink cheaper than going to scrap dealers and he's labour rate is well realistic bordering cheap !
Two CV's supply and fitted (based on the most teeth) £110
Cant argue with that!!

Does the knock only occur once on each turn? A fairly common problem with this type of suspension is sticking in the strut upper bearing, which has the symptom of a single "boing" sort of thump on low speed full-lock turns.

Fortunately, Volvo blessed this strut setup with the magic of a bearing that can be changed without dismantling the strut - but it still has to be unbolted from the wheelarch tower. One of the easiest strut upper bearings out there, very quick!
