Ticking noide

[Johnny C]

Hi
My 993 has developed a ticking noise from the outside. When I coast down a straight road at low speed I can hear it, it seems louder when I turn sharp left but that may be the noise reflection. It's the same at idle, clutch depressed as motoring. It seems to tick with each wheel rotation and it's more obvious at low speed. I had the front wheels off last week and they made no noise. Back ones are coming off this week for new tyres. If it's not tyre related, any ideas what it could be?
I had the diff replaced and gearbox rebuild a month ago, only noticed it since then but that could be coincidence

Cheers

Despite the fact that they are not a service item and protected by rubber boots, it could be that one or two drive shafts need repacking with Moly-grease.

I have this done de-facto every two years, irrespective of miles but usually because I tend to use my cars often and hard.

Perhaps an avenue worth exploring?

Cheers,

Bert

Or even, more obviously, a ‘foreign body’ (stone/nail etc) caught in the tyre tread perhaps?
Would point to CV ‘ticking’ otherwise, though.

Have you checked the wheel bearings?

Cheers. I suspected the CV joints, from a rennlist noise diagnostic article. I'll get them checked out when the tyres get changed.
